Hello guys, my question is if there is a way to ignore a MERGE-line if a variable "if not exists". I have many xml-Files with some fields that dont exist in all my files, so I have to think about a solution with an option to ignore MERGE-Code. Ex...

This is good, it worked like I wanted. Now I have to do this for all the values. Overall my plan is it to "traverse" the file and create Nodes/Properties, but not with every value. For example I dont want the milestonelist as a Node, BUT I need all t...
