Detailed Description
The DOMNodeList interface provides the abstraction of an ordered collection of nodes.
DOMNodeLists are created by DOMDocument::getElementsByTagName(), DOMNode::getChildNodes(),
The items in the DOMNodeList are accessible via an integral index, starting from 0.
DOMNodeLists are "live", in that any changes to the document tree are immediately reflected in any DOMNodeLists that may have been created for that tree.
