Dear Experts ,
Need experts advice to extract "ABC6_IN_S14093456789" from below information which is available in field. I think Regex could be used to extract that filed. your help is appreciated.

 <Hdr Id="[ABC6_IN_S14093456789]-a411655e-069c-4ce5-b2d1-b0c22f54c4a3" Ver="0.001" Dtm="2019-05-02T15:59:55Z" TmOff="-07:00" />

Please try below . (The logic is to say greedily collect all characters until it finds ]

Id=\"\[(?P<my_id>[^\]]+)\]

Demo in Regex101

So in Splunk it would be (assuming _raw is your event)

 | rex "Id=\"\[(?<my_id>[^\]]+)\]"

In Splunk P is not needed, so can write:

  | rex "Id=\"\[(?<my_id>[^\]]+)\]"

I think ] does not need to be escaped between [], so this should also work

  | rex "Id=\"\[(?<my_id>[^]]+)\]"
