It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0034] In addition, it should also be noted that in the technical solutions of the present application, the collected information is information and data authorized by the user or authorized by all parties, and the collection, storage, use, processing, transmission, provision, disclosure and application of related data are in accordance with relevant laws, regulations and standards of relevant countries and regions, necessary security measures are taken, public order and good customs are not violated, and appropriate operation portals are provided for users to choose authorization or refusal.

[0035] Figure 1 A flowchart of a text processing method according to an embodiment of the present application is provided. The present application can be applied to the case of leaving marks on changed content, especially to the case of leaving marks on changed content on the basis of a rich text editor. The method can be executed by a text processing device provided by an embodiment of the present application, which can be realized in the form of hardware and / or software and can be integrated into an electronic device carrying a text processing function, such as a server. As shown in FIG. 1, the method comprises: Figure 1

[0036] S110, obtaining the initial content of the rich text box in the rich text editor, and in response to the input operation of the user on the initial content, obtaining the changed content.

[0037] The initial content is the content input by the relevant personnel in the rich text box of the rich text editor, which can be the first input content or the last version of the input end. The present application does not make specific limitation on this. The input operation is the operation of re-editing the last input content in the rich text box, which can include deletion, change or addition of the initial content. The changed content is the content after the initial content is changed.

[0038] Specifically, the initial content of the rich text box in the rich text editor is obtained. The user can perform input operations such as deletion, change or addition on the initial content through the rich text box. In response to the input operation of the user, the content of the initial content changed by the user is obtained. ​

[0039] S120, simplifying the initial content and the changed content to obtain an initial array and a changed array.

[0040] The simplifying can be converting the content into an operable DOM (Document Object Model) document object model; the initial array is an array obtained by simplifying the initial content, and the initial array includes text content and multimedia files; and the changed array is an array obtained by simplifying the changed content, and the changed array includes changed text content and multimedia files.

[0041] Specifically, the string of the initial content is converted to obtain a corresponding DOM object, and the text, multimedia or table in each node is extracted to obtain a corresponding initial array; the string of the changed content is converted to obtain a corresponding DOM object, and the text, multimedia or table in each node is extracted to obtain a corresponding changed array.

[0042] It can be understood that the content input in the rich text box in the rich text editor has various styles, such as different fonts, colors and font sizes; and in simple text comparison, the change of the text style does not need to be concerned, so the rich text content is simplified to remove the font, color and other styles before the content difference comparison, to avoid the influence of the styles and further improve the efficiency of the subsequent difference content comparison.

[0043] S130, comparing the initial array and the changed array to obtain a target difference array.

[0044] The target difference array is the difference content of the initial array and the changed array; and includes deleted, newly added or unchanged text content or multimedia files.

[0045] Specifically, the simplified initial array and the changed array are compared to obtain a difference content object array.

[0046] S140, processing the target difference array to obtain target difference prompt content.

[0047] The target difference prompt content is content with a difference change prompt; and the difference change prompt can be content with a deleted content prompt.

[0048] Specifically, the target difference array is processed to obtain content with a deleted content prompt.

[0049] In an optional mode of the present application, the difference content in the target difference array can be deleted content or newly added content, and the deleted content can be prompted and displayed as the target difference prompt content.

[0050] It can be understood that after the content in the rich text box is deleted, the relevant record or trace is still retained, so as to be tracked or recovered subsequently.

[0051] S150, display the target difference prompt content in the rich text editor.

[0052] Specifically, after obtaining the target difference prompt content, the difference prompt content can be displayed in the rich text editor, so as to retain the change record or trace.

[0053] Optionally, the initial content and the change content of the rich text box are HTML files.

[0054] Specifically, the rich text in the rich text editor is with HTML format, and during editing, tables or multimedia pictures and videos can be added or deleted, so that the simple text comparison tool cannot compare on the basis of the format.

[0055] It can be understood that, since the existing text comparison tool cannot compare the HTML files in the rich text, the embodiment of the present application can quickly compare the differences between the content before and after the change of the rich text box by converting the initial content and the change content of the rich text box into an array form through string conversion.

[0056] The embodiment of the present application obtains the initial content of the rich text box in the rich text editor, and in response to the input operation of the user on the initial content, obtains the change content; simplifies the initial content and the change content to obtain an initial array and a change array; compares the initial array and the change array to obtain a target difference array; processes the target difference array to obtain target difference prompt content; and displays the target difference prompt content in the rich text editor. The above technical solution compares the initial content and the change content in the rich text editor through simplification processing, obtains a difference array, and then completes the display of the difference content, thereby avoiding the problem that the simple text comparison tool cannot compare on the basis of the format, and realizing that after editing the rich text in the existing rich text editor, the relevant record or trace is still retained, so as to facilitate subsequent tracking or recovery.

[0057] Figure 2 is a flowchart of a text processing method according to the embodiment of the present application. The embodiment of the present application supplements the initial array and the change array obtained by simplifying the initial content and the change content on the basis of the above embodiment. It should be noted that, for the parts not described in detail in the embodiment of the present application, reference can be made to the relevant descriptions of other embodiments, such as Figure 2 The method comprises the following steps:

[0058] S210, obtaining the initial content of the rich text box in the rich text editor, and in response to the input operation of the user on the initial content, obtaining the change content.

[0059] S220. Convert the initial content and the changed content into DoM objects respectively; the DoM object includes a first object and a second object.

[0060] The DOM object includes a first object and a second object; the first object is the DOM object transformed from the initial content; the second object is the DOM object transformed from the changed content.

[0061] Specifically, by using the API provided by the rich text box to obtain the initial content string and the changed content string, you can use the browser's built-in DOMParser to create a DOMParser instance, convert the initial content string into a first object, and the changed content string into a second object.

[0062] S230. Recursively extract the node content of all nodes in the DoM object; the nodes include the first node and the second node, and the node content includes the first content and the second content.

[0063] The node content may include text content, multimedia file content, or table content; the first node is the node in the first object corresponding to the initial content; the first content is the content corresponding to the first node; the second node is the node in the second object corresponding to the changed content; and the second content is the content corresponding to the second node.

[0064] Specifically, a function can be defined to recursively extract the node content from the DOM object; obtain the first content corresponding to the first node in the first object; and the second content corresponding to the second node in the second object.

[0065] S240. Obtain the initial array and the changed array based on the node's attribute values ​​and node content.

[0066] The attribute values ​​of a node describe its content type. For example, a text node has an attribute value of 3, while a multimedia node is an element node with an attribute value of 1. The node content can be text content or multimedia files.

[0067] Specifically, the content of each node is extracted based on its attribute values. Text content is extracted from text nodes, and multimedia files are extracted from multimedia nodes. The extracted text content and multimedia files are then assembled in sequence to obtain the corresponding initial array and change array.

[0068] Optional, such as Figure 3 The method shown obtains an initial array and a changed array based on the node's attribute values ​​and node content, including:

[0069] S241, judging whether the node is a text node based on the attribute value of the node, if yes, extracting the text of the node content as a target text; the target text includes a first target text and a second target text.

[0070] Wherein, the attribute value of the text node is 3; the first target text is the text content in the initial content; the second target text is the text content in the changed content.

[0071] Specifically, the node type in the first content is traversed, if the attribute of the node is 3, it indicates that it is a text node, and the text content in the node is extracted as the first target text; the node type in the second content is traversed, and the text node is judged based on the attribute value of the node, if it indicates that it is a text node, the text content in the node is extracted as the second target text.

[0072] S242, if the node is not a text node, judging whether the node is a multimedia file based on the attribute value of the node, if yes, encoding the multimedia corresponding to the node to obtain a multimedia array; the multimedia array includes a first multimedia array and a second multimedia array.

[0073] Wherein, the attribute value of the multimedia node is 1; the first multimedia array is the multimedia file in the initial content; the second multimedia array is the multimedia file in the changed content.

[0074] Specifically, if the first content is not a text node based on the attribute value of the node, it is further judged whether the node is a multimedia file node, if yes, the file is encoded and stored in an array format to obtain the first multimedia array; if the second content is not a text node based on the attribute value of the node, it is further judged whether the node is a multimedia file node, if yes, the file is encoded and stored in an array format to obtain the second multimedia array.

[0075] In an optional mode of the present application, the multimedia file can be converted into base64 encoding and stored in an array format, and replaced with N is an array index.

[0076] It can be understood that, by encoding conversion of multimedia files with array storage, and replacing nodes with N is an array subscript, ensuring the order of each multimedia file in the multimedia array, and improving the efficiency of subsequent multimedia difference comparison.

[0077] S243, if the node is not a multimedia file, replacing the node type of the node with a specific mark type based on a preset node type replacement strategy; the specific mark type includes a first specific mark type and a second specific mark type.

[0078] The node type replacement strategy is a preset node type replacement strategy; for example, DIV and P tags are replaced with <l>< / l> , TABLE is replaced with <t>< / t> , TR is replaced with <r>< / r> , TD is replaced with <d>< / d> , and TBODY is replaced with The first specific mark type is the specific mark type of each node in the initial content; and the second specific mark type is the specific mark type of each node in the changed content.

[0079] Specifically, if the node in the first content is also not a multimedia file node, the node type mark of the node is replaced with the first specific mark type based on the preset node type replacement strategy; and if the node in the second content is also not a multimedia file node, the node type mark of the node is replaced with the second specific mark type based on the preset node type replacement strategy.

[0080] In an optional mode of the present application, after the node type of the node is replaced with the specific mark type based on the preset node type replacement strategy, the method further includes: traversing all the child nodes in the DOM object again, and judging the node content of the node attribute of each node in the specific mark type until all the child nodes are judged.

[0081] It can be understood that by replacing the node type mark, the efficiency of node traversal is improved, and the array corresponding to the node content is quickly obtained; and the subsequent comparison efficiency is further improved.

[0082] S244, the target text, the multimedia array and the target mark type are assembled in order respectively to obtain an initial array and a changed array.

[0083] Specifically, the first target text, the first multimedia array and the first target mark type are assembled in order to obtain a text string and a multimedia file array as an initial array; and the second target text, the second multimedia array and the second target mark type are assembled in order to obtain a text string and a multimedia file array as a changed array.

[0084] It can be understood that the initial content and the change content are converted into DOM objects respectively, and the initial array and the change array are obtained by traversing each node to extract the node content, which simplifies the rich text content, removes the font, color and other styles, and retains the paragraph, table, picture and other contrast content; and the subsequent comparison efficiency is improved.

[0085] S250, comparing the initial array and the change array to obtain a target difference array.

[0086] Optionally, as shown in a target difference array determination method, the initial array and the change array are compared to obtain a target difference array, including: Figure 4

[0087] S251, comparing the node types of the initial array and the change array based on the initial array and the change array to obtain an initial difference array.

[0088] The node types include text nodes and multimedia nodes; and the initial difference array is a difference content object array in the initial array and the change array.

[0089] Specifically, the initial array and the change array are compared based on the node types; for example, the text nodes are compared using diff_match_patch to obtain difference text content; the multimedia array is compared in sequence to obtain a difference multimedia array; and the difference text content and the difference multimedia array are assembled in sequence to obtain the initial difference array.

[0090] S252, recording the node state of the node based on the change attribute of each node in the initial difference array to obtain a target difference array; the node state includes an unchanged state, a deletion state or an addition state.

[0091] The change attribute is addition, deletion or unchanged; and the target difference array is a difference array containing each node state.

[0092] Specifically, the node state of the node is recorded based on the change attribute of each node in the initial difference array, and each node state includes an unchanged state, a deletion state or an addition state; and the target difference array is obtained.

[0093] It can be understood that the difference array is recorded based on the node type and the change attribute of the node to obtain a changed array, so that the system still retains relevant records or traces after the change operation, facilitating subsequent tracking or recovery.

[0094] S260, processing the target difference array to obtain target difference prompt content.

[0095] Optionally, the target difference array is processed to obtain target difference prompt content, including:

[0096] ​Traverse the node state of each node in the target difference array, and take the node with a deletion state as an initial node;

[0097] Obtain a specific flag type of other nodes in the target difference array except text and multimedia nodes;

[0098] Split the initial node according to the specific flag type to obtain each subtext;

[0099] Splice each subtext with a deletion line to obtain a target node;

[0100] Splice the target node into the target difference array to obtain an initial difference prompt array;

[0101] Restore each target flag type in the initial difference prompt array based on a preset node type replacement strategy to obtain a target difference prompt content.

[0102] Among them, the initial node is a node with deleted content; the initial difference prompt array is an array with difference prompt content; and the target difference prompt content is content with deletion prompt.

[0103] Specifically, traverse the difference content array, judge whether it is a deletion state node based on the node state, if yes, take the node with a deletion state as an initial node; split the content of the deletion node according to the flag defined by the specific flag type to obtain each subtext, such as <t b r l d>, will each segment of subtext using added strikethrough target node, will the target node splicing to the target difference array array to get the initial difference prompt, and after splicing processing results, the results of the text in a specific simple <t b r l d>The label mark is further reduced to a specific label, and the multimedia file is further reduced, so that the target difference prompt content with the deleted content prompt is obtained.

[0104] In an optional mode of the present application, each subtext is added with a deletion line, which can be wrapping each subtext with <delstyle="color:red">he to obtain a target node, and obtaining an initial difference prompt array by splicing back the target difference array, and the content obtained by reducing the initial difference prompt array is the deleted content with the deletion line.

[0105] It can be understood that by adding a deletion line to the difference text node, it is possible to support recording and identifying whether the rich text content is deleted, so that the system still retains relevant records or traces after the deletion operation, and supports subsequent tracking or recovery of relevant users.

[0106] S270, displaying the target difference prompt content in the rich text editor.

[0107] The embodiment of the present application converts the initial content and the changed content to obtain a DOM document object type, obtains a difference array based on the change state of each node, and further adds a deletion line to the difference node in the deletion state, so that the system still retains relevant records or traces, and relevant technical personnel can see the deleted records, so as to prevent necessary content from being deleted, for example, a customer manager deletes some risk prompt content in a product introduction, and if the approver does not discover it in time, this material will cause bad consequences in the future, and the trace of the deleted content in the rich text editor is realized.

[0108] Figure 5 It is a structure schematic diagram of a text processing device provided by the embodiment of the present application. The present application can be applied to the case of leaving traces of changed content, especially to the case of leaving traces of changed content based on a rich text editor. The text processing device can be realized in the form of hardware and / or software, and can be integrated in an electronic device carrying a text processing function, such as a server.

[0109] The acquisition module 310 is used to acquire the initial content of the rich text box in the rich text editor, and acquire the changed content in response to the input operation of the user on the initial content.

[0110] The simplification processing module 320 is used to simplify the initial content and the changed content to obtain an initial array and a changed array.

[0111] The comparison module 330 is used to compare the initial array and the changed array to obtain a target difference array.

The initial array and the changed array are obtained by simplifying the initial content and the changed content. The target difference array is obtained by comparing the initial array and the changed array. The target difference prompt content is obtained by processing the target difference array. The target difference prompt content is displayed in the rich text editor. The above technical solution obtains the difference array by comparing the initial content and the changed content in the rich text editor, and then displays the difference content, thereby avoiding the problem that the simple text comparison tool cannot compare the content with format, and realizing that the relevant record or trace is still retained after the editing operation on the rich text in the existing rich text editor, so as to facilitate subsequent tracking or recovery.
