Use DOM to control XML in PHP5 (2)

Use DOM in PHP5 to control XML (2) // write new data to 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 );

// Delete a node from the DOM
// $ Dom-> documentElement-> RemoveChild ($ dom-> documentElement-> getElementsByTagName ("channel")-> item (0 ));
// Alternatively, use xpath to query the nodes and then delete them.
// $ Dom-> documentElement-> RemoveChild ($ xpath-> query ("/rss/channel")-> item (0 ));
// $ Dom-> save ("newfile. xml ");

// Modify node data from the DOM
// Modify the file of the first title
// This place is stupid. create a new node and replace the old one. If any of your friends has other good methods, please tell me.
$ FirstTitle = $ xpath-> query ("/rss/channel/item/title")-> item (0 );
$ NewTitle = $ dom-> createElement ("title ");
$ NewTitle-> appendChild (new DOMText ("This's the new title text !!! "));
$ FirstTitle-> parentNode-> replaceChild ($ newTitle, $ firstTitle );
// Modify attributes
// $ FirstTitle = $ xpath-> query ("/rss/channel/item/title")-> item (0 );
// $ FirstTitle-> setAttribute ("orderby", "4 ");
$ Dom-> save ("newfile. xml ");

Echo" View newfile. xml ";

// The following code retrieves and parses the php.net homepage and returns the content of the first title element.
/*
$ Dom-> loadHTMLFile ("http://www.php.net /");
$ Title = $ dom-> getElementsByTagName ("title ");
Print $ title-> item (0)-> textContent;
*/
?>
