Index of object in array found with match response[*]

Is it possible to get the index value of a * match response.Services[*] contains { "Service": "xyz"}

I'm looking to reuse it later for more specific tests on the same Service object. Theres reference to a __loop variable here but I guess I don't really understand how to apply it.

I love your questions, you are certainly pushing Karate to the limits and I'm having to think hard to answer these as well :)

The match does not allow you to get the "found index" or even the "loop position" which come to think of it - may be actually relevant for a match each - but I digress.

This will take a few extra lines of code, and I really think you need to upgrade to 0.8.0. If it helps, I can confirm that there are no breaking changes (unless you use the stand-alone JAR).

The new karate.forEach() and karate.match() functions allow you to do very complex operations on arrays. Here are 2 examples:

Scenario: karate find index of first match (primitive)
    * def list = [1, 2, 3, 4]
    * def searchFor = 3
    * def foundAt = []
    * def fun = function(x, i){ if (x == searchFor) foundAt.add(i) }
    * eval karate.forEach(list, fun)
    * match foundAt == [2]

Scenario: karate find index of first match (complex)
    * def list = [{ a: 1, b: 'x'}, { a: 2, b: 'y'}, { a: 3, b: 'z'}]
    * def searchFor = { a: 2, b: '#string'}
    * def foundAt = []
    * def fun = function(x, i){ if (karate.match(x, searchFor).pass) foundAt.add(i) }
    * eval karate.forEach(list, fun)
    * match foundAt == [1]

If you really can't upgrade, you can write a function to manually loop over the array and the above examples should get you a solution.
