This line of code comes from the xml documentation (page 31):
\xmlfilter{#1}{./node[@type=="cleanup"]}
It should select among the <node>'s those with <node type="cleanup">.
However, this node is not selected in the call to \xmlfilter.
Where am I wrong?

MWE follows


% failure to typeset attribute selected.
\setuppapersize[A5][A5]
\startxmlsetups demo:attribute
	\xmlsetsetup{#1}{root|node}{demo:attribute:*}
\stopxmlsetups
\xmlregisterdocumentsetup{demo}{demo:attribute}
\startxmlsetups demo:attribute:root
	Execute \type{\xmlall{#1}{./node}}
		\crlf
		\xmlall{#1}{./node}
		\crlf
	Execute \type{\xmlfilter{#1}{./node[@type=="cleanup"]}}
		\xmlfilter{#1}{./node[@type=="cleanup"]}
		\crlf
\stopxmlsetups
\startxmlsetups demo:attribute:node
	calling node <\xmltag{#1}>
	\xmlflush{#1}
	\crlf
\stopxmlsetups
\startbuffer[attribute]
<root>
<node>no attribute</node>
<node type="cleanup">attribute type = cleanup</node>
</root>
\stopbuffer
\startbuffer[attribute2]
<root>
<node>no attribute</node>
<node type="cleanup">attribute type=cleanup</node>
</root>
\stopbuffer
\starttext
\ConTeXt\ version\contextversion\blank
\xmlprocessbuffer{demo}{attribute}{}
\stoptext

Finally I saw the problem. Calling \xmlfilter{#1}{./node/command(demo:attribute:node)} is the right way.
Sorry for the noise.
