Ok, then if I make the template more generic.. ie:
In my response I made it generic by declaring the type of the
parameter as an item:
<xsl:pram name="n" as="item()"/>
<xsl:function name="qp:test" as="item()*"
xmlns:functx="http://www.qplegaleze.ca";>
<xsl:param name="n"/>
Is there a way to test if $n is a String?
Sure:
<xsl:when test="$n instance of xsd:string">
... but because your second <xsl:when> relies on $n being a node, I
thought it safest to catch all atomic values by testing that the
argument isn't a node. I tell my students to write their
transformations defensively so as to catch unexpected inputs. I
don't think it is safe to simply check only for a string because the
next test is going to choke on atomic values of other types.
I hope this helps.
