Thanks again to everyone for the help!

This gives me a variable that tells me how many cautions are preceding

In XPath 2.0,
count(preceding::caution intersect ancestor::chapter//caution)
In 1.0, you can simulate the intersect operator using the equivalence
A intersect B ==> A[count(.|B) = count(B)]
But you might be better off using
<xsl:number count="caution" level="any" from="chapter"/>

Subject: [xsl] Xpath to count occurances within a single parent
Hello all,
I have the following XML structure
<book>
<chapter>
<caution/>
<caution/>
<caution/>
</chapter>
<chapter>
<sect1>
<caution/>
</sect1>
<caution/>
<caution/>
</chapter>
</book>
What I need is an XPATH statement that counts the number of preceding
cautions in each chapter. From any given chapter element.
EXAMPLE:
count(preceding::caution)!= 0
This XPATH works correctly for the first <chapter> but fails on the
second <chapter> because one <caution> is a child of <sect1>.
Is there a way to count preceding <cautions> within a <chapter>
element despite nesting?
Thanks,
David White
