I'd like to suggest learning 'structured regular expressions' such as
used in lex / yacc (or flex / bison).  They build complex expressions
from simpler named expressions.  Sed / perl regular expressions are
seldom constructed from smaller components like this, although it's
quite possible to do it in perl at least.
