desperate for xmlstrip

I really need to remove the leading and trailing whitespace from nodes.
Tried in vain to get \xmlstrip (and friends like \xmlstripnolines)  
working.
Just doing \xmlstripped{node}{lpath} is not adequate, because I want  
to order the output when a node contains several subnodes (using  
\xmlfilter for this).
Below a minimal example. Tweaking the \xmlstrip in all sorts of way  
did not help.

\startxmlsetups xml:testsetups
	\xmlsetsetup{test}{test|a|b|c}{xml:*}
\stopxmlsetups
\xmlregistersetup{xml:testsetups}

\startxmlsetups xml:test
	\xmlstrip{#1}{}
	\xmltext{#1}{} No spaces should showup between nodes!
\stopxmlsetups

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

\startxmlsetups xml:b
	\xmltext{#1}{}
\stopxmlsetups

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

\starttext
\xmlprocessfile{test}{test.xml}{}
\stoptext

Input xml-file:
<?xml version="1.0" encoding="UTF-8"?>
<test>
	<a>
		This is node a:
		<b>
			:Node b:
		</b>
		<c>
			:Node c:
		</c>
	</a>
</test>

The result:
