Hello,
<xsl: if test="not(exists( (b/c) ) )" > ... </xsl:if>
Check other functions here:

You can use all xpath functions in the if/when test condition.

Subject: [xsl] Determining whether no single instance of a specific node
exists
Hi Everyone,
I have the following XML document:
<a>
<b/>
<b/>
<b/>
</a>
<a>
<b/>
<b/>
<b>
<c/>
</b>
</a>
<a>
<b/>
<b/>
<b/>
</a>
For each <b/> set, I want to apply a transformation only if no single
instance of <c/> exists. I know how to check whether a node does
exist, but not how to check whether no single instance of the node
exists.
I've tried the following conditional statements without success:
1,
<xsl:when test="not(a/b/c)">
2.
<xsl:when test="count(not(a/b/c)) >= 1">
What conditional statement should I use?
Thanks in advance for any help.
Mark
