This is a faq, you can't in standard xsl evaluate a string as an xpath
expresion. Check the archives of this list.

> "Reference to a variable or parameter "selectpath" must evaluate to a node 
> list."

you have <xsl:value-of select="$selectpath"/>

but you passed it a string: "Resources/Resource"

so it is equivalent to

<xsl:value-of select="'Resources/Resource'"/>
