Compare date on licence file

[coda_matt]

I'm trying to check the expiry date of some licence files, with this format:

FEATURE simulator
{
VENDOR=COMPANY COUNT=2000 VERSION=1.0 START=2023-01-12 END=2023-12-12 SHARE=VIRTUAL
LICENSEE="Company  (C49_2265_2231)"
KEY=random string \
    random string \
    random string
}​

I've created my own template, and the vfs.file.regexp item seems like it should work, but I need to extract the END= date and compare the date.

Is there a good example that I can copy?

Thanks

Much FlexLM experience here. Not so much Regex.
I'm going to do a link dump and continue editing this reply as I figure out the whats and hows.
