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

       %~ \xmlsetsetup{#1}{h2/**/ul/li}{xml:last:item} % nothing changes
       \xmlsetsetup{#1}{h2/***/ul/li/!ul}{xml:last:item} % shouldn’t be
this one?

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?
This should work but we're one off so i need to fix that.
\startbuffer[demo]
<document>
   <ul>
     <li>first</li>
     <li>any</li>
     <li>last</li>
   </ul>
</document>
\stopbuffer

\startxmlsetups xml:demo:base
   \xmlsetsetup{#1}{document|ul|li}{xml:*}
   \xmlsetsetup{#1}{ul/li[1]}{xml:item:first}
   \xmlsetsetup{#1}{ul/li[-1]}{xml:item:last}
\stopxmlsetups

\xmlregistersetup{xml:demo:base}

\startxmlsetups xml:document
   \xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:ul
  \startitemize
    \xmlflush{#1}
  \stopitemize
\stopxmlsetups

\startxmlsetups xml:li
   \startitem
     \xmlflush{#1}
   \stopitem
\stopxmlsetups

\startxmlsetups xml:item:first
   \startitem
     \color[blue]{\xmlflush{#1}}
   \stopitem
\stopxmlsetups

\startxmlsetups xml:item:last
   \startitem
     \color[red]{\xmlflush{#1}}
