String Manipulation

I am a little new to procmail...

I am trying to take only the email address part out of the..
From:   line.
I figured out how to use
* MYFROM ?? ()\/<.*
to get the entire from line after ther first < sign, but this also includes
the < sign and the > sign along with the trailing end of line character.

does anyone know how to chop off the < and > so I can just get
someone(_at_)somewhere(_dot_)com?

Thanks
