How to identify email address at the end of lines with RegEx?

<< < (2/4) > >>

kalos:
I don't understand, the below matches " text1 text2 [email protected]".

Why does it includes spaces in between since it is enclosed in \b?


--- --- \b(.+?\.com)\b

Ath:
Why are you trying to use something you don't know how to construct (you are not even checking for the mandatory @ and .  >:(), if there are several working examples and links in posts above yours? Please use the advice that's given, for free, by ppl that actually know what they are talking about.

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?

--- End quote ---
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 linewill 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? ;)
