in reply to regex - parsing a string with many optional fields

Well, it doesn't look like you are making any decisions based on what type of duration is being read, so why not simplify it, e.g:

my @temp = $str =! /([PT]\d+[YMWDHMS])/g;

    Note that this will not actually finish the parsing. Once the string has been broken out into its component parts (which this will do), more work needs to be done in order to properly understand the string.
