Question

我正在尝试使用PHP DOM将数据插入到我的RSS xml文件中。这些是涉及的代码。

的index.php

<html>
<head><title>test</title></head>
</head>

<form name="input" action="insert.php" method="post">
    insert item:
    <input type="text" name="item"/>
    <input type="submit" value="send"/>
</form>
</body>
</html>

insert.php

<?php
header('Location:index.php');
$xmldoc = new DOMDocument();
$xmldoc->load('sample.xml');

$newAct = $_POST['activity'];

$root = $xmldoc->getElementsByTagName('channel')->item(0);

$newElement = $xmldoc->createElement('item');
$root->appendChild($newElement);
$newText = $xmldoc->createTextNode($newAct);
$newElement->appendChild($newText);

$xmldoc->save('sample.xml');
?>

sample.xml中

<?xml version="1.0" encoding="ISO-8859-1"?>
<rss xmlns:atom="http://www.w3.org/2005/Atom" version="2.0">

<channel>
  <title>Bagnista Home Page</title>

  <atom:link href="example.xml" rel="self" type="application/rss+xml"/>

</channel>

</rss>

由于我使用的是appendChild，因此item标记将位于last / item标记的下方。如何在第一个商品标签之前插入商品标签？我已经尝试过insertBefore（）但是它失败了。
