Subject: Re: [xsl] exists function in xslt From: David Carlisle <davidc@xxxxxxxxx> Date: Fri, 30 Sep 2005 13:53:36 +0100 |
> why cant i use: exists() is an XPath 2 function, and xalan implements Xpath 1. You don't need it though. > <xsl:if test="exists(/XPATH-QUERY)) = true"> That tests if the string value of the element <true/> is equal to "true" which you probably don't want. The XPSLT test would be <xsl:if test="exists(/XPATH-QUERY)"> which you can equivalently write as <xsl:if test="/XPATH-QUERY"> Which would work also in an XSLT1 processor such as xalan.
