[0045] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0046] In modern Web application development, rich text editors have become an indispensable part. They have greatly improved the convenience and efficiency of users editing complex text content online, and realized the "what you see is what you get" editing experience. Common rich text editors such as CKEditor 5, UEditor, TinyMCE, Froala Editor, etc., not only support basic text formatting functions, but also can better handle complex content copied and pasted from document processing software such as Microsoft Word, including text styles, lists, tables, images and complex layouts, providing users with an editing experience close to the native Word application.

[0047] However, although these rich text editors perform well in content input and formatting, they face many limitations when it comes to content output, especially when it comes to conversion to Word document format. First, these editors do not support directly exporting edited content as Word documents, which limits their application in scenarios where Word format deliverables need to be generated.

[0048] To solve this problem, a variety of online HTML to Word conversion tools have emerged on the market (such as HTML to WordOnline, Zamzar, Convert Files, etc.), which generate Word documents for users to download after users upload HTML files and convert them on the server side. However, this method has significant data security risks, especially for documents containing sensitive business data, uploading them to third-party services for conversion may lead to data leakage, which does not meet the strict requirements of enterprises for data security.

[0049] In addition, existing HTML to Word tools have functional limitations. They can only convert the entire HTML file into an independent Word document, but cannot support inserting HTML content or fragments into a specific location in a predefined Word template, which limits the flexibility of document formatting. At the same time, these tools cannot automatically apply the predefined styles in the Word template (such as cover, header, footer, multi-level title, etc.), making it difficult for the generated Word document to meet the format requirements in specific business scenarios.

[0050] In summary, the current rich text editors in Web systems have significant technical bottlenecks in outputting content to Word documents, and the existing online HTML to Word tools have problems with data security and functional limitations. Therefore, it is particularly urgent and important to develop a solution that can not only ensure data security, but also flexibly support the conversion and insertion of rich text editor content or web page content into Word templates, while retaining or applying template predefined styles.

[0051] Based on this, the embodiment of the present application provides a document processing method based on rich text data, based on the HTML structure of the rich text editor to store content, combined with the Office Open XML (OOXML) technology at the bottom of the Word document, to achieve precise alignment of HTML tags with OOXML document content storage tags, as well as effective mapping of HTML styles with OOXML document styles. Furthermore, the present application also implements a dynamic content insertion mechanism based on the Word document template, allowing users to directly insert content or HTML file fragments in the rich text editor into the specified location of the Word template, while retaining the predefined styles in the template, such as cover, header and footer, multi-level title, etc., thereby perfectly meeting the business scenario requirements that have strict requirements on the Word document format or need to follow a specific template.

[0052] Before describing the embodiments of the present application, the concepts that may be involved in the embodiments of the present application are described below:

[0053] Rich Text Editor: Rich Text Editor (RTE) is a WYSIWYG text editor that can be embedded in a browser. It provides editing functions similar to Microsoft Word, such as font setting, color adjustment, image insertion, hyperlink addition, etc., making it convenient for users to edit and format articles or information.

[0054] HTML (Hyper Text Markup Language): A standard markup language used to create web pages. Through HTML, developers can tell browsers how to display web page content, including text, images, links, tables, lists, etc. HTML documents are composed of a series of HTML elements, which are defined by tags.

[0055] Document Object Model (DOM): Connects web pages with scripts or programming languages ​​by storing the structure of a document (such as the HTML that represents a web page) as objects in memory.

[0056] HTML DOM tree: A programming interface for HTML documents that represents the structure of a document and allows access and manipulation of these structures through programming languages ​​such as JavaScript. The DOM tree is a hierarchical data structure that represents the entire HTML document as a tree structure consisting of multiple nodes. In the HTML DOM tree, each element is considered a node.

[0057] Word document: An electronic document format created and edited using Microsoft Word software that supports rich text formatting, pictures, tables, hyperlinks and other elements.

[0058] Extensible Markup Language (XML): A language strictly serialized by the Document Object Model (DOM).

[0059] Office Open XML: XML-based office document format that supports documents such as files, tables, memos, and slides.

[0060] In an exemplary embodiment, as shown in FIG1 , a document processing method based on rich text data is provided, including the following steps 102 to 108. Among them:

[0061] S102: Parse the HTML content in the rich text editor to obtain an HTML node tree.

[0062] Alternatively, commonly used Web rich text editors mainly include CKEditor 5 / , UEditor, TinyMCE, Froala Editor, etc., which generally store content data in the form of HTML, providing users with an online "what you see is what you get" editing experience. Therefore, when processing the content of a Web rich text editor, it is necessary to parse the HTML fragment of the content data and construct an HTML node tree (i.e., HTML DOM tree). Among them, the HTML DOM tree is the programming interface of the HTML document, which represents the structure of the document and allows these structures to be accessed and operated through programming languages ​​such as JavaScript. The DOM tree is a hierarchical data structure that represents the entire HTML document as a tree structure composed of multiple nodes.

[0063] For example, you can use the open source Jsoup component to parse HTML. Jsoup is a Java HTML parser that can directly parse a Uniform Resource Locator (URL) address and HTML text content. It provides a very labor-saving API that can retrieve and manipulate data through DOM, CSS, and JQuery-like operation methods. Jsoup implements an HTML DOM tree that is consistent with the browser rendering effect, effectively ensuring the consistency of the parsed structure with the structure that the user sees through the browser.

[0064] S104: Determine a document storage component and a style definition component of the template document according to the document format standard definition; the document storage component is used to store document content, and the style definition component is used to store document style.

[0065] Optionally, the document format standard definition refers to the Office Open XML (OOXML for short) specification, which is an XML-based document file format used for documents of Microsoft Office applications (such as Word, Excel, and PowerPoint), and defines a set of detailed XML schemas for representing the content and structure of documents, including the structure, style, settings, representation of elements such as charts and images of the document itself. When converting HTML content to a Word document, in order to ensure that the converted document content has a consistent style with the Word document, by parsing the document structure under the OOXML specification, it is possible to determine how the content and style in the Word document are organized and managed through the OOXML specification, and edit, modify, and extend the document accordingly.

[0066] Exemplarily, the main structure of a Word document is shown in Table 1. As can be seen from Table 1, the content of the document is mainly stored in the / word / document.xml component (ie, the document storage component), and the style information of the document is mainly stored in the / word / styles.xml component (ie, the style definition component).

[0067] Table 1

[0068]

[0069] S106: traverse the nodes of the HTML node tree, map the nodes to the document storage component, obtain the document storage structure under the document format standard definition, and map the nodes to the style definition component, obtain the document style structure under the document format standard definition.

[0070] Optionally, in a rich text editor, the HTML content entered by the user usually contains various tags (such as , , , etc.), which are used to define the format and structure of the text. However, when these HTML contents are saved as Word documents in OOXML format, these HTML tags are not directly mapped to the corresponding XML tags in document.xml. Instead, OOXML uses its own tag system to represent the format and structure of the document. These tags may be similar to HTML tags in semantics, but there are differences in naming and structure. Similarly, there are tags with specific styles in HTML. When these tags are converted to OOXML format, in addition to being mapped to text content fragments in document.xml, they also need to be mapped to style definitions in styles.xml.

[0071] Exemplarily, by traversing the nodes of the HTML node tree, the HTML content in the rich text editor is converted into XML format to obtain document.xml (i.e., document storage structure) in OOXML format, and the style of the HTML content is mapped to the style in OOXML to obtain styles.xml (i.e., document style structure) in OOXML format, ensuring that the converted XML format is consistent with the effect of the HTML content.

[0072] S108: Generate an XML document defined under the document format standard based on the document storage structure and the document style structure, and process the template document according to the XML document to obtain a target document.

[0073] Optionally, the Word document stores the converted HTML content, including text, images, tables and other elements, through a document storage structure, so as to maintain the integrity of the content. At the same time, the Word document stores the converted HTML style through a document style structure, so as to ensure that the converted Word document is visually consistent with the original HTML page. The HTML content is converted into OOXML content by generating a corresponding OOXML node for each HTML node, and these sections are organized into document fragments.

[0074] Exemplarily, a template document usually contains a basic document structure and some placeholders. By traversing the content of the template document, the generated document fragments are inserted into the placeholder positions specified in the template document, replacing the original placeholder content, and finally outputting a complete OOXML document (ie, the target document).

[0075] In the above-mentioned document processing method based on rich text data, by converting the HTML content filled in the rich text editor into an HTML node tree, according to the mapping relationship between HTML node tags and XML nodes defined under the document format standard, the HTML nodes are converted into nodes of XML document content, the style content in the node tag data is parsed, and the XML document style that complies with the document format standard definition is constructed, the XML document is output according to the node content, and the XML document fragment is inserted into the tag placeholder position specified by the template document to achieve the output of the final target document. This can not only ensure data security, but also flexibly support the conversion and insertion of rich text editor content or web page content into Word templates, while retaining or applying the template predefined style, thereby meeting the document needs in multiple business scenarios.

[0076] In an exemplary embodiment, the step of parsing the HTML content in the rich text editor to obtain the HTML node tree includes: identifying the HTML content in the rich text editor to obtain HTML tags; HTML tags are used to represent HTML elements in the HTML content; an HTML node tree is constructed according to the HTML tags; each node in the HTML node tree represents an HTML tag.

[0077] Optionally, first identify the HTML content in the rich text editor, obtain the HTML content from the rich text editor, which usually includes multiple elements such as text, pictures and tables, and then parse these elements to identify the HTML tags of these elements, wherein the HTML tags are used to define the structure of the HTML document, for example Indicates a paragraph, Indicates pictures, etc.

[0078] Further, a Document Object Model (DOM) tree is constructed based on the parsed HTML tags, where the DOM tree is a tree structure in which each node represents an HTML element in the document, that is, an HTML tag. For example, in an HTML document, the root node is usually an element, which contains and two child nodes, the latter of which further contains all visible content on the page.

[0079] In this embodiment, by parsing the HTML content in the rich text editor into a HYML node tree, the HTML content can be structured and represented, clearly reflecting the element hierarchy and relationships of the HTML document, ensuring the integrity of the content when converted to OOXML, and further ensuring that the converted OOXML document is consistent in format with the original HTML content.

[0080] In an exemplary embodiment, the step of mapping nodes to document storage components to obtain a document storage structure defined under a document format standard includes: according to a preset first mapping rule, converting the HTML elements represented by the HTML tags corresponding to the nodes into XML elements defined under the document format standard; serializing all the converted XML elements according to the structure of the HTML node tree to obtain a document storage structure defined under the document format standard.

[0081] Alternatively, in the OOXML structure of a Word document, / word / document.xml is the main body of the document, which contains the main text content and most of the structural information of the document. This component is the XML representation of the content that users directly see when editing the document, including elements such as paragraphs, tables, lists, and pictures. In the process of mapping the HTML structure to document.xml, the principle mainly involves the conversion of elements between two different markup languages.

[0082] Optionally, first, for an element in an HTML document such as 、 、 <h1>etc.), formulate a set of mapping rules according to the target XML format (i.e. document.xml of OOXML), which define how to convert HTML elements into equivalent elements in XML. The element may be mapped to the document.xml<w:p> Elements. After that, according to the mapping rules, the HTML DOM structure is converted into the XML structure.

[0083] Exemplarily, as shown in Figure 2, Figure 2 is a schematic diagram of the mapping relationship between the HTML structure and the document.xml structure. It can be seen from Figure 2 that the HTML elements in the HTML node tree are converted into XML elements defined under the document format standard, and mapped one by one to the document.xml structure to obtain the document storage structure defined under the document format standard, wherein the element hierarchy and relationship of the document.xml structure and the HTML structure are always consistent.

[0084] In this embodiment, by mapping HTML nodes to OOXML document storage components, a document storage structure defined under the document format standard is obtained, which can generate XML documents that comply with the OOXML standard and efficiently convert HTML documents into OOXML format, thereby making full use of the advantages of OOXML to improve the quality and efficiency of document processing.

[0085] In an exemplary embodiment, the step of mapping a node to a style definition component to obtain a document style structure defined under a document format standard includes: for an HTML element having a style attribute, according to a preset second mapping rule, writing the style attribute of the HTML element represented by the HTML tag corresponding to the node into the style definition component, and creating a corresponding style ID to obtain a document style structure defined under the document format standard.

[0086] Optionally, there are some tags with specific styles in HTML, such as the "paragraph and style tags" and "isolation tags" selected in Figure 2. The style information of these tags is represented by the style attribute in the HTML structure, while in Word documents, the style and data content are well separated. Therefore, for these HTML elements with style attributes, when converting to OOXML, the styles in HTML need to be mapped to the OOXML style system, that is, the style attributes need to be written to styles.xml.

[0087] For example, < / h1> <h2>Take the secondary title represented by the tag as an example, as shown in Figure 3, which is a schematic diagram of the mapping relationship between the HTML structure and the styles.xml structure. As shown in Figure 3, the style information in HTML is parsed and mapped to styles.xml, which defines various styles that can be used in the document. Each style has a unique style ID. The styles in styles.xml define the format of the text (such as font, size, bold, etc.), as well as the layout of the paragraphs (such as spacing, indentation, etc.).

[0088] In this embodiment, by mapping HTML nodes to OOXML style definition components, a document style structure defined under the document format standard is obtained, and style information can be stored separately in the style definition component, thereby achieving separation of style and content, so that style modification can be performed independently of content, thereby improving the flexibility of the document.

[0089] In an exemplary embodiment, the method further includes: establishing a reference relationship between an XML element in a document storage structure and a style ID according to a style ID corresponding to a style attribute, so as to represent a first XML style of the XML element through the style ID; for an HTML element having a style tag, converting the style tag into a second XML style defined under a document format standard; for an HTML element having both a style attribute and a style tag, merging the first XML style and the second XML style corresponding to the HTML element to obtain a defined style corresponding to the HTML element, and writing the defined style to a corresponding position in the document storage structure.

[0090] Optionally, from the Word document structure, we can know that the numbering style of the ordered list is defined in the / word / numbering.xml component, including the format, level, and nested relationship of the numbering. Therefore, for the style definition in styles.xml, the list and list items in HTML can be directly mapped to the corresponding elements in document.xml by referencing the numbering style defined in numbering.xml in document.xml. As shown in the boxed content in Figure 3: w:styleId="3", this style ID is referenced in document.xml: <w:pstyle w:val="3">.

[0091] Furthermore, there are some tags with specific styles in HTML, such as ~ The sixth level heading tag, , , , For various font tags, etc., for such style tags, without considering the style attribute, you can directly define a specific style in the document.xml component.

[0092] Exemplarily, taking text styles as an example, the font, color, font size, bold, underline and other styles of the text in HTML can be defined as styles in Word. The mapping relationship between HTML style tags and document.xml styles is shown in FIG. 4 .

[0093] Furthermore, an HTML element may have both a style attribute and a style tag. For example, To specify the text as bold, the style attribute of the tag is also configured. At this time, it is necessary to merge the result of the style attribute mapping (i.e. the first XML style) and the style converted from the style tag (i.e. the second XML style) to finally form the style required by the Word document.

[0094] For example, taking text as an example, in a piece of text there are both style attributes and , This style tag, then the final mapping result is shown in Figure 5.

[0095] Furthermore, in combination with Figures 2 to 5, it can be seen that according to the above processing logic, the parsing and mapping of HTML tags, style attributes and style tags can be realized. After HTML is parsed into a DOM tree, the DOM tree nodes are traversed in a loop to construct document.xml and styles.xml fragments in OOXML to realize the conversion of HTML fragment content into Word content. After the conversion is completed, the repeated styles in the generated styles.xml need to be merged. Among them, the schematic diagram of the complete process of generating OOXML elements from HTML tags is shown in Figure 6.

[0096] In this embodiment, by merging repeated styles in styles.xml generated by HTML elements that have both style attributes and style tags, display problems caused by style conflicts or overlaps can be avoided, thereby ensuring content integrity when converting to OOXML, and further ensuring that the converted OOXML document is consistent in format with the original HTML content.

[0097] In an exemplary embodiment, the step of processing the template document according to the XML document to obtain the target document includes: determining the area to be processed in the template document; replacing the area to be processed with the document content of the XML document to obtain the target document.

[0098] Alternatively, in actual business scenarios, the content filled in through the rich text editor is often only a part of the actual business needs, and a large amount of content is filled in the Word document template. For example, the "Outline Design Specification" often includes fixed content such as project background, reference specifications, reading instructions, etc., and only the relevant content of the functional design in the "Outline Design Specification" needs to be dynamically filled in by the system, so it is necessary to implement dynamic insertion of Word content in a fixed template.

[0099] Exemplarily, taking the "Outline Design Specification" template as an example, as shown in Figure 7, Figure 7 is a schematic diagram comparing the template document (the document on the left in Figure 7) and the target document (the document on the right in Figure 7). It can be seen from Figure 7 that the area selected in the template document is the area to be processed, which is represented by a placeholder in the template document. By replacing the placeholder of the area to be processed with the document content of the XML document (that is, the selected part of the target document), a target document that meets business needs is finally generated.

[0100] In this embodiment, by replacing the placeholder of the area to be processed with the document content of the XML document, it is possible to not only ensure data security, but also flexibly support the conversion and insertion of rich text editor content or web page content into a Word template, while retaining or applying the template predefined style, thereby meeting the document requirements in multiple business scenarios.

[0101] In an exemplary embodiment, as shown in FIG8 , a document processing method based on rich text data is provided, the method comprising the following steps:

[0102] The HTML content in the rich text editor is identified to obtain HTML tags; the HTML tags are used to represent HTML elements in the HTML content; an HTML node tree is constructed according to the HTML tags; each node in the HTML node tree represents an HTML tag.

[0103] According to the document format standard definition, the document storage component and style definition component of the template document are determined; the document storage component is used to store the document content, and the style definition component is used to store the document style.

[0104] Traverse the nodes of the HTML node tree, and according to a preset first mapping rule, convert the HTML elements represented by the HTML tags corresponding to the nodes into XML elements defined under the document format standard; serialize all the converted XML elements according to the structure of the HTML node tree to obtain a document storage structure defined under the document format standard.

[0105] For HTML elements with style attributes, according to the preset second mapping rule, the style attribute of the HTML element represented by the HTML tag corresponding to the node is written into the style definition component, and a corresponding style ID is created to obtain the document style structure defined under the document format standard.

[0106] According to the style ID corresponding to the style attribute, a reference relationship between the XML element in the document storage structure and the style ID is established to represent the first XML style of the XML element through the style ID; for HTML elements with style tags, the style tags are converted into a second XML style defined under the document format standard; for HTML elements with both style attributes and style tags, the first XML style and the second XML style corresponding to the HTML element are merged to obtain the defined style corresponding to the HTML element, and the defined style is written to the corresponding position of the document storage structure.

[0107] Based on the document storage structure and document style structure, an XML document defined under the document format standard is generated.

[0108] Determine the area to be processed in the template document; replace the area to be processed with the document content of the XML document to obtain the target document.

[0109] In this embodiment, the HTML content filled in the rich text editor is converted into an HTML node tree, and according to the mapping relationship between HTML node tags and XML nodes defined under the document format standard, the HTML nodes are converted into nodes of XML document content, the style content in the node tag data is parsed, and the XML document style that complies with the document format standard definition is constructed, and the XML document is output according to the node content, and the XML document fragment is inserted into the tag placeholder position specified by the template document to achieve the output of the final target document.
