after theNode, nextSibling returns null. In the following XML source fragment, the CONTENT

node is the nextSibling of the USER node:

<MESSAGE><USER>gray</USER><CONTENT>hi</CONTENT></MESSAGE>

Example

Typically, the nextSibling property is used to traverse (move through or examine) an XML

object hierarchy. For example, to view all the children of

theNode in the order they appear,

we can use:

for (var child = theNode.firstChild; child != null; child = child.nextSibling) {

trace("found node: " + child.nodeName);

}

By extending our loop into a function, we can recursively traverse every node in an XML

object hierarchy, as follows:

function showNodes (node) {

trace(node.nodeName + ": " + node.nodeValue);

for (var child = node.firstChild; child != null; child = child.nextSibling) {

showNodes(child);

}

}

// Invoke the function on our node or document

showNodes(myDoc);

Note that in both traversal examples shown, text nodes show up without a name, as

described under the

nodeName entry.
