Regular Expression

Hello All,

Is it possible to give a regular expression in match string ?
For example:
<?xml version="1.0" encoding="UTF-8"?>
<Task>
	<Parameter Name = "DispTag">
		<Help>DispTag Parameter help</Help>
	</Parameter>
	<Parameter Name = "CreateTag">
		<Help>CreateTag Parameter help</Help>
	</Parameter>
	<Parameter Name = "DispElement">
		<Help>DispElement Parameter help</Help>
	</Parameter>
	<Parameter Name = "CreateElement">
		<Help>CreateElement Parameter help</Help>
	</Parameter>
</Task>
Is it possible to find list of parameters, name starts with "Disp" or "Create"
?

Some thing like
<xsl:applytemplate match="Disp[a-z]*">

Thanks and Regards,
Chandu
