Xquery in a groovy

Doesn't answer the question, but it might be easier to use a Property Transfer step to move your desired content to a Property step, then either use Groovy to write the value out to a file, or configure the Property step itself to write to a file.

Thanks anyway. But what I was looking for was to create an XML file using an XQuery to extract certain information of my original xml response.

I found the way to do it using mxquery.jar. You may check http://www.mxquery.org.

I guess I didn't understand your need. I'd be curious to know more details of what you were trying to do.

Well, I'm testing two versions of a WS. There are a lot of information in my responses and some of them change dinamically everytime, so I can not compare both responses as is. So, I running an Xquery on my responses to extract only the information I need and should be the same in both, save it to a file and then compare both files.
