I got tired of waiting for Macromedia to fix the bug in XMLSearch, so I wrote this User Defined Function that will bypass the problem with xpath searching when the xmlns attribute is set in the XMLDoc.
The code below uses a regular expression to strip the xmlns attribute out of the XMLDoc before performing the xpath search.
<cffunction name="fixedXMLSearchOld" access="public" returntype="array">
<cfargument name="XMLString" type="Any" />
<cfargument name="xPathString" type="string"
<cfset var myRegEx = 'xmlns[ ]*=[ ]*"[[:graph:]]+"' />
<cfset var currentXMLString = "" />
<cfset var currentXMLDoc = xmlNew() />
<cfset var myArray = arrayNew(1) />
<cfif isXMLDoc(arguments.XMLString)>
<cfset currentXMLString = rereplaceNoCase(toString(arguments.XMLString),myRegEx,"","all") />
<cfelse>
<cfset currentXMLString = rereplaceNoCase(arguments.XMLString,myRegEx,"","all") />
</cfif>
<cfset currentXMLDoc = XMLParse(currentXMLString) />
<cfset myArray = XMLSearch(currentXMLDoc,xPathString) />
<cfreturn myArray />
</cffunction>I also wrote a version in cfscript.
function fixedXMLSearch(XMLString, xPathString) {
var myRegEx = 'xmlns[ ]*=[ ]*<font color="BLUE">"[[:graph:]]+"</font>';
var currentXMLString = <font color="BLUE">""</font>;
var currentXMLDoc = xmlNew();
var myArray = arrayNew(<font color="BLUE">1</font>);
if (isXMLDoc(arguments.XMLString)) {
currentXMLString = rereplaceNoCase(toString(arguments.XMLString),myRegEx,<font color="BLUE">""</font>,<font color="BLUE">"all"</font>);
} else {
currentXMLString = rereplaceNoCase(arguments.XMLString,myRegEx,<font color="BLUE">""</font>,<font color="BLUE">"all"</font>);
}
currentXMLDoc = XMLParse(currentXMLString);
myArray = XMLSearch(currentXMLDoc,xPathString);
return myArray;
}
