Could you show me what that if ($buyer) then fn:borrowerfullname($buyer) else () would look like in the function? Is this the 'right' way? <xsl:choose> <xsl:when test="$buyer"> ... </xsl:when> </xsl:choose> How do you return an empty string or empty element() set?

It's a stateless language. Concepually, everything happens at once. Accordingly, there's no concept of writing to a variable "at the start" and reading it "later". Your two <xsl:variable name="buyerfullname"/> instructions are declaring completely unrelated variables, the only thing they have in common is that they both have the same name. Just do the initialisation within the declaration of the global variable: <xsl:variable name="buyer" > select="Contract/Borrowers/Borrower[NumOrder='1']"/> <xsl:variable name="buyerfullname" select="fn:borrowerfullname($buyer)"/> You could make that <xsl:variable name="buyerfullname" select="if ($buyer) then fn:borrowerfullname($buyer) else ()"/> but I would personally put the logic for that inside the function.
