Hi Micheal,

Your statement looks right. I'll play around with it.

Thanks for your help.

Sorry, my XSL examples weren't quite right.  I'm trying to determine
whether no instance of <c/> exists for each <b/> set.

So, in my XSL document, assume I'm processing each <a/> node.

1,
<xsl:when test="not(b/c)">

2.
<xsl:when test="count(not(b/c)) &gt;= 1">

Thanks,
Mark

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)) &gt;= 1">


What conditional statement should I use?

Thanks in advance for any help.


Are you looking for something along the line of

<xsl:when test="not(count(b/c) &gt;= 1)">
??
