DOMNode::getNodePath — Get an XPath for a node
Gets an XPath location path for the node.
此函数没有参数。
Returns a string containing the XPath, or NULL in case of an error.
Example #1 DOMNode::getNodePath() example
<?php
// Create a new DOMDocument instance
$dom = new DOMDocument;
// Load the XML
$dom->loadXML('
<fruits>
<apples>
<apple>braeburn</apple>
<apple>granny smith</apple>
</apples>
<pears>
<pear>conference</pear>
</pears>
</fruits>
');
// Print XPath for each element
foreach ($dom->getElementsByTagName('*') as $node) {
echo $node->getNodePath() . "\n";
}
?>
以上例程会输出：
/fruits /fruits/apples /fruits/apples/apple[1] /fruits/apples/apple[2] /fruits/pears /fruits/pears/pear
