Automatic extraction algorithm and technical application of openXML document review records based on Python

This paper describes the composition of the OpenXML standard, DOCX composite XML file, and the application of regular expression and WORD document processing technology based on Python. It gives an algorithm scheme to extract and process WORD document comments automatically. The scheme can also extract the annotated content, such as text, pictures, visio charts, and tables. Facilitate the understanding of the comments made. Based on this scheme, software for automatically generating review reports is developed and applied to quality assurance work. At the same time, other document processing methods that follow OpenXML standards are introduced.
