OK so what is the regex to capture the piece of text that starts with space and ends with the end of the line and can contain any character?
-kalos
That would look like this:
.*\s+(\S+)$
What this does is:
.* : Any character
\s+ : white-space, 1 or more consecutive
( : start group
\S+ : not white-space, 1 or more consecutive
) : end group
$ : end of line marker
You will have to get the group 1 value for your result, input like this:
a piece of text at the end of the line
will give you the word 'line' as a result
If you are still searching for your original request, I took the first regex from
https://emailregex.com, dropped it in the
https://regex101.com regex tester, fixed the issues it reported (escape a few slashes because of the PCRE regex engine), and wrapped it with the construction I just showed here, and came up with this:
.*\s+((?:[a-z0-9!#$%&'*+\/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+\/=?^_`{|}~-]+)*|"(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])*")@(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?|\[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-9]:(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])+)\]))$
If you feed that this text:
test for email address with plain text prefix test@email.com
The only group that's there produces '
[email protected]' as a result.
Did I complete your assignment with this?
