Thanks for your response.
Here is what my application is doing
1. Uses aspose to convert docx file to doc
2. Uses another third party component to do html conversion of converted doc file
3. Passes both converted doc file and html to third component which then does analysis thes documents
This last components uses both doc and html file and has some algorithm which maps content of doc file to html. This component is failing because html do not have autogenerated numbers and doc does have it. I communicated with component which is doing html conversion and they told me that they are not able to have autogenerated numbers in html because those get generated only when you open document using word and they do not use word.
I am kind of stuck here, while coding I did see that you allow getting lists from documents but all those properties are readonly and I have no way to change them.
