xpath query in php

Lets see the zend mock php 5 certification question on xpath.

Question:

Consider the following simple PHP script:


$dom = new DomDocument();
$dom->load('test.xml');
$xpath = new DomXPath($dom);
$nodes = $xpath->query(???????, $dom->documentElement);
echo $nodes->item(0)->getAttributeNode('bgcolor')->value
. "\n";

What XPath query should go in the ?????? above to display the "bgcolor" attribute of the first "body" node in the XML document?


Answer:

1. "*[local-name()='body']"
2. "/body[0]/text"
3. "/body/body[0]"
4. "name='body'"
I am not sure about this. my answer is this.
5. "*[lname()='body']"
