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

Answer 1

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.
