Re: [xsl] Finding if a node exists

["cutlass" <cutlass at secure0 dot com>]

a processor intensive method would be


<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
 <xsl:template match="/">

 <xsl:variable name="test" select="boolean(//a)"/>

 </xsl:template>
</xsl:stylesheet>


where the node u are looking for is a, if a is present it would be true

the result is placed in a variable named test.

though this may be optimised if u tell us a little bit more of the situation
u want to achieve.

cheers, jim fuller
