The code is as follows:
/*



11
content1
2009-10-11


title2
content2
2009-11-11


*/
if (!function_exists('l')) {
function l() {
echo '
****************************** **********
';
}
}
if(file_exists('test10_12.xml')) {
$xml = simplexml_load_file('test10_12.xml');

//Use the xpath method to find the node location
$query = $xml->xpath('//title[@name="t1"]/ancestor::item');

var_dump($query);
l( );

//Test to add a new child node under the title node new
$query[0]->title->addChild('new','new');

//Test to add a new child node under the title node Add attribute fuck
$query[0]->title->addAttribute('fuck','fuck you');

//Test modify the content node value to hello,world
$query[0]-> content = 'hello,world';

//No explanation, you know
$query[0]->asXML("10.xml");
}
?>
