Regex to extract emails in WebHarvy

Question

I am trying to work up a Regex to extract email addresses off a WP directory using WebHarvy (.NET)

The emails could be in multiple formats, using dots and underscores and so I tried the following expressions

(\w+|\w+(\W|\.)\w+)@\w+.\w+
\w.+|\w+\S\w+@\w+\.\w+

Though they seem to be working in the Regexstorm tester, when I am using them in WebHarvy, they are only extracting the part preceding the @

Please advise

`\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b` – 0m3r Apr 27 '17 at 19:55 — 0m3r, Apr 27 '17 at 19:55

The problem is that WebHarvey returns the capturing group value. Since you wrapped the user part with a capturing group ((\w+|\w+(\W|\.)\w+)), it returns only that part.

You may fix your regex using a non-capturing group ((?:...)) as

(\w+(?:\W+\w+)*@\w+\.\w+)

or use a more generic

([^\s<>'"]+@[^\s<>'"]+\.[^\s<>'"]+)

The [^\s<>'"]+ will match 1+ chars other than whitespace, <, >, ' and " symbols. @ and \. match a @ and a . respectively.

Thanks Wiktor - I used `(\S*@\w+\.\w+)` but it returned emails as `value="example@example.com` – blackystrat Apr 27 '17 at 20:22
You should define context, like this: `value="([^\s"]+@\w+\.\w+)"`. Note that `\S` = `[^\s]`, any char but whitespace, and you may further restrict it by adding chars/ranges. You might even find `([^\s<>'"]+@[^\s<>'"]+\.[^\s<>'"]+)` a better alternative. – Wiktor Stribiżew Apr 27 '17 at 20:24

Thanks a lot, Wiktor – blackystrat Apr 28 '17 at 12:30
`([^\s<>'"]+@[^\s<>'"]+\.[^\s<>'"]+)` this works perfectly. Sorry for the late response. Thanks – blackystrat Apr 28 '17 at 18:55
