How to remove a subfield

Question

Pretty simple. For example:

OBX|1|FT|This^That|

How do I remove "This" and leave just "^That"

 

Thanks in advance!

Answer 1

message.setNode('OBX-3', message.getNode('OBX-3.2'));

That did it, what would be the cleanest way to add  back the carrot so it's: ^That

My first update would basically wipe out OBX-3 and replace it with just the value from OBX-3.2 but if you just wanted to blank out OBX-3.1 you could do this.

message.setNode('OBX-3.1', '');
