HTTP Get and XML Fetc

I'm using the HTTP resource control, It access a web services with the Get command(Http request type). For example: <a href="http://127.0.0.1/WS/GetName?Id=1 " target="_new">http://127.0.0.1/WS/GetName?Id=1 </a> After that step I performed a XML Load. They both finalized sucessfully. But when I performed the XML Fetch, it shows this error "Warning: Node has no attributes FAILURE". For example, if the xml is: <?xml version="1.0" encoding="utf-8" ?> <RESPONSE> <NAME>Card Balance</NAME> </RESPONSE> How can I fill the XML Fetch control to obtain the name data. I have tried: ---------------------------- XML_HANDLE=022 NODE= RESPONSE->NAME VARIABLE TO REC DATA= @LCLNAME --------------------------- XML_HANDLE=022 RESPONSE->NAME AS LCLNAME --------------------------- XML_HANDLE=022 NODE= RESPONSE NAME AS LCLNAME --------------------------- The problem is that they failed. How can I store the result in the LCLNAME variable? Thanks

The first of your fetch examples was correct. This is actually a problem with the XML Fetch step. This issue (Failure due to empty attributes field) will be fixed in an upcoming release of TeleFlow. In the meantime, you have two possible workarounds: 1) You can create some false attributes in the node you are fetching, and retrieve them. Sample XML for this: <?xml version="1.0" encoding="utf-8" ?> <RESPONSE> <NAME UNUSED="UNUSED">Card Balance</NAME> </RESPONSE> Attributes field: UNUSED This will create a variable called @UNUSED, but will work. 2) Put "UNUSED" in the attributes field. This will cause the step to go down the FAIL path when it tries to retrieve the attribute that isn't in the XML document. You can route the FAIL (bomb) path of the XML fetch to a Compare step. Use that compare to see if the node was empty. If it is empty, assume the fetch failed for some reason other than the attribute problem, or that the node was indeed empty. If it is populated with data, this simply means the step failed because of the missing attribute. You should create the empty local or global variable to receive the node data prior to the XML Fetch.

The current release version of TeleFlow addresses this issue. You can now have an empty attributes field, and still run the XML Fetch to retrieve the nodes you are looking for.
