Creating too many NumberingInstances for unordered lists #46

Closed BenGraf closed 5 years ago

BenGraf commented 5 years ago

Im composing a large OpenXML document from many HTML fragments, that contain lots of unorderd lists. It seems html2openxml appends a new NumberingInstance for each opening tag (<ul>), which might be correct, but more than really necessary. I'm facing an issue with Microsoft-Word, when trying to open the document, because it cannot cope with the thousands of NumberingInstances (showing an "out of memory" error.) I already tried to tweak HtmlToOpenXml.NumberingListStyleCollection.BeginList() to create only one NumberingInstance per nesting level, but ended in messing up the numbered lists.

I suggested a pull-request #53 that solved the issue for me.
