- * The SimpleXMLIterator implements the RecursiveIterator interface. This
- * allows iteration over all elements using foreach or an appropriate while
- * construct, just like SimpleXMLElement does. When using the foreach construct,
- * you will also iterate over the subelements. For every element which
- * has subelements, hasChildren() returns true. This will trigger a call to
- * getChildren() which returns the iterator for that sub element.
