Regex for extracting e-mail addresses

[leuce]

Hello everyone

Does anyone know what is the regular expression (in AutoIt syntax) for extracting e-mail addresses?

Thanks

I'm not sure of the exact rules, but I think each email address must:

• Not contain spaces
• Contain an @
• Contain a period with an ending (ie: .com, .org, .edu, etc)

So you could use something simple like this:

([^\s]*@[^\s]*\.[^\s]*)

Wikipedia says quite enough about the syntax of an email address, so, other than providing some real-World example you are working with, why don't you show us what you tried?

I could do that, of course, but how would I (or you) know of the regex is any good?  Even if it manages to extract *some* e-mail addresses would not be proof that it is the proper regex for extracting *all* e-mail addresses.  The whole point of using the correct regular expression is to avoid using an expression that works only in test cases.  Are you saying that you'll tell me the correct answer only after I've given you some likely incorrect attempts? :-)
