This is perhaps not an answer to your question, but it looks to me like you
don't really need a regexp for your match.
If all your expressions are as easy as in your example you could use

1> String =  "\\000\\005\\abc".
2> string:tokens(String,"\\").

In Erlang I most often find it easier to write a recursive function that
parses the string than to try to come up with the right regular expression.
