Drawings
Fig. 1 is a block diagram illustrating steps of a method for online editing of a presentation according to an embodiment of the present invention.
Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
In order to overcome the problems in the prior art, the invention provides an online editing method for a presentation, which can be used for online editing of a PPT file on an HTML webpage.
Fig. 1 is a block diagram illustrating steps of a method for online editing of a presentation according to an embodiment of the present invention.
In step S1, a PPT file is acquired: and when an editing request is received, acquiring the PPT file which is stored by the user from the hard disk of the server.
Format conversion of the PPT file is performed in step S2: and decompressing the PPT file through the open source program POI, and storing the PPT file as a file in an XML format.
The XML-formatted file is parsed in step S3. Optionally, the XML-formatted file is parsed by using an open-source XML parsing package DOM 4J.
The tag meaning is determined in step S4: and comparing each label in the XML-format file with a PPT label library so as to determine the meaning of each label in the XML-format file.
The conversion of the label is performed in step S5: and converting each label in the XML-format file into a corresponding HTML label according to the meaning of each label in the XML-format file. Specifically, the HTML tag is an SVG tag in an HTML page. For example, the < a: prstGeom prst ═ rect > tag in XML is compared by a PPT tag library, and the meaning of the tag is determined to be 'a rectangle', and then the XML tag is converted into the < rect > tag of SVG in HTML.
Preferably, a multithreading asynchronous simultaneous parsing method can be adopted to convert each tag in the XML-format file into a corresponding HTML tag, so that the parsing of the file can be accelerated, and even if the PPT file is too large, the parsing can be completed quickly; the method and the device can be quickly presented on the page, and the user experience quality is improved.
Preferably, the custom attribute is set in the HTML tag in step S6. For example, an ap attribute is added to the < rect > tag of a paragraph in HTML for use in save after editing, which may indicate the location modified by the user after editing.
Through the implementation mode, the PPT file is converted into the form which can be edited by the HTML page, and a user can edit the HTML page on line.
Preferably, in an embodiment, after the user finishes editing the contents of the PPT file on the browser, the online editing method for the presentation further includes: after receiving a storage request, converting an HTML source code of the edited PPT file into an XML format, and inquiring the custom attribute so as to obtain a modification position of the PPT file; updating the XML format file; reading the updated XML-format file through the open source program POI and converting the XML-format file into a PPT file; and storing the PPT file into a hard disk of the server.
Based on the same inventive concept, the present invention further provides an electronic device, which includes a memory, a processor, and a computer program stored in the memory and running on the processor, wherein the processor executes the computer program to implement the steps of the method according to any of the above embodiments.
Based on the same inventive concept, the present invention also provides a non-transitory computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, implements the steps of the method according to any of the above embodiments.
In summary, according to the online editing method for the presentation and the electronic device in the embodiment, the PPT file can be edited online on the HTML webpage, and the method can be deployed in operating systems such as Windows, linux, android and the like without modifying any code, and is easy to implement and maintain. In addition, according to the method, a user does not need to install Office software in a local or server, the user can open a webpage as long as the Internet exists, the PPT file of the user can be directly checked and edited, and the PPT file is stored in the cloud in real time, so that the method has extremely high convenience.
