Extracting a substring from Line
Hi All

I have a line which is as below

Code:
1234567          Gagan Paswani zz23432 1000000000      1000000000      ASTHEYXX-RTUC zz23432

I need to extract the first occurence of zz23432 which will have the reg expression as
Code:
[a-z]{2}[0-9]{5}

Could you please assist as to how I can extract this field from the line?
