Can anyone help me with a regular expression that will return the end part of an email address, after the @ symbol? I'm new to regex, but want to learn how to use it rather than writing inefficient .Net string functions!
E.g. for an input of "test@example.com" I need an output of "example.com".
Cheers! Tim
This is a general-purpose e-mail matcher:
[a-zA-Z][\w\.-]*[a-zA-Z0-9]@([a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z])
Note that it only captures the domain group; if you use the following, you can capture the part proceeding the @ also:
([a-zA-Z][\w\.-]*[a-zA-Z0-9])@([a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z])
I'm not sure if this meets RFC 2822, but I doubt it.
