Your intuition was correct, you can indeed use
"/entry[index]/category" - except that index would want to be a
numerical value; ie.
<cfset variables.xml =
XmlParse('http://www.blogger.com/feeds/1550840680584738668/posts/default?published-min=2008-11-11T00:00:00&published-max=2008-11-25T23:59:59')>
<cfset variables.entries = XmlSearch(xml, '/:feed/:entry')>
<cfoutput>
<cfloop from="1" to="#ArrayLen(entries)#" index="variables.i">
<cfset variables.categories = XmlSearch(xml,
'/:feed/:entry[#i#]/:category')>
<!--- ... etc. --->
</cfloop>
</cfoutput>
A quick example of what else can be done using XPath in this way:
//[EMAIL PROTECTED]"http://www.google.com"]/category
This will select all the category elements with in an entry element
that has an 'id' attribute with a value of 'http://www.google.com'.
XML and XPath are wonderful beasts. While it may not help you in terms
of your deadline; I'd highly recommend getting a copy of "XML In A
Nutshell". XML can be tricky to explain and this book does it really
comprehensively and readably. W3Schools also have a fairly good
reference and forum:
