XML property aliasing

Question

I have a problem: I receive a XML file in my transaction input
<?xml version="1.0" encoding="UTF-8"?><DATA>
<VALUE_1/>
<VALUE_2/>
</DATA>
and I want to rename the property DATA with the name TAGS.
After this step, I want to access to the tag using Transaction.Source{/TAGS/VALUE_1}
Does anybody know how to do this?
I tried to use "Column aliasing" and "XSL Transformation" but without results. Which is the best way to do this?

Answer 1

I tried it, but like before XSL transformation doesn't work. Maybe I do something wrong in XSL transformation settings.
I added XSL transformation.
I didn't configure the transformation URL (Configure object button)
In configure links, Incoming tab, I set Inpux XML file as "Transaction.Source" (Source is my xml input file)
In configure links, Incoming tab, I set InputXSL copying your xsl code.
I didn't set xml output file, so less error appears.
The system gave me a list of errors:
[ERROR]: STEP EXCEPTION () : Invalid Variable In Expression: xml
[ERROR]: STEP EXCEPTION (XSL_Transformation_0) : Invalid Variable In Expression: xml
[ERROR]: STEP EXCEPTION (Sequence_0) : Invalid Variable In Expression: xml
[ERROR]: STEP EXCEPTION (Sequence) : Invalid Variable In Expression: xml
[ERROR]: TRANSACTION EXECUTION TERMINATED
Do you know which is the right configuration for XSL transformation?
I know just this help page: http://help.sap.com/saphelp_xmii120/helpdata/en/45/cca60593696f74e10000000a1553f6/frameset.htm
but it is very short.
Do you know other helpful webpages?
Thank you for your first answer.
