XML DOM - The NodeList Object
The NodeList object represents an ordered list of nodes.
The NodeList object
The nodes in the node list can be accessed through their index number (starting from 0).
The node list keeps itself up-to-date. If an element is deleted or added, in the node list or the XML document, the list is automatically updated.
Note: In a node list, the nodes are returned in the order in which they are specified in the XML document.
