[xsl] Re: When is a variable a nodeset and when isn't it?

["Dimitre Novatchev" <dnovatchev@xxxxxxxxx>]

String and node-set are different datatypes in XPath -- a string cannot be
used where a node-set is expected.

Therefore:

      /x/y/'someString'/z

is illegal.

So is:

    /x/y/$someVariable/z

Try using:

   /x/y/*[name() = $someVariableContainingAString]/z
