  I'm suspecting all you need is some training with regular expressions.
Start with the Llama book, the Camel book, or the Perl regular expressions
tutorial (http://www.perldoc.com/perl5.8.0/pod/perlretut.html) or quick
start (http://www.perldoc.com/perl5.8.0/pod/perlrequick.html).

  You should be able to keep that one line and break it up into separate
strings (try the split function) or use it over and over again with multiple
operations.  By and large, the presence of control characters and/or 8-bit
characters shouldn't interfere with this, but if you need to represent a
control character in a string or expression you can do so with for example
"\cX" to represent control-X.
