These accompanying drawings and the written description are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different accompanying drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0025] When it is difficult to view the original data due to the XML file containing structured data, and the data needs to be stored in an uneditable format for a long time, it becomes necessary to convert the XML file into a PDF file.

[0026] Currently, in the related technical fields, the conversion operation from XML files to PDF files usually relies on manual work. However, this method is less efficient, especially when dealing with a large number of XML files, which requires a long time.

[0027] To address the above technical problems, the inventor proposed the following technical concept: By using the template selected by the user, read the corresponding data in the XML file according to the template content, and input the data into the PDF file in the format required by the template file to complete the conversion from the XML file to the PDF file.

[0028] This application is applied to the scenario of file format conversion. It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. And the collection, use, and processing of relevant data need to comply with relevant laws, regulations, and standards, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0029] Figure 1 It is a schematic diagram of the scenario of the file format conversion method provided by this application. As Figure 1 , in this scenario, it includes: a terminal device 101.

[0030] In the specific implementation process, the terminal device 101 can include a computer, a server, a tablet, a mobile phone, a personal digital assistant (PDA), a notebook, etc. They can perform data input, file reading, downloading data from the network, and format conversion, etc.

[0031] The terminal device 101 is used to obtain the XML file from the local or network using at least one thread, and convert the XML file using the template required by the user to obtain a PDF file.

[0032] It can be understood that the scenario illustrated in the embodiments of this application does not constitute a specific limitation on the file format conversion method. In some other feasible embodiments of this application, the above scenario may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or different component arrangements, which can be specifically determined according to the actual application scenario and are not limited here. Figure 1 The shown scenario can be implemented by hardware, software, or a combination of software and hardware.

[0033] The technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail below with specific embodiments. The following several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0034] Figure 2 It is a schematic flowchart of the file format conversion method provided by the embodiments of the present application. The execution subject of the embodiments of the present application can be Figure 1 the terminal device in, or a server, etc., and this embodiment does not make special restrictions on this. As Figure 2 shown, the method includes:

[0035] S201: Obtain at least one Extensible Markup Language file.

[0036] In this step, it may include reading the XML file from a preset position in the storage unit of the terminal device itself, or may include calling an interface to obtain the XML file returned by the interface, and may also include detecting the XML file selected by the user through dragging, selecting, etc.

[0037] S202: In response to detecting the template identifier input by the user, read the conversion parameter template corresponding to the template identifier.

[0038] In this step, it may include detecting the template identifier input by the user in the input box, or may include detecting the template file selected or chosen by the user.

[0039] Among them, the template identifier may include a template code, a template name, etc.

[0040] S203: Read the data source and output format in the conversion parameter template.

[0041] In this step, it may include reading the data within the preset tags to obtain the data source and output format, or may include reading the data after the data source field in the conversion parameter template to obtain the data source, and reading the content after each output format field to obtain the output format.

[0042] S204: Use at least one thread to read the target data corresponding to the data source in the Extensible Markup Language file.

[0043] In this step, the data source may include HTML (Hyper Text Markup Language) tags, and the target data is obtained by reading the content of the HTML tags.

[0044] S205: Generate a Portable Document Format file that conforms to the output format using the target data.

[0045] In this step, it includes writing the target data into a blank PDF file in the output format to obtain a Portable Document Format file that conforms to the output format.

[0046] As can be seen from the description of the above embodiments, the embodiments of the present disclosure obtain an XML file and use at least one thread to read and write data according to the template required by the user, automatically converting the XML file into a PDF file, increasing the conversion speed. And since multiple threads can be used to perform format conversion simultaneously, the blocking time of input / output operations is reduced, thus improving the format conversion speed. In addition, since the template can be customized by the user, supporting custom layout, style, and content structure, the generated PDF has a neater appearance.

[0047] In a possible implementation manner, in the above step S204, using at least one thread to read the target data corresponding to the data source in the Extensible Markup Language file includes: step S204A1 and step S204A2.

[0048] S204A1: Obtain the number of Extensible Markup Language files.

[0049] In this step, for example, if 3 Extensible Markup Language files are read from a preset location, the number of Extensible Markup Language files is 3. Another example is that when periodically obtaining XML files from a preset interface, 10 Extensible Markup Language files are obtained from the preset interface, then the number of Extensible Markup Language files is 10.

[0050] S204A2: Use a thread greater than or equal to the number of Extensible Markup Language files to read the target data corresponding to the data source in the Extensible Markup Language file.

[0051] In this step, for example, if the number of obtained Extensible Markup Language files is 3, then 3 or 6 threads are used to read the target data corresponding to the data source in the Extensible Markup Language file. Another example is that if the number of obtained Extensible Markup Language files is 5, then 5, 10, or 15 threads are used to read the target data corresponding to the data source in the Extensible Markup Language file.

[0052] As can be seen from the description of the above embodiments, the embodiments of the present disclosure read the data in the Extensible Markup Language file using a thread greater than or equal to the number of Extensible Markup Language files, realizing the simultaneous reading of the content in multiple XML files and increasing the file conversion speed.

[0053] In a possible implementation manner, in the above step S204, using at least one thread to read the target data corresponding to the data source in the Extensible Markup Language file includes: step S204B1 and step S204B2.

[0054] S204B1: Map the Extensible Markup Language file to a target object using at least one thread.

[0055] In this step, it may include mapping the Extensible Markup Language file to a target object using the same number of threads as the number of Extensible Markup Language files. Each thread can use the JAXB tool to map the Extensible Markup Language file to a target object.

[0056] Among them, the target object can be preset by the staff or user. For example, a Book object or any other preset object.

[0057] S204B2: Read the target data corresponding to the data source in the target object.

[0058] In this step, a preset parser can be used to parse the target object to obtain the target data corresponding to the data source in the target object.

[0059] Among them, the preset parser is, for example, a Jsoup parser. The target data can include text, images, etc.

[0060] As can be seen from the description of the above embodiments, the embodiments of the present disclosure map the XML file to a target object by using at least one thread, so as to be able to read the target data corresponding to the data source from the target object. Since multiple threads can be used for processing simultaneously, the data reading speed is increased. And since the XML is mapped to a target object, the subsequent processes of data reading and data processing are more convenient, the data processing speed is increased, and it is convenient for subsequent data reuse.

[0061] In a possible implementation manner, the above step S205 uses the target data to generate a Portable Document Format file that conforms to the output format, including: step S2051 and step S2052.

[0062] S2051: If the target data includes text content, write the text content into the Portable Document Format file.

[0063] In this step, it may include writing the text content into the Portable Document Format file line by line. If the text content is segmented, the text content can be written into the Portable Document Format file in segments.

[0064] S2052: Set the format of the text content in the Portable Document Format file according to the output format.

[0065] In this step, it may include setting the format of the Portable Document Format file according to the font, line spacing, font size, page margin, etc. required by the output format.

[0066] As can be seen from the description of the above embodiments, the embodiments of the present disclosure make the obtained PDF file meet the requirements of the parameter template by writing text content into the PDF file and adjusting the format to meet the requirements of the output format in the template.

[0067] In a possible implementation manner, in step S205 above, generating a portable file format file that meets the output format using the target data includes steps S2053 to S2056.

[0068] S2053: If the target data includes a picture, obtain the size of the picture.

[0069] In this step, obtaining the size of the picture includes obtaining the length and width of the picture.

[0070] Among them, the picture can be a picture in any format.

[0071] S2054: Obtain the remaining space size of the portable file format file.

[0072] In this step, the remaining space size of the portable file format file can be obtained by using a preset plug-in or program method.

[0073] S2055: If the size of the picture is greater than the remaining space size, reduce the size of the picture to obtain a reduced image.

[0074] In this step, the method of reducing the size of the picture can include dividing the remaining space size by the picture size to obtain a reduction ratio, and reducing both the length and width of the picture according to the reduction ratio to obtain a reduced image.

[0075] For example, if the length of the picture is 1200 and the remaining space size is 800, then reduce the length of the picture to 800 and reduce the width of the picture proportionally to obtain a reduced image. Another example, if the length of the picture is 1500 and the remaining space size is 500, then calculate the reduction ratio as one-third, and reduce both the length and width of the picture to one-third to obtain a reduced image.

[0076] S2056: Write the reduced image into the portable file format file.

[0077] In this step, it can include writing the reduced image into the remaining space of the portable file format file. It can also include converting the reduced image to a color space supported by PDF, adjusting the resolution of the reduced image according to the output format, compressing, creating a stream object in the PDF, and making a stream reference in the content stream of the PDF page.

[0078] As can be seen from the description of the above embodiments, when the remaining space size of the PDF page is not enough to write the picture, the picture is reduced and then written to ensure that the picture is not displayed on multiple pages and is not truncated.

[0079] In a possible implementation, after obtaining the remaining space size of the portable document format file in step S2054 above, the following is further included:

[0080] S2057: If the remaining space size is less than the preset space size, a new page is created in the portable document format file, and the picture is written to the newly created page.

[0081] In this step, a new page is created by at least one of creating a new page object, updating the page tree, creating a content stream, updating the page tree, and associating it with the PDF document root directory. The process of writing the picture to the newly created page is similar to step S2056 above and will not be elaborated here.

[0082] As can be seen from the description of the above embodiments, the embodiments of the present disclosure directly create a new page when the remaining space size is less than the preset space size, and write the picture to the newly created page, so as to avoid the picture being displayed on multiple pages or being truncated.

[0083] In a possible implementation, after generating a portable document format file that conforms to the output format using the target data in step S205 above, the following is further included:

[0084] S210: Add a preset electronic seal picture to the portable document format file.

[0085] In this step, it includes referring to the electronic seal picture in the page content stream and drawing the electronic seal picture to a preset position on the page or the position required by the parameter template.

[0086] As can be seen from the description of the above embodiments, the embodiments of the present disclosure add an electronic seal picture to the generated PDF file, thereby increasing the reliability of the PDF document.
