RE: [xsl] dynamic template naming XSL1.0 and Saxon 6.5.5

["Michael Kay" <mike@xxxxxxxxxxxx>]

Saxon in fact has an extension element

saxon:call-template 

which is like xsl:call-template except that the "name" attribute is an AVT.
You don't need saxon:evaluate with this, just write

<saxon:call-template name="{$testVar/Configuration/Execute/@template}"/>

It's always better, of course, to work without extensions if you can. You
might like to look at Dimitre Novatchev's FXSL technique, which exploits the
ability of xsl:apply-templates to do dynamic dispatch. Rather than having a
variable holding the name of a template to be invoked, you have a variable
holding a node, typically a node with a unique name in some special
namespace; and then you do apply-templates on that node. By putting
different nodes in the variable, you can then cause different templates to
be invoked.
