RE: [xsl] Nodeset problem

["Michael Kay" <mike@xxxxxxxxxxxx>]

I suspect the code you posted isn't the code you executed (variables $nodes
is undeclared - perhaps $foonodes intended???) - which means that it's
difficult to distinguish your real error from any typos introduced in the
transcription process.

But I'm suspicious of contains($foolist,$foo) - I suspect you're falling
into the trap of imagining that contains() tests whether a set of values
contains a value. It actually tests whether a string contains a substring.
You probably just want ($foolist = $foo). But the whole lookup would be
better done using keys.
