Hi all,
I'm resurrecting an ooooold thread and top-posting... For details, see
the post below. The problem was that the content of itemizations
sometimes disappeared in xml processed by mkiv. I emphasize
"sometimes": now you see it, now you don't... I can't really post a
minimal example that will be certain to display the effect, but I
have, since May, discovered one thing:
this code:
<item>
  A
</item>
will sometimes make the A disappear. This code:
<item>A</item>
will always work correctly. So Hans, a shot in the dark: can it be
that your lpeg xml parser can, under certain circumstances, have
trouble with linebreaks within the xml-subtree it is trying to pick
up? That would explain the mystery which had me baffled back in May.
All best
Thomas
Can you test the following definition for item a while:

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

Wolfgang

Hi all,
I played some more with the new mkiv xml mechanism and am beginning
to
see the light: some things that turned out to be very difficult (at
least for me) with the "old" mechanism are easy now. However, I  
still
have a couple of questions:
1. I have this minimal file test.xml:
<document>
<itemize>
  <item>
    one
  </item>
  <item>
    two
  </item>
  <item>
    three
  </item>
</itemize>
</document>
and this minimal environment test-style.tex:
\startxmlsetups xml:mysetups
     \xmlsetsetup{\xmldocument}{document|itemize|item}{xml:*}
\stopxmlsetups
\xmlregistersetup{xml:mysetups}
\startxmlsetups xml:document
     \xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:itemize
     \startitemize
     \xmlflush{#1}
     \stopitemize
\stopxmlsetups
\startxmlsetups xml:item
     \item \xmlflush{#1}
\stopxmlsetups
\starttext
\xmlprocess{main}{\inputfilename}{}
\stoptext
When I run texexec --lua --env=test-style test.xml, I get output  
only
for item "three," not for one and two. What am I doing wrong?
2. In every run, I get this warning:
TeXUtil | check loading of file 'test-style', begin/end problem
I don't see anything wrong with my files, though. Is this harmless?
3. I have a structure like this to get numbered labels:
<lemmasection>
    <label>1234</label>
    <content>
     blahblah
    </content>
  </lemmasection>
you could try something like
\startxmlsetups xml:lemma
\startlemma{\xmlfirst{#1}{label}}
\ignorespaces\xmlfirst{#1}{content}\removeunwatedspaces
\stoplemma
\stopxmlsetups
