story : Two objects are included here, a reader and a parser. All you need to do is instantiate
the xmlParser object and let it do the job for you. nextToken() will return the next
token, which can be a tag or the text between 2 tags. the isTag() will determine if this
is a tag so you can do something smart with it. Lastly you can jumpTo($tagname) if you
know the name of the tag you want to skip to. This can be "<p>" or something like "<div
class='menuItems'>" Run the example and enjoy.
