Hi Monks, I need a lil' help with this text manipulation

I've got names in a list like the following:

Bob Builder Tinky Winky Bugs Bunny Mickey Mouse

and ive basically got put them on separate lines. I think split can do this, and will store it in an array which is what i want but i have no idea how to split every other word?. I was also wondering if anybody knows how to remove spaces from the end of words

so if i had "hello " it would give me "hello"...will s// /; do it?

Thank you all
