Re: [xsl] Finding if a node exists

[Joerg Heinicke <joerg dot heinicke at gmx dot de>]

The easiest way is to apply a template on this node. If it exists, it 
works, if not, then not:

XML:

<xml>
   <test>test</test>
</xml>

XSL:

<xsl:template match="xml">
   <xsl:apply-templates select="test"/>
   <xsl:apply-templates select="test2"/>
</xsl:template>

<xsl:template match="test">
   <xsl:value-of select="."/>
</xsl:template>

<xsl:template match="test2">
   <xsl:text>test2-node exists</xsl:text>
</xsl:template>

Now 'test2-node exists' won't appear. If you add <test2/> to the 
XML-source, it will appear.

Joerg
