Yes, but the number is different depending on the success or failure of the
login. My instinct is to add logic to determine that success/failure first, then
go find the node I need. Or, I'll see if I can use the technique in that blog to
make it more compact.
Thanks for pointing that out, Casey. (And thanks, Ben, for writing it).

Yes, that's as good as it'll get if that's the structure of your XML
document, I think.

Do you always know how many children will be returned for a specific node?
If not you want to check this out. It will loop over children and you can
work specifically with those items.

Thank you, Dave.

Great! I was searching for a component like that, and I never came across this
one; just the two old ones that the author references.

I see. Going by the names of the nodes makes sense, and it's easier to
read/manage. In that case, I've got this:
<cfset local.loginResponseSID =
local.requestXMLObject.methodResponse.params.param.value.struct.member.value.string.xmlText
/>
Is that the simplest/cleanest that this is going to get?
Much appreciated.

First, have you looked at this?

Almost certainly. In general, you can simply refer to XML elements as
nested arrays and structures, using the names of the elements; if
they're repeated within a single parent, you use array notation to get
to the one you want.
So, if you had a document like this in myXmlObj:
<xmldoc>
<child>
<grandchild>value1</grandchild>
</child>
<child>
<grandchild>value2</grandchild>
</child>
</xmldoc>
you could get to "value2" using:
myXmlObj.child[2].grandchild.xmlText
(Actually, since it's nearly 3am, I could very well have a minor error
in that, but the basic point stands.)

Hi, folks.
I'm retrieving an XML packet from an API that uses the XML-RPC standard (http://www.xmlrpc.com/spec).
When I connect to the Login method of this API, I need to pull the session ID out
of the packet. I can do that long-hand with this:
<cfset local.loginResponseSID =
local.requestXMLObject.XMLRoot.XMLChildren[1].XMLChildren[1].XMLChildren[1].XMLChildren[1].XMLChildren[1].XMLChildren[2].XMLChildren[1].XMLText
/>
But, there must be a cleaner way to do this, right?
A note: the node that I am looking for is called <string>, BUT, if the
login fails, there are multiple nodes called <string> in the response, so I
can't do an XMLSearch for "//string[.]" and get just the one I need.
FYI, the specific API that I am hitting is for iThenticate and the example is on
page 16 of this PDF:
https://ne.edgecastcdn.net/800404/static.ithenticate.com/static/build/media/e356a7e98a516945bba0af5293e8eb48cb_iThenticateAPIGuide.pdf)
Any help to streamline this is much appreciated.
