eLyXer is a standalone LyX to HTML converter. In the resulting file, equations are formatted as MathML, and the file itself starts with an XML tag.
This causes two problems:
- LibreOffice does not read the XML file (it can read HTML files, but not XHTML).
- I am unable to copy and paste the equations into a document editor such as LibreOffice with the goal of subsequent conversion into .doc, because .doc files do not support MathML.
The eLyXer help page mentions an option to only use simple math, but there is no option to set math equations to output as images. And I already set Document > Settings > Output > Math equations > Format: images in LyX, which presumably is saved in the lyx document somewhere.
A web search did not come up with any solutions.
