//$dom->documentelement->removechild($dom->documentelement->getelementsbytagname("channel")->item(0));
//或者使用xpath查询出节点再删除
//$dom->documentelement->removechild($xpath->query("/rss/channel")->item(0));
//$dom->save("newfile.xml");
//从dom中修改节点数据
//修改第一个title的文件
//这个地方比较笨,新创建一个节点,然后替换旧的节点。如果哪位朋友有其他好的方法请一定要告诉我
$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);
//修改属性

//$firsttitle->setattribute("orderby", "4");
$dom->save("newfile.xml");
echo "<hr/><a href=\"newfile.xml\">查看newfile.xml</a>";
//下面的代码获得并解析php.net的首页,将返第一个title元素的内容。
/*
$dom->loadhtmlfile("http://www.php.net/");
$title = $dom->getelementsbytagname("title");
print $title->item(0)->textcontent;
