Thanks for your answer deepesh.jain!
I think I understand the mechanics, but I'm not sure if I have to do something with the request step "Publication of data". That is, it assumes that the text that was selected in the attached image (in my previous post) has to be deleted and there will be the XML text (the content of the file that is been reading). Do I have to put in there "something" to indicate that in this space there is what the script groovy populates?
The statement that you put before:
<<requestSet.getProperty("request").setValue(setXML);>>
I'm not sure what it does. Does this fill the entire contents of "Publication of data"? how indicates that this have to fill only part of the text I want to replace for each XML file content?
Forgive me if I make basic questions, I would like to had more time to view tutorials and general info about the programa and Groovy Script, but I started yesterday with this program and I need to perform these tasks for my job
PD: sorry for my poor english
