The problem with regex in java is that you have to further escape each
'/' with yet another. This results in absolutly unintelligable regular
expressions. I suggest that you look to the Java API under the Pattern
and Matcher classes.
When you find that it is very difficult to produce intelligable RE, a
good idea would be to write a program to convert unescaped REs to the
escaped vesrsion that Java needs.
