Writing a new file from datasink for each iteration instead of appending

You can use the holders getXml() method to get the String representation fo the xml, and then write that to the file e.g.

def response = holder.getXml()
file << response

Note: the above code will append the response to the file if it already exists, so you might want to ensure that it is empty.

If the you want a new file for each iteration, use a random number in the name of the file, or the number of the iteration.

BTW, to ensure prompt response, please post in the SoapUI Pro forum

Good luck!
