Regular expression to match email addresses
I am trying to validate a TextEdit in order to contains a truly email address. I have a regular expression to do that, but it validates mor开发者_JAVA技巧e than one address, and I just want to validate only one address, no more.
Here you are the expression I have:
/^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,3})$/
It validates something like this:
yulien.paz@cav.desoft.cu, wcampbell@cav.desoft.cu
I need take the second email address out of the TextEdit.
So, How can I do that??
Note: I am sorry about my English.
Here a great library of regular expressions
http://regexlib.com/Search.aspx?k=email
And tester of regexp.
This is a sample http://regexlib.com/REDetails.aspx?regexp_id=88
^([\w-.]+)@(([([0-9]{1,3}.){3}[0-9]{1,3}])|(([\w-]+.)+)([a-zA-Z]{2,4}))$
In order to find email address inside a paragraph, none of the the above works. Instead you need to look for word boundary, ex.
\b[_\S\d-]+@[_\S\d-]+\.[\S]{2,3}\b
And then use /g if needed.
Try this
/^([a-zA-Z0-9_.-])+@(([a-zA-Z0-9-])+.)+([a-zA-Z0-9]{2,4})+$/
