Cannot xmlSearch in CF2016

Again, while I leave it to Pete to discuss with you the alternatives for what you're trying, I want to focus solely on the original issue, where you felt that something working in 9 does not work in 2016.

So you confirm that the dump of the cfhttp.filecontent (that you're passing to xmlparse) is identical. Ok, we'll have to take your word for that. :-)

The next question would be whether you dumped the result of that parse, in your case xmlParseIn? Did you view that in CF2016? How does it look? And did you compare it to what you'd see in CF9?

Finally, just as another way to demonstrate that what you have shared SHOULD (and DOES) work in CF2016, I have put together this example. Note how I pass your XML to CFSavecontent, and then I pass the result of THAT to the XMLParse, and then I xmlsearch that. And it DOES work, producing a result and not throwing an error. (Note that one has to leave the opening ?xml element off when doing this. If instead, I had passed this XML to the CFXML tag, that WOULD accept the ?xml prologue line, and would negate need of using xmlparse, of course, as CFXML would turn the result into an xml object, inherently.)

(I'll add also that I don't have a CF9 readily available to try things--and I was not at my computer when I replied initially this morning, so I had not been able to test this then.)

If you try it as well, does it produce in the end the result you'd seen in CF9?

You might expirement with cfdump to see how to traverse the XML, but it is essentially a structure, so since GroupList is a child of SoapRequestResult and you want an array of Group tags (which is a child of GroupList, you should be able to get an array of Group tags with this:

xmlParseIn.XmlRoot["soap:Body"].SoapRequestResponse.SoapRequestResult.GroupList.XmlChildren
