Hi,
I'm parsing some RSS feeds and I'm not able to check if some elements are defined or not.
In example, I receive this error:
Element CATEGORY.XMLTEXT is undefined in a Java object of type class coldfusion.xml.XmlNodeMap referenced as
when a category of the ITEM is not defined.
I tried to check if
isDefined(XMLContent.rss.channel.item[idx].category.xmlText)
or
ParameterExists(XMLContent.rss.channel.item[idx].category.xmlText)
without success.
What is the right method to check it?

EXISTS
<cfelse>
DOES NOT EXISTS
</cfif>
