Dear list,
I have the following sample:
\startbuffer[demo]
<document>
<h2 id="heading">Heading</h2>
<ul>
<li>list</li>
</ul>
<h2 id="heading-1">Heading</h2>
<ul>
<li>list
<ul>
<li>list</li>
</ul></li>
</ul>
<h2 id="heading-2">Heading</h2>
<ul>
<li>list
<ul>
<li>list
<ul>
<li>list</li>
</ul></li>
</ul></li>
</ul>
</document>
\stopbuffer
\startxmlsetups xml:demo:base
\xmlsetsetup{#1}{document|h2|ul|li}{xml:*}
%~ \xmlsetsetup{#1}{ul/li/!ul}{xml:last:item} % nothing changes
%~ \xmlsetsetup{#1}{ul/li/!li}{xml:last:item} % blank item inserted
%~ \xmlsetsetup{#1}{h2/**/ul/li}{xml:last:item} % nothing changes
\xmlsetsetup{#1}{h2/***/ul/li/!ul}{xml:last:item} % shouldn’t be
this one?
\stopxmlsetups
\xmlregistersetup{xml:demo:base}
\startxmlsetups xml:document
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:h2
\section{\xmlflush{#1}}
\stopxmlsetups
\startxmlsetups xml:ul
\startitemize\xmlflush{#1}\stopitemize
\stopxmlsetups
\startxmlsetups xml:li
\startitem\xmlflush{#1}\stopitem
\stopxmlsetups
\startxmlsetups xml:last:item
\startitem\red\xmlflush{#1}\stopitem
\stopxmlsetups
\starttext
\xmlprocessbuffer{main}{demo}{}
\stoptext
I need to be able to select the last <li> (the one with no <ul> child)
in the <h2> element.
I thought that the lpath for that would be "h2/***/ul/li/!ul", but I
don’t know what I’m missing, since it doesn’t work at all.
Which would be the right lpath to select the last item in each list?
Many thanks for your help,
Pablo

This should work but we're one off so i need to fix that.

Many thanks for your help, Hans.
This is like magic to me. But I’m afraid that my description was inaccurate.
I need to mark the last item from nested lists, but considering each
<h2> (such as in my sample), not the whole document.
Just in case it isn’t clear, this is the XML source with desired items
marked:
<document>
<h2 id="heading">Heading</h2>
<ul>
<li>list</li> ***this one***
</ul>
<h2 id="heading-1">Heading</h2>
<ul>
<li>list
<ul>
<li>list</li> ***this one***
</ul></li>
</ul>
<h2 id="heading-2">Heading</h2>
<ul>
<li>list
<ul>
<li>list
<ul>
<li>list</li> ***this one***
</ul></li>
</ul></li>
</ul>
</document>
I hope it is clear now that it is the last item in a nested list, but
for each <h2> element.
Many thanks for your help again,
Pablo
