What if you’re willing to transform an array object attribute into a string? In this video, Lorenzo would like to share his “How(s) to” with you.

Hi Lorenzo! The reason why the equal is not working is the same that you are getting a warning. Keys in DataWeave are not Strings but rather a different data structure that is formed of a QName and attributes. So as you mentioned you can cast a Key to a String or you can use the similar comparator key ~= "surname". This has nothing to do with the type of the payload as in DataWeave it doesn't matter if the payload is Json XML Excell or whatever it is always represented in the cannonical representation. BTW Thanks for posting the video
