This interface represents a read-only ordered
collection of nodes that can be interated through.
getLength( ) returns the number of nodes in the
list, and item( ) returns the
Node at a specified index in the list (the index
of the first node is 0). The elements of a
NodeList are always valid Node
objects: a NodeList never contains
null elements.Note that NodeList objects are
"live"they are not static but immediately
reflect changes to the document tree. For example, if you have a
NodeList that represents the children of a
specific node, and you then delete one of those children, the child
will be removed from your NodeList. Be careful
when looping through the elements of a NodeList if
the body of your loop makes changes to the document tree (such as
deleting nodes) that may affect the contents of the
NodeList!public interface NodeList {
