Description

Technical Field

[0001] This application relates to the field of document processing technology, and in particular to a method and apparatus for splitting and merging pptx files. Background Technology

[0002] When a team collaborates on a PowerPoint presentation, multiple roles typically divide the work and follow a workflow to complete the overall writing task. During the task, a task leader distributes the sections of the presentation to collaborators to write the content. Afterward, the team follows a workflow to merge the content, ensure consistency in style, polish, update, and manage the entire lifecycle of the document.

[0003] Currently, collaborative work on PPT documents is usually done offline: all participants have a local copy of the content they are responsible for, and they complete the writing, modification and updating work on their respective copies, which are then handed over to the person in charge for unified merging and management.

[0004] In offline collaboration, a single resource in a PowerPoint file may be shared by multiple PowerPoint slides. However, the resource is only associated with the initial slide where it first appears. Other slides that need to use the resource access the resource link from the initial slide. If the PowerPoint file is split, other slides may fail to access the resource, resulting in corruption of the split PowerPoint file. Summary of the Invention

[0023] If there are duplicate resources, one duplicate resource is retained, and the duplicate resource is inserted into the corresponding page according to the association relationship. The non-duplicate resources are also inserted into the corresponding pages. The association relationship refers to the correspondence between each page and the resources required by the page.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustration and has no specific meaning in itself. Therefore, "module" and "part" may be used interchangeably.

[0051] To address the problems mentioned in the background art, according to one aspect of the embodiments of this application, an embodiment of a method for splitting and merging pptx files is provided.

[0052] Optionally, in the embodiments of this application, the above-described method for splitting and merging .pptx files can be applied to, for example... Figure 1 The hardware environment shown consists of terminal 101 and server 103. Figure 1 As shown, server 103 is connected to terminal 101 via a network and can be used to provide services to the terminal. Database 105 can be set up on the server or independently of the server to provide data storage services for server 103. The network mentioned above includes, but is not limited to, wide area network, metropolitan area network or local area network. Terminal 101 includes, but is not limited to, PC, mobile phone, tablet computer, etc.

[0053] A method for splitting a pptx file in this embodiment can be executed by a terminal 101 or a server 103. The method for splitting a pptx file can be executed by the server 103 to enable lossless splitting and merging of pptx files.

[0054] The following will describe in detail a method for splitting and merging .pptx files provided in this application embodiment, with reference to specific implementation methods. Figure 2 As shown, the specific steps are as follows:

[0055] Step 201: Based on the tree-like organizational structure in the pptx file, parse the content of the pptx file and construct the relationship between each page and the resources required by the page.

[0056] The tree-like organizational structure indicates the way the content is organized in a .pptx file.

[0057] In this embodiment, a plugin is provided that can be inserted into application software such as PowerPoint or WPS to perform the following segmentation operation. The terminal obtains a .pptx file. The images, text, colors, and link resources in the .pptx file are presented in a tree structure (XML format). The terminal traverses the entire content of the .pptx file based on this tree structure, parses the resources required for each page, and constructs the association between each page and its required resources.

[0058] Each page may or may not have any resources. Resources refer to the resources used by the page, such as images, audio and video, links, etc. Resources are stored in the pptx file package.

[0059] Step 202: Upon receiving the splitting instruction, configure the corresponding resources for each split page according to the association relationship.

[0060] In this embodiment, when the terminal receives the splitting instruction, it splits the pptx file into multiple single pages. Since the resources corresponding to each page are already configured in the association relationship, the terminal can configure the corresponding resources for each split page according to the association relationship. That is, for the page that needs to be associated with resources, the corresponding resources exist in the pptx file package, and it is not necessary to call the links of other pages to obtain the resources.

[0061] Step 203: According to the preset configuration rules, construct at least one first sub-file based on the page after configuring resources, so that collaborators can modify the content of the first sub-file.

[0062] In this embodiment, the terminal determines the number of the first sub-files that need to be split. This number can be set according to the work content or the number of collaborators. This application does not impose any specific restrictions.

[0063] The terminal divides each page after configuring resources into at least one sub-file. That is, each page is divided into one first subfolder, or multiple first subfolders. Each first sub-file contains at least one page, thus obtaining at least one first sub-file. The first sub-file can be opened normally in various PPT authoring tools (such as PowerPoint, WPS, etc.) and can be edited by collaborators.

[0064] In this application, corresponding resources can be configured for the split pages without calling resources from other pages. Even if the pptx file is split into multiple first sub-files, each page can call the resources existing in the pptx file package without failure, thus avoiding damage caused by splitting the PPT file.

[0065] In addition, existing online collaboration technologies involve participants collaborating on the same cloud document online via a browser. Online collaboration is impossible without a network environment, and current online collaboration tools differ from everyday PPT writing tools (PowerPoint, WPS, etc.) in terms of capabilities and file formats, making them incompatible for use together.

[0066] Compared with existing technologies, this application can distribute the first sub-file to each collaborator for editing. Each collaborator can edit the content without using the network, and there will be no incompatibility issues between online collaboration tools and daily PPT writing tools.

[0067] Based on the same technical concept, this application also provides a method for merging .pptx files, applied to a server. The method includes: upon receiving a merge instruction, assembling multiple second sub-files according to a preset assembly order to obtain a target file, wherein the second sub-files are .pptx files whose content has been modified by collaborators; parsing whether there are duplicate resources in the target file; if there are duplicate resources, retaining one duplicate resource and inserting the duplicate resource into the corresponding page according to the association relationship, and inserting the non-duplicate resources into the corresponding page, wherein the association relationship refers to the correspondence between each page and the resources required by the page.

[0068] In this application, the collaborator edits the first sub-file using a terminal to obtain a modified second sub-file, which is then uploaded to the server. If the server needs to merge multiple second sub-files into a complete pptx file, it needs to sort the second sub-files according to the original order of the first sub-files within the pptx file to obtain the target file, which contains no duplicate pages.

[0069] In this scenario, different first sub-files may contain the same page, leading to situations where different collaborators edit the same page. When a collaborator uploads the edited second sub-file to the server, the same page will have different page versions on the server. This avoids the problem of version overwriting and loss of previous versions, allowing technicians to choose to download the required page version from the server.

[0070] Since multiple pages can reference the same resource, there's a possibility of resource duplication within the target file, meaning the resource appears multiple times. This can increase the file size of the target file. Therefore, the server needs to parse the resources in the target file to determine if there are duplicate resources.

[0071] If there are duplicate resources, for each duplicate resource, retain one of them and insert it into the corresponding page, while the others are deleted. The resource storage method remains the same as before the split: the first page to reference the resource calls it from the PPTX file package, and subsequent pages referencing the resource call the resource link from the first page that referenced it. For unique resources, insert them into the corresponding pages.

[0072] After sorting each second sub-file, the server inserts the resources into the corresponding page to generate a complete .pptx file that can be edited and used normally.

[0073] This application retains only one duplicate resource when merging PPTX documents, thus reducing the file size of the PPTX file.

[0074] Generating and parsing target files includes two implementation methods:

[0075] In one embodiment, each page in the target file corresponds to only one page version, and resources and pages correspond to each other; that is, each page corresponds to 0, 1, or more resources. The terminal determines each page in the second sub-file to be merged, sorts each page according to a preset assembly order, and obtains the target file.

[0076] The server identifies all resources corresponding to all pages of the target file, and then selects resources with the same attributes from these resources. Attributes refer to the unique identifiers of a resource, ensuring that these attributes remain unchanged even if a collaborator modifies the content of the resource. The server compares resources with the same attributes to determine if there are duplicates. This comparison can involve comparing resource space usage, image dimensions, video duration, etc. The comparison method for different resources can be determined based on the actual situation, and will not be elaborated upon in this application.

[0077] In another embodiment, each page in the target file corresponds to at least two page versions, and resources correspond to page versions, meaning that different page versions may correspond to the same or different resources. The server obtains multiple page versions of a page and selects one version (the selected version) for page sorting to obtain the target file; the server determines the resources corresponding to the target page of the selected version in the target file, and then selects resources with the same attributes from the target resources, compares the resources with the same attributes, and determines whether there are duplicate resources.

[0078] This application establishes a collaborative management method for PPTX that combines online and offline processes. It can support offline editing of the first sub-file and online automatic or manual merging and version management of the second sub-file.

[0079] When communicating between a terminal and a cloud server (e.g., transmitting slides), the encryption mechanism between the two parties is as follows: A (one of the terminal and the cloud server) sends n characters from its own identifier (which can be a device identifier or account; if this information is not binary encoded, it is converted to binary encoding) (if the i-th bit of its own identifier is 0, then the first n bits of its own identifier are taken; if the i-th bit of its own identifier is 1, then the last n bits of its own identifier are taken, where i is the integer part of the number of bits of the identifier divided by 2) and a preset string (stored by both the terminal and the cloud server, initially sent from the cloud server to the terminal, with a length of n). The terminal server periodically updates the timestamp (which is then XORed with the data). The result is converted to a decimal number j to determine the current timestamp. If the last digit of the timestamp is odd, the j-th encryption scheme in sequence is selected from the set of 2n-1 encryption schemes. If the last digit of the timestamp is not odd, the j-th encryption scheme in reverse order is selected from the set of encryption schemes. The selected encryption scheme is used to encrypt the target data, resulting in encrypted data. Then, the encrypted data, its own identifier, and the timestamp are used to form a data packet, which is sent to B (the other of the terminal and cloud servers). After receiving the data packet, B reads the timestamp and its own identifier and processes it in reverse order.

[0080] Based on the same technical concept, embodiments of this application also provide a device for splitting .pptx files, such as... Figure 3 As shown, the device includes:
