XPath for variable search anywhere

Dear all,

I have a variable in my XSL (call it myVar) and I wish to search the entire 
node hierarchy for nodes which share it's name.  You could say I want to 
combine the syntax
<xsl:copy-of select="//aNodeName">

with

<xsl:copy-of select="$myVar">

but the syntax I want

<xsl:copy-of select="//$myVar">

causes my processor (4suite) to generate an XsltException.  Does anybody 
know the syntax I need to look at all levels of the hierarchy for nodes that 
have the name (or attribute) "myVar"?
Thanks a lot,

Mr Andrew Maclean
