Then by "template selection pattern" I assume you want
<xsl:apply-templates> and not <xsl:template> as was implied by your example.

Not "convert" but there is a way to *use* your string variable in a node
set expression, which is what is used to select the nodes for processing.

The only place to use the string variable is in a predicate, so in order to
get the children of the current node named by the variable $mystring, you
would use:

XSL-19990421:

   <xsl:apply-templates select="*[qname(.)=$mystring]"/>

XSL-19990709:

   <xsl:apply-templates select="*[name(.)=$mystring]"/>

In this way you are selecting all your children (using "*") and then
filtering them with the predicate "name(.)=$mystring" to get only those
children named by your string variable.

I hope this helps.
