XML-processing: Error with hyphenatedurl

27 Oct 2021

      Hi,

I've receiving errors that seem to be related to hyphenatedurl. The problem is I cannot really reproduce it in a MWE. The example below works, but if I include the link in my real document, I'am getting this error message (copied from -error.log):

%%%%%%%%%%%%%%%%%%%%%
return {
["errortype"]=1,
["filename"]="",
["lastcontext"]="\n<to be read again> \n    \n    \\xdeffile://xdef \n<macro> \\expandedfile://expanded \n    #1->\\xdeffile://xdef \n    \\m_syst_helpers_expandedfile://m_syst_helpers_expanded {\\noexpand #1}\\m_syst_helpers_expanded \n<macro> \\22>:xml:ext-linkfile://22%3e:xml:ext-link \n    #1->\\begingroupfile://begingroup \\expandUxfile://expandUx \\expandedfile://expanded \n    {\\goto {\\hyphenatedurl {\\xmlflush {#1}}}[url(\\xmlflushfile://xmlflush {#1})]}\\endgroup \n<lua output> \n<macro> \\22>:xml:pfile://22%3e:xml:p \n    #1->\\begingroupfile://begingroup \\xmlfilterfile://xmlfilter {#1}{.[@xml:lang]/command(xml:language)}\\xmlflush {#1}\n    \\endgroupfile://endgroup \\parfile://par \n<lua output> \n ...\n\n<initial> \n    \n\n",
["lastluaerror"]="",
["lasttexerror"]="Missing number, treated as zero",
["lasttexhelp"]="A number should have been here; I inserted '0'. (If you can't figure out why I\nneeded to see a number, look up 'weird error' in the index to The TeXbook.)",
["linenumber"]=9,
["offset"]=10,
["skiplinenumber"]=5,
}

Two things seemed to make it work:
1. Remove the link.
2. Comment out \expandUx in this setup:

%%%%%%%%%%%%%%%%%%%%
\startxmlsetups xml:ext-link
    \begingroup
        \expandUx % commenting this out makes it work
                               \expanded{\goto{\hyphenatedurl{\xmlflush{#1}}}[url(\xmlflush{#1})]}
    \endgroup
\stopxmlsetups
%%%%%%%%%%%%%%%%%%%%

Best,
Denis
