            This works just fine for me in the JSON Assertor: /root/item[Ancillary/Id/text()="67678"]/Transaction/detail/Amount/string() 0

            did you select value assertion option? or any other option as i could still see error saying not a valid xpath @banken_parasoft 0

            did you select value assertion option Yes, Value assertion or String assertion would work. i could still see error saying not a valid xpath The XPath is syntactically correct. Can you show the error? 0
