Wendell,

Thank you very much for the reply.  I actually hadn't been aware of
the << and >> operators, I shall have to read up on them.  I did think
about using a for loop, I just wasn't sure how I could write one which
would be efficent, which wouldn't end up taking a lot more time than
necessary to run down the remaining following-sibling elements.

Thanks for the pointers, this gives me more things to research. :)
