Parsing XML

[sdsinc_pmascari]

I've used CFMX7 to parse several XML documents, but I'm having trouble with the XML syntax of my latest assignment when there is a colon ( : ) in the XML tag. Help is appreciated:

XML Sample Snippet:

<rdf:RDF xmlns=" http://purl.org/rss/1.0/">
<channel rdf:about=" http://somewebsite/somedirectory/">
</channel>
<item rdf:about=" http://somewebsite/somedirectory/somestory.html">
</item>
</rdf:RDF>

My code:

<cfset ParsedRSSData = XMLParse(XmlObj)>

#ArrayLen(XMLSearch(ParsedRSSData,"rdf:RDF/"))# ----> results in 1.

However, #ArrayLen(XMLSearch(ParsedRSSData,"rdf:RDF/channel/"))# ----> Results in 0. Why?

Also trying to display data, #ParsedRSSData.rdf:RDF.XmlAttributes.xmlns# ----> Results in a CF error:

Invalid CFML construct

ColdFusion was looking at the following text:

:

How do I structure the CF code to handle the colons ( : ) in the XML?

Thanks!

This is how I handled this issue. I used XSLT and xmlTransform()
functions instead of the xmlSearch() function. HTH.

<cfhttp url=" http://www.houseoffusion.com/groups/Flex/RSS.cfm"
method="get" />
<cfset HOF = XMLParse(cfhttp.filecontent)>

<cfhttp
url=" http://weblogs.macromedia.com/product_feeds/archives/flex/index.rdf"
method="get" />
<cfset Adobe = XMLParse(cfhttp.filecontent)>

<cffile action="read" file="G:\playground\rss_feeds\rss_1.xsl"
variable="RSS_1">

<cffile action="read" file="G:\playground\rss_feeds\rss_2.xsl"
variable="RSS_2">

<cfoutput>#xmlTransform(HOF,RSS_2)#</cfoutput>
<hr />
<cfoutput>#xmlTransform(Adobe,RSS_1)#</cfoutput>

And the XSLT files:
