Hi Jürgen,

oolatex is not recommended way to use Tex4ht for the ODT conversion. It is better to use

make4ht -f odt mwe.tex

make4ht fixes some issues in ODT files and internal links are among them. Your example seems to work with make4ht.

hopefully updated in tl by now, closing.

I've added the hyperlink fixing filter to the make4ht ODT format. It is available on Github. It requires updated LuaXML library, where I fixed one critical issue.

When using \label{} and \ref{} (or \pageref{} in TeX, the opendocument output seems to be broken. The referenced Label is just not rendered visibly.

I've attached a MWE and the generated .odt file.

I'm using:

htxelatex test-labelref.tex "xhtml,ooffice" "ooffice/! -cmozhtf" "-coo -cvalidate"

to generated that file.
When running xelatex to generate a pdf file, everything works fine.

The TeX-Code line
<pre>
Something about Section \ref{sec:1} and --\ref{sec:2}-- to show something else on p.~\pageref{sec:1}.
</pre>

results in
<pre>
<!--l. 22--><text:p text:style-name="Text-body">Something about Section <t4htlink
href="#x1-10001">1<!--tex4ht:ref: sec:1 --></t4htlink> and &#x2013;<t4htlink
href="#x1-20002">2<!--tex4ht:ref: sec:2 --></t4htlink>&#x2013; to show something else on p.<text:s/><t4htlink
href="#x1-10001">3</t4htlink>.
</text:p>
</pre>

So, in summary, the reference is rendered, but not in the correct way. (Btw, shouldn't it be text:reference-ref instead of t4htlink? See http://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part1.html#element-text_reference-ref)

If you need any further information to reproduce the behaviour, please let me know.
