XPath help?

[Muddmuse]

Here is some sample XML:

<?xml version=&quot;1.0&quot;?>
<Data>
<LineItems>
<LineItem>
<A>1</A>
<B>2</B>
</LineItem>
<LineItem>
<A>3</A>
<B>4</B>
<C>5</C>
<Z>X</Z>
</LineItem>
</LineItems>
</Data>

I'm have a template to match &quot;LineItems&quot; and in it am doing a for-each loop on &quot;LineItem&quot;. My problem is this. If a LineItem node has a child of Z I need to know the count of that LineItem child nodes, excluding Z (In the above example the answer would be 3).

Can anyone assist me in creating this expression? Thanks in advance.

sure i'll give it a shot

in xpath you have the ability to search for child nodes using the &quot;child::&quot; expression. for example to test if a node has the child node Z you would do:

<xsl:if test=&quot;child::Z&quot;>
</xsl:if>

...

as a brief and very unsophisticated answer to your problem i have written this:

<?xml version=&quot;1.0&quot;?>
<xsl:stylesheet version=&quot;1.0&quot; xmlns:xsl=&quot;

http://www.w3.org/1999/XSL/Transform&quot;>

<xsl:template match=&quot;Data&quot;>
<xsl:for-each select=&quot;//LineItem&quot;>
<xsl:if test=&quot;child::Z&quot;>
<!-- do something here -->
<xsl:value-of select=&quot;count(*) - count(child::Z)&quot;/>
</xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

... I hope you can see what I am trying to do.

Hope this helps
