XML question about DOM XML

[acidbox]

I was reading the DOM XML/PHP tutorial and ran across a stumbling block. Perhaps someone can help...

Assume My XML were the following:

<result>	
	<elememnt>
		<library>
			<book>
				<title>Hannibal</title>
				<author>Thomas Harris</author>
				<genre>Suspense</genre>
				<pages>564</pages>
				<price>8.99</price>
				<rating>4</rating>
			</book>

		<book>
			<title>Run</title>
			<author>Douglas E. Winter</author>
			<genre>Thriller</genre>
			<pages>390</pages>
			<price>7.49</price>
			<rating>5</rating>
		</book>

		<book>
			<title>The Lord Of The Rings</title>
			<author>J. R. R. Tolkien</author>
			<genre>Fantasy</genre>
			<pages>3489</pages>
			<price>10.99</price>
			<rating>5</rating>
		</book>

	</library>
</element>
</result>

How would I get the children from <library>? I see from the example, how a single teir XML document, with <library> being the root how it is done, but I cannot figure out how to jump multiple teirs.. Thanks in advance...

basically I want to shift the array to the children's children. anyone?

Give this a try...
// gets the root node, in this case, <result>
$nodes = $root->children();
// Index 0 would be the element node
$nodes = $nodes[0];
// Now $nodes should contain all the library nodes
// now you can iterate through <library> nodes
for ($x=0; $x<sizeof($nodes); $x++)
{
echo "<tr>";

// check type
// this is to correct whitespace (empty nodes)
if ($nodes[$x]->type == XML_ELEMENT_NODE)
{
  $thisNode = $nodes[$x];

...

}

I guess you could also use the function:

$librarynodes = get_elements_by_tagname("library");
