Solution

  • You might be better off converting to JSON and working with the data in that format. At least you can get rid of all the silly namespace complexities that way.

    LogicApps is JSON focused internally so doing so would be slightly more 'correct' anyway.

    You can find samples at: JSONPath - XPath for JSON

    And an evaluator: JSONPath Online Evaluator
