As I said, sometimes I just can't see the easy way to solve a doubt :) Thank you very much, Frank -----Original Message----- From: David Carlisle [mailto:davidc@xxxxxxxxx] Sent: lunes, 17 de septiembre de 2001 11:36 To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: Re: [xsl] Non-existing node > if there's any reserved word or something to refer to an empty-nodeset. > Let's say the reserved word is "ENS" (Empty Node Set), that way you could > write something like this: > > <xsl:if test="Parent/MyNode=ENS">...</xsl:if> There are no reserved words in XPath at all (which is an important feature as it has to work with any XML: ENS in the above selects child elements called ENS, there are no words "free". In this case you dion't want an = test at all, a non empty node set coerces to true, so you just need <xsl:if test="not(Parent/MyNode)">...</xsl:if> David _____________________________________________________________________ This message has been checked for all known viruses by Star Internet delivered through the MessageLabs Virus Scanning Service.
