How to parse inline XML, encoded in Base64?

Hi!

I have to test response XML which contains normal data and also another XML encoded in Base64. This inline XML contains data I have to check.

For example, I receive:

I can easily check if session (or XMLname or reportName) match expected values, but I can't figure out how to check value of nmr_kods which is in encoded XML (here ir simple decoder http://www.hcidata.info/base64.htm ).

I've tried to write Groovy script and I managed to get value in Base64, but i failed to decode and parse it.

Thanks in advance, hope this topic will be useful for people in the future.

Best regards,
