Extract Last 12 Characters

IRHM73 — Wed, 17 May 2017 11:47:22 GMT

Hi, I wonder whether someone could help me please.

I have the following string, which I'm trying to extract the last 12 characters i.e. A1B-CDEFB-NOT

claim-a-token|N5Y-UWLB-NOT

I've tried using the following regex /|(?[^\s]+) but unfortunately it extracts the whole string and not just the last 12 characters, and I'm a little unclear why.

Could someone perhaps look at this please and offer some guidance on where I've gone wrong.

Many thanks

Chris

Hi IRHM73,
if you haven't spaces in your string, this is your regex:

(?<field>[^ ]{12})$

if instead you have spaces in your string, you could use this regex:

(?<field>.{12})$

Bye.
Giuseppe
