Class NodeListIterator

java.lang.Object

net.sf.practicalxml.util.NodeListIterator

All Implemented Interfaces:

Iterator<Node>

public class NodeListIterator
extends Object
implements Iterator<Node>

A wrapper for NodeList that provides full iterator behavior. See NodeListIterable if all you want to do is use the NodeList in a JDK 1.5 for loop.

Because a NodeList is a view on a DOM tree, this iterator has slightly different semantics than a typical java.util iterator. First, it is not "fail fast": the DOM consists of independent nodes, and we have no way to track when changes to the DOM may have made the nodelist invalid.

Second, and more important, removal via the iterator changes the DOM, not just the underlying list.
