摘要：【中文】本发明提供一种PowerPoint文件的文字提取方法、系统、终端及存储介质，包括：从PowerPoint Document数据流筛选出文字标签；通过遍历文字标签的子标签类型筛选出文字子标签；从所述文字子标签提取数据，并将所述数据转换为文字段；将从所有文字标签提取出的多个文字段进行汇总拼接，拼接完成后得到文字文件。本发明提供的方法兼容性好，不依赖Office PowerPoint/金山Dps组件，无需安装Office或者提取Office组件文件，纯粹调用系统API函数。效率高，二进制读取文件，并进行精确定位处理，执行效率显著提高。程序包小，所有实现通过自己手动编码和调用系统API函数，不依赖任何第三方程序文件。 【EN】The invention provides a method, a system, a terminal and a storage medium for extracting characters of a PowerPoint file, wherein the method comprises the following steps: screening out text labels from the PowerPoint Document data stream; screening out character sub-labels by traversing the sub-label types of the character labels; extracting data from the text sub-label and converting the data into text fields; and summarizing and splicing a plurality of text fields extracted from all text labels to obtain a text file after splicing. The method provided by the invention has good compatibility, does not depend on the Office PowerPoint/Jinshan Dps component, does not need to install Office or extract the Office component file, and purely calls the system API function. The efficiency is high, the binary system reads the file and carries out accurate positioning processing, and the execution efficiency is obviously improved. The program package is small, all the realization is through oneself manual coding and calling system API function, does not rely on any third party program file.

摘要：【中文】本发明提供了一种解析Office二进制格式并提取文档属性文字的方法及系统，本发明通过分析Office文档的二进制数据，根据文档中属性的存放原理，将Office文档中的属性文字全部提取出来，相对于使用二次接口开发和JAVA OPI技术接口提取文档属性中的文字，通过分析二进制文件并提取文件属性中文字可支持跨平台，不仅支持Windows系统而且支持Linux等系统，且效率高，通过二进制读取文件，并进行精确定位处理，执行效率显著提高，另外程序包小，所有实现均通过手动编码和调用系统API函数，不依赖任何第三方程序文件。本发明不限制于Office文件的文字提取，凡是采用Office存放原理的文件都可采用此方法提取文字，如金山Office等。 【EN】The invention provides a method and a system for analyzing an Office binary format and extracting document attribute characters, wherein the method and the system are characterized in that binary data of an Office document are analyzed, the attribute characters in the Office document are all extracted according to the storage principle of the attributes in the document, and compared with the method for extracting the characters in the document attributes by using secondary interface development and JAVA OPI technical interface, cross-platform can be supported by analyzing a binary file and extracting the characters in the document attributes, a Windows system and a Linux system are supported, the efficiency is high, the file is read by the binary system and is accurately positioned, the execution efficiency is obviously improved, in addition, the program package is small, all the realization is realized by manually coding and calling the system API function, and no third-party program file is relied. The invention is not limited to the character extraction of Office files, and all files adopting the Office storage principle can be extracted by adopting the method, such as Jinshan Office and the like.
