[tex4ht] Problem with hyperref

[Milanese Guido Fabrizio]

Thank you for your kind and useful suggestions. Yes, I did know the excellent Markdown package, but I am a bit rigid in my habit of keeping formats "separated". Digging in the pandoc usergroup  archive I found the easiest solution: call the filter as  -f --markdown-auto_identifiers 

See:

pandoc -f markdown-auto_identifiers+smart file.md  -t latex+smart -s -o file.tex

As an excuse, I must say that the manual is (at leas tome) not particularly clear about this issue.

Best regards and wishes for Christmas and the New Year.

Dear Guido,

you may also try the Markdown package, it enables direct Markdown
support in TeX and it works quite well with tex4ht. It also supports
mixing Markdown and LaTeX macros, so you can use all the Markdown
shortcuts for basic formatting and use LaTeX for more advanced stuff.

Back to your actual question:

It is definitely not a bug or a mistake on your side. The problem is
that the \hypertarget command inserts the opening link, which starts a
new paragraph. But the \section command closes this paragraph, which
leaved this opening link unclosed. After the end of section command, new
paragraph is started and the link is closed. This produces an invalid
XML structure, which causes the post-processing to fail.

You may try to use a following macro in a config file:

\def\hypertarget#1#2{\ifvmode\IgnorePar\EndP\fi\Link{}{#1}#2\ifvmode\IgnorePar\EndP\fi\EndLink}

This definition tries to insert the link outside of a paragraph, so the
XML is at least well-formed. It seems that the LibreOffice can open the
resulting file, so it seems to work somehow. This definition cannot be used
for HTML, because the code it produces is non-valid.

I also don't particularly like the \hypertarget use here. Why Pandoc
doesn't use only \label?

I think you may really like the Markdown package then.
