table of Contents
background
- When participating in the document modification of software design, you need to enter the data table in the docx document into the xml document. In the first entry, the entry of one field by one field is too troublesome, and there are dozens of fields. I can’t finish recording the table, so I want to use the code to read the corresponding table and generate the xml file from the data table.
- Of course, when writing a script, you may first think of writing it in Python. Since the Python environment is not installed on my computer, I used the existing environment to write Java code for conversion. When reading the table, there are still many problems that can be improved, but due to the different specifications of the documents, the processing is not very comprehensive, and now I will record what I have achieved.
DOCX data sheet
Table format one
Table format two
For the two formats of tables encountered, write code and generate corresponding xml files

There are still many imperfections in this table. For example, some fields of id, javaId and name of the table tag are not generated, and there will be time to deal with in the future.

to sum up
- Entering the docx data table into the xml, if the pure manual entry is a boring task, you will be dazzled if you are not careful.
- The implementation method is not very complete, and there are still many areas for improvement.
