Counting nodes 1

[mcowen]

I want to count the number of cases in my xsl page (CASE being the parent element). I see that there is a XPath function called count() but I dont know how to use it nor whether it does what I want.

Thanks

You call count() with an XPath query and it returns the number of hits. It's fairly slow, so don't overuse it.

<xsl:if test=&quot;count(/rootnode/a/b/c) > 0&quot;>
   <!-- do something -->
</xsl:if>

Cheers for this. This looks correct but XMLSpy says this is not well formed and it expects an & before the less than symbol.

<xsl:if test=&quot;count(VFILE_DATA/SUMMARY) < 2&quot;/>;

</xsl:if>

Ok sorted it. When using this in a XSL page you need to convert the < char to &quot;&lt;&quot;.
