Can open office convert an docx xml file into html

Can open office convert an docx xml file into html

I have a web application that converts microsoft word documents to html
using LibreOffice. Everything has been working great, but I am having some
issues with their ability to interpret indentation on certain files.
Using suggestions from other kind developers, I have discovered how to
pull apart the docx file by converting it to a zip, unzipping it, and then
extracting the document.xml file. in the process, I have noticed that
LibreOffice is consistently incapable of interpreting any <w:tab> tags and
rendering them as indentations.
I have tried many things to fix this, but I am running out of ideas. My
last ditch effort was going to be to use php to programatically replace
all of the <w:tab> tags with <w:ind> tags (which LibreOffice successfully
interprets as tabs). However, as soon as i convert the file to .zip with
bash I am unable to seal it back up as a docx. I mean, i can do it, but
LibreOffice no longer recognizes it and throws a strange error at me.
Is there any way I can get an html rendering from just pulling the
document.xml file? If not, does anybody know how to seal these documents
back up again? Any help is much appreciated. Thanks!
