Hi
Can anyone tell me what is wrong with the following stylesheet?
In the "analyse_node" (I speak English, not American) template
I'm trying to determine the type of the current node and print
out an appropriate message. Currently only the element test
self::* works. I would have thought that self::text() would
return true if the current node was text - but it keeps passing
straight through to the <xsl:otherwise> branch.
Thanks in advance.
