preg_split() Help

Hi All. I'm having a bit of a problem with a regular expression for preg_split(). I was hoping someone can give me a hand. I'll have an input line like this -- <$World> blah <$ Wide> blah <$ Web > I need a regular expression to parse this and give me an array of ("World", "Wide", "Web"). What's throwing me for a loop at the moment is the optional spaces before/after the <$ and > delimiters. These spaces may or may not be there for any of the 'fields'. For that matter there could be from 1 to n 'fields' in the input. Anyone care to straighten me out? Thanks! -Steve.
