combinations ins XML

combinations ins XML

[varheit]

Dear all,

I would like to use the combination feature from an XML source.

My XML environment file includes the following definitions:

\defineXMLenvironment[combination]
 
{\expanded{\startcombination[\XMLpar{combination}{layout}{2}*\XMLpar{combination}{rows}{1}]}}
  {\stopcombination}

\defineXMLpickup[combinationentry]
  {\defineXMLpush[combinationitem]\defineXMLpush[combinationcaption]}
 
{\expanded{\bgroup\XMLpop{combinationitem}\egroup\bgroup\XMLpop{combinationcaption}\egroup}}


The XML source that I use looks like this:

    <combination columns="2" rows="1">
      <combinationentry>
	<combinationitem>Image A</combinationitem>
	<combinationcaption>Caption for image A</combinationcaption>
      </combinationentry>
      <combinationentry>
	<combinationitem>Image B</combinationitem>
	<combinationcaption>Caption for image B</combinationcaption>
      </combinationentry>
    </combination>


When I process this file I always get the following error:

! Missing { inserted.
<to be read again>
                   \def
\parseXMLelement #1#2 #3>->\def
                                \currentXMLarguments {#3}\if #1/\chardef
\ki...
l.5       <combinationentry>

?

I have tried different variations without any success.
Maybe somebody can help me.

Vik

ah, real trickery is needed here:

\defineXMLenvironment [combination] [columns=2,rows=1]
   {\scratchtoks\emptytoks
    \expanded{\appendtoks \noexpand \startcombination
      [\XMLop{columns}*\XMLop{rows}]}\to \scratchtoks}
   {\appendtoks \stopcombination \to \scratchtoks
    \the\scratchtoks}

\defineXMLprocess[combinationentry]

\defineXMLpickup [combinationitem]
   {\appendtoks\bgroup}{\egroup\to\scratchtoks}

\defineXMLpickup [combinationcaption]
   {\appendtoks\bgroup}{\egroup\to\scratchtoks}

I can add such thing to x-contml.tex if needed
