Is there a way such that I can use the Process to store it as a string without resorting to using a shell to execute the command, store it as a text file, read its contents then removing the temporary text file?

Now I need all Keys with value "1". It is possible to extract them without a for loop?

each node needs ALL nodes from the upper levels to check.

Simple example:

[$0001][00]
[$0002][01]
[$0003][04]
[$0004][01]
[$0005][02]

Recursion - check element and its connectors

1. 0001 - my for loop checks all connectors -> Result: 0002 and 0004 (because Key is 01).

2. now check the connectors for connectors (we have 0002 and 0004)
3. 0002 has 0005(key = 02)
