Coldfusion and XML - need assistance reading XML values - am desperate!

I'm afraid I have virtually no experience working with XML & Coldfusion, so any advice that anyone can provide would be great.  I am trying to grab a web page and get the certain values into a database.  The web page I am calling with <cfhttp> is a php file that returns contents as XML.

i.e.
<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE workspace PUBLIC "-//workname//DTD workspace 1.0" "http://localhost:8080/workspace/p.dtd">
<working type="d">
          <off><u>132915</u></off>
</working>
<working type="d">
    <on><u>132915</u></on>
</working >
<working type="d">
          <off><u>13112</u></off>
</working>

I am totally baffled as to how to accomplish getting the values for which numbers come across as <off></off> and which come across as <on></on> read out of the xml and into a usuable format.  If you need more information or I am not clear on this, please just let me know!

Thanks!

Hi there, maybe it's easier to post the php page, it's very important that the page is formatted correctly and wrapped up correctly with tags (like: <item><grabthis></grabthis></item> and maybe exported to .xml format, then you should request the page like:

<!--- Retrieve the RSS document --->
<cfhttp url="http://wwwphppage.php" method="get">

<!--- Validation flag --->
<cfset XMLVALIDATION = true>

<cftry>
<!--- Create the XML object --->
<cfset objRSS = xmlParse(cfhttp.filecontent)>

<cfcatch type="any">
<!--- If the document retrieved in the CFHTTP
is not valid set the validation flag to false. --->
<cfset XMLVALIDATION = false>
</cfcatch>
</cftry>

<cfif XMLVALIDATION>
<!--- If the validation flag is true continue parsing --->

<!--- Set the XML Root --->
<cfset XMLRoot = objRSS.XmlRoot>

<!--- Retrieve the document META data --->
<cfset doc_grabthis = XMLRoot.channel.grabthis.xmltext>

<!--- Output the meta data in the browser --->

<!--- Retrieve the number of items in the channel --->
<cfset Item_Length = arraylen(XMLRoot.channel.item)>

<!--- Loop through all the items --->
<cfloop index="itms" from="1" to="#Item_Length#">
<!--- Retrieve the current Item in the loop --->
<cfset tmp_Item = XMLRoot.channel.item[itms]>

<!--- Retrieve the item data --->
<cfset grabthis = tmp_Item.grabthis.xmltext>

<!--- Output the items in the browser --->
<cfoutput>
#grabthis#
</cfoutput>
 . </cfloop>
<cfelse>
<!--- If the validation flag is false display error --->
Invalid XML/RSS object!
</cfif>

I'm not really a php guy, but if you need more advice and maybe post the code i will give it a try :)

Thanks for your help Marco!  In the end I decided to write a parser to grab the data I needed - I  figured that I am not dealing with a huge amount of data anyway, so it just made more sense.  Here is the parser in case anyone else runs into this and wants to see an alternative:

<cfscript>
      onList = "";
      if (findNoCase("<on>", xmlString))
      {
            onList = removeChars(xmlString, 1, findNoCase("<on>", xmlString) + 6);
            onList = replaceNoCase(removeChars(onList, findNoCase("</on>", onList) - 4, len(onList)), "</u><u>", ",", "all");
      }
      
      offList = "";
      if (findNoCase("<off>", xmlString))
      {
            offList = removeChars(xmlString, 1, findNoCase("<off>", xmlString) + 7);
            offList = replaceNoCase(removeChars(offList, findNoCase("</off>", offList) - 5, len(offList)), "</u><u>", ",", "all");
      }
</cfscript>
