Excellent, thanks - out of interest though, can it be done with a single regexp?

    A single regex cannot generate a variable number of backreferences. What do you think this is, Java? 1{grin}

    1The Java regex library I saw caused /(\w+)\s+)+/ to generate a variable number of backreferences, making it impossible to know exactly what part of the match you were looking at. Evil. They just don't get it.
