Re: [xsl] Re: Determining whether no single instance of a specific node exists

[Mark Peters <markpeters.work@xxxxxxxxx>]

Hi Everyone,

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

This statement looks correct, but it isn't working for me. The
statement filters the sets of <b/> nodes where the first node does not
contain <c/>.  But if the first <b/> node in the set contains a <c/>,
then the set is not filtered. It looks like the count() function is
only looking at the first <b/> node.

I tried the following statement instead:

     <xsl:for-each select="attributeList/attribute">
          <xsl:variable name="counter" select="count(not[notChangeable])"/>
     </xsl:for-each>

     <xsl:choose>
          <xsl:when test="$counter &gt;= 1">
     ...

But the processor replied that $counter was not set.

I tried test="not(b/c)" earlier, with the same results as the first
statement in this email: The statement appears to filter on the first
<b/> node in the set only.

Thanks,
Mark
