DOMNodeLists are created by DOMDocument::getElementsByTagName(), DOMNode::getChildNodes(),

The items in the [DOMNodeList](classDOMNodeList.html "The DOMNodeList interface provides the abstraction of an ordered collection of nodes.") 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.

DOMNodeList::DOMNodeList ( )	protected

◆ ~DOMNodeList()

virtual DOMNodeList::~DOMNodeList ( )	virtual

Destructor.

◆ getLength()

virtual XMLSize_t DOMNodeList::getLength ( ) const	pure virtual

Returns the index item in the collection.
