Well, there are at least two alternatives.  If you want to stick with
the idea of using regexps then there is a function called
delete-matching-lines which is probably what you want. 

A specific way of doing what you want with blank lines is to remove all
occurrences of the string ^J^J (i.e.  a blank line consists of the
string newline-newline)
