Need help with a complicated field-extraction via regex

[AnujaJadhav2]

want to extract a field in splunk however Splunk Regex won't work so I am writing my own Regex. However I am struggling to extract. Can someone please help?

My String:

Node ID=nbgcXYZdfdscxm2
Node ID=NBGDFDFCCXM2
Node ID=BURECXM2

Expected Output:

cXYZdfds
DFDFC
BURE

So far I was able to write this .*(?i)Node ID=^nbg

This worked for me (validated using regex101.com):

(?i)Node ID=(nbg)?(?P<thing>\w+)cxm\d+

Just Perfect. Cannot imagine I wasted hours around this. Thank you so much.

Hi AnujaJadhav2,

using regex101.com I ended up with this or regex:

 Node ID=(?i:(nbg))(.+)(?i:(cxm\d))|Node ID=(.+)(?i:(cxm\d))

the capturing group (.+) gives you the required results.

I'm sure this is not the best solution regex wise and some more clever guys haver better regexes, but it gives you something to start with 🙂

cheers, MuS

This works very well in regex101 but it needs a capturing group for extraction. Nevertheless, thank you so much for your help.
