Word macro to extract and save data between {tag}text data{/tag}

The project consists in coding a macro for Microsoft Word that would search in a .docx document any text data between tags such as {tag} ... {\tag} or {abstract} ... {\abstract} and record the text data as metadata of the .docx file under the label corresponding to the tag.
When several tags with the same label are found, the text data is appended to the text data previously recorded, separated by ";".
The expected deliverable of the project is the code of the macro.
