You need the xx:node-set() extension. But there's a simpler solution: create it as a node-set in the first place, by writing: <xsl:variable name="record" select="document(fullKey)/xmldata"/> I see a great deal of this unnecessary creation of result tree fragments. Whenever you see <xsl:variable name="x"><xsl:value-of select="Y"/></xsl:variable> it should almost always be rewritten as <xsl:variable name="x" select="Y"/> Michael Kay Software AG home: Michael.H.Kay@xxxxxxxxxxxx work: Michael.Kay@xxxxxxxxxxxxxx > > This is very strange since I used the same way to access data > in another stylesheet and everything works just fine.
