Hi again,

now that everybody should be back from DANTE2010, I'll try that one
again:

[ ... ] snip

My latest try was \xmlinclude but that didn't work either.  When I have
the following setups

\startxmlsetups xml:afile
    \section{Filename \xmlatt{#1}{file}}
    %\xmlinclude{test} {  }          {\xmlatt{#1}{file}}
    %\xmlinclude{test} {/*}          {\xmlatt{#1}{file}}
    %\xmlinclude{test} {/sect}       {\xmlatt{#1}{file}}
    %\xmlinclude{test} {/sect/title} {\xmlatt{#1}{file}}
    \xmlinclude{test} {sect}        {\xmlatt{#1}{file}} 
\stopxmlsetups

Where “test” is the name of the document to be processed and "sect” is
the outermost node from the included file.

This produces nothing, but try uncommenting some lines: context fails
with a lua error.  Why this?  xml-mkiv says that the second argument to
\xmlinclude should be an lpath from “file” and <sect> is the first node
in the file (I'll attach it).

Is there anybody who could provide a working example of \xmlinclude or
reveal The Right Way of Including XML to me?

Thanks for any help,

Philipp
