[NTG-context] Re: XML processing beginner's question

["Michael Löscher" <mloescher27@outlook.de>]

Yes, I have done that. But I don't seem to have the basic context of how 
the processing works in order. All I have so far is this as a starting 
point:

\startxmlsetups xml:mysetup
 
\xmlsetsetup{main}{document|element|mdata|tdata|name|date|num|content|shortdescription|p}{xml:*}
\stopxmlsetups

\xmlregistersetup{xml:mysetup}

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

\startxmlsetups xml:mysetup:element
\xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:mysetup:mdata
\xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:mysetup:tdata
\xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:mysetup:name
\xmlflush
\stopxmlsetups

\startxmlsetups xml:mysetup:num
\xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:mysetup:content
\xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:mysetup:shortdescription
\xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:mysetup:p
\xmlflush{#1}\par
\stopxmlsetups

\starttext
   \xmlprocessbuffer {mysetup}{xmlcontent}{}
\stoptext
