Try working with while($it->valid()....
Besides that SimpleXMLIterator implements the RecursiveIterator interface.
What it does is iterating over one element and if teh element has sub
elements then hasChildren() returns true and getchildren() returns the
iterator for that sub element. To see what's going on have a look at
ext/spl/tests/sxe_00*.phpt.
