attention	The Selector data structure is a LIFO (Last in, First out). This is because CSS selectors are best processed "bottom up". Thus, when iterating over 'a>b>c', the iterator will produce: c b a It is assumed, therefore, that any suitable querying engine will traverse from the bottom (`c`) back up.
b	Usage This class is an event handler. It can be plugged into an Parser and receive the events the Parser generates. This class is also an iterator. Once the parser has completed, the captured selectors can be iterated over.
code	<?php $selectorList = new \QueryPath\CSS\Selector(); $parser = new \QueryPath\CSS\Parser($selector, $selectorList); $parser->parse(); foreach ($selectorList as $simpleSelector) { // Do something with the SimpleSelector. print_r($simpleSelector); } ?>
