Subject: Re: [xsl] test if null From: David Carlisle <davidc@xxxxxxxxx> Date: Mon, 27 Jun 2005 10:39:02 +0100 |
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())]"> David ________________________________________________________________________ This e-mail has been scanned for all viruses by Star.
