Here's the XML validation function for ColdFusion MX that I promised
yesterday. It requires JDOM (http://www.jdom.org/) which MX uses internally,
so it should run on all MX installations.
Hope this helps - let me know if you have any problems.

<!--- XML validation function --->
<cffunction name = "XMLValidate" returntype="boolean">
<cfargument name="XMLSource" required="true">
<cfobject
class = "org.jdom.input.SAXBuilder"
name = "SAXBuilder"
action="create"
type = "java">
<cfset setVal = SAXBuilder.setValidation(true)>
<cfset XMLValidateError = "">
<cfset XMLValid = 1>
<cftry>
<cfset trybuild = SAXBuilder.build(XMLSource)>
<cfcatch>
<cfset XMLValidateError = cfcatch.message>
<cfset XMLValid = 0>
</cfcatch>
</cftry>
<cfreturn XMLValid>
</cffunction>
<!--- example usage --->
<cfset checkDoc = XMLValidate('http://torchbox.com/xml/test.xml')>
<cfif CheckDoc>
The XML document is valid
<cfelse>
There is an error in the XML document: <br />
<cfoutput>#XMLValidateError#</cfoutput>
</cfif>
