Hey Shawn,
It's just 9am here so my apologies for a short answer (or rather, the
short hint) - try looking into XPath. Either do a search on Google or
take a look at the XPath spec http://www.w3.org/TR/xpath
A demo of the XML you're using would've been useful, but from what
you've said I'm assuming it's something like this:
<rootelement>
<blah>
</blah>
<event>
<someelement/>
</event>
<event>
<headerlinks>
<name>fred</name>
<url>http://www.somewhere.com</url>
</headerlinks>
</event>
</rootelement>
From what I can see, get the XML into a variable then construct your
XPath var, perhaps something like
<cfset xpathvar = "/descendant::event/child:headerlinks"/>
Then this:
<cfset headerlinks = XMLSearch(varWithXMLInIt, xpathvar)/>
That should throw all of the elements that match your XPath expression
into headerlinks, which will be an array.
Best to read through some articles on XPath 'cos I'm sure that the above
expression won't do exactly what you're after. The W3C spec is, as
usual, hefty and complicated (especially at 9am!) hence the reason why I
think my expression won't work properly but it should give you a pointer
on where to start looking.
Hope that helps somewhat,
