help in a regular expression extraction

[royimad]

I have a text that contains anything followed by a word that start with either
XPOS, POS and HF and ended by -

Example:
ABC XPOS2024 -
DEF POS340903 -
GHI HF3948329 -
...

How to extract XPOS2024 , POS340903 , HF3948329 using regular expression?

You may try below regex as well:
"(?:)[^ ]+ +(?P(XPOS|POS|HF)[^ ]+) +-"

If it does not work please let me know.

Thanks man

try this on the search : (and remove the underscored, they are here to trick the html formatting)


* | rex "(?<myfield>(XPOS|POS|HF)\d+)" | table myfield


[royimad]

It's working great thank you guys

Thanks Åynm I had a missing parenthesis.

And if the characters after are not always digits, disha's regex is perfect.

* | rex "(?<myfield>(XPOS|POS|HF)\d+)" | table myfield

[royimad]

it seems that this isn't working
