How would i test if a node is null?
XPath doesn't have a null value. Testing for empty has an entry in teh
FAQ.
like i have this empty node <EMPTYNODE />
<xsl:when test="EMPTYNODE[.!= '']">
is not working.
That tests if the string value of EMPTYNODE is not the empty string so
<EMPTYNODE /> and <EMPTYNODE ><foo/></EMPTYNODE> would test teh same way
as they both have a string value of ''.
If you want to test if teher eare no children, then the set of child
nodes will be empty
<xsl:when test="EMPTYNODE[not(node())]">
