coupling node name to xmlsetup

coupling node name to xmlsetup

[Hans van der Meer]

[-- Attachment #1.1: Type: text/plain, Size: 590 bytes --]

Suppose we have node <example> and want to execute the xmlsetup: mysetups:examplehandler on it. The idea is not to hardcode this but to do it on the fly from <definesetup name=“example”>.

The following \xmlsetup comes into mind:

\startxmlsetups mysetups:definesetup
	\xmlsetsetup{#1}{\xmlatt{#1}{name}}{mysetups:examplehandler}
\stopxmlsetups
\startxmlsetups mysetups:examplehandler
...
\stopxmlsetups

But this is either the wrong call or there is something missing, because on input of <example/> the examplehandler is not invoked.
How to?

Hi,

I’ll bump this, because the idea sounded intriguing to me as well.

I assume that should have been 

  \xmlsetsetup{\xmldocument}{\xmlatt{#1}{name}}{mysetups:examplehandler}

but with that, it does not work either. My MWE looks like this:

\enabletrackers[lxml.*]

\startxmlsetups mysetups:examplehandler
  examplehandler
\stopxmlsetups

\startxmlsetups mysetups:definesetup
  definesetup\par
  \xmlsetsetup{\xmldocument}{\xmlatt{#1}{name}}{mysetups:examplehandler}
\stopxmlsetups

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

\startxmlsetups mysetups:oursetups
  \xmlsetsetup{\xmldocument}{*}{+}
  \xmlsetsetup{\xmldocument}{xml|definesetup}{mysetups:*}
\stopxmlsetups

\xmlregistersetup{mysetups:oursetups}

\starttext
\startbuffer[xml]
<xml>
<definesetup name="example">
   whatever
</definesetup>
<example>
   inputted text
</example>
</xml>
\stopbuffer

\xmlprocessbuffer{main}{xml}{}

\stoptext
