Hi,
sorry for the messed up message I sent from my other mail account. I
should have known that it wouldn't work as I experienced this issue
before.
Is there a way to determine whether a variable holds a string or a
node set? Something like:
no in xslt 1 all you can do is a static analysis of all teh places where
your template is called and see if it is called with the smae type always.
<xsl:template name="my-template">
<xsl:param name="arg"/>
Note that makes the default value an epty string which is dangerous if
the value passed in is going to be a node set and you want to do
$arg/some/path. Safer is to declare it as
<xsl:param name="arg" select="/.."/>
so the default value is a (empty) node set and then it is safe to do
$arg/some/path
without having to test the type, so long as you always pass in a node set.
