* DOM_NodeIterator
or DOM_TreeWalker
is given a
* filter, it applies the filter before it returns the next node.
*
* If the filter says to accept the node, the iterator returns it; otherwise, the
* iterator looks for the next node and pretends that the node that was rejected
* was not there.
*
* The DOM does not provide any filters. Filter is just an interface that users can
* implement to provide their own filters.
*
* Filters do not need to know how to iterate, nor do they need to know anything
* about the data structure that is being iterated. This makes it very easy to write
* filters, since the only thing they have to know how to do is evaluate a single node.
* One filter may be used with a number of different kinds of iterators, encouraging
* code reuse.
