在PHP5中使用DOM控制XML(2)
时间:2008-05-19 来源:剑心通明
//向DOM中写入新数据
$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);
//从DOM中删除节点
//$dom->documentElement->RemoveChild($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 = $xpath->query("/rss/channel/item/title")->item(0);
//$firstTitle->setAttribute("orderby", "4");
$dom->save("newfile.xml");
echo "查看newfile.xml";
//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;
*/
?>
下面是test.xml文件代码:
