Using DOM to control XML in PHP5 (2)

Tags xpath
Writing new data to the DOM
$item = $dom->createelement ("item");
$title = $dom->createelement ("title");
$titleText = $dom->createtextnode ("title text");
$title->appendchild ($titleText);
$item->appendchild ($title);
$dom->documentelement->getelementsbytagname (' channel ')->item (0)->appendchild ($item);

Remove a node from the DOM
$dom->documentelement->removechild ($dom->documentelement->getelementsbytagname ("channel") Item (0));
Or use XPath to query out nodes and then delete
$dom->documentelement->removechild ($xpath->query ("/rss/channel")->item (0));
$dom->save ("Newfile.xml");

Modifying node data from the DOM
Modify the file for the first title
This place is stupid, create a new node, and replace the old node. If a friend has any other good ways, please tell me.
$firstTitle = $xpath->query ("/rss/channel/item/title")->item (0);
$newTitle = $dom->createelement ("title");
$newTitle->appendchild (New Domtext ("This ' s new title text!!!"));
$firstTitle->parentnode->replacechild ($newTitle, $firstTitle);
modifying properties
$firstTitle = $xpath->query ("/rss/channel/item/title")->item (0);
$firstTitle->setattribute ("by", "4");
$dom->save ("Newfile.xml");

echo "
The following code obtains and parses the first page of the php.net, returning the contents of the title element.
/*
$dom->loadhtmlfile ("http://www.php.net/");
$title = $dom->getelementsbytagname ("title");
Print $title->item (0)->textcontent;
*/
?>

Here is the Test.xml file code:
