php - 文档末尾的 XML/PHP 额外内容

Question

我的 xml 中有错误（文档末尾的额外内容），我已经在整个互联网上进行了搜索，但没有任何解决方案有效。

我已经阅读了有关根目录或文档的内容，但并没有解决我的问题。

PHP：

<?php $doc = new DOMDocument('1.0', 'utf-8');
// we want a nice output
$doc->formatOutput = true;
$query = "SELECT * FROM leden";
while($q = mysql_fetch_assoc($query)) 
{ 
$user = $doc->createElement('user');
$user = $doc->appendChild($user);
$title = $doc->createElement('id');
$title = $user->appendChild($title);
$text = $doc->createTextNode($q['id']);
$text = $title->appendChild($text);
$title = $doc->createElement('nickname');
$title = $user->appendChild($title);
$text = $doc->createTextNode($q['gebruikersnaam']);
$text = $title->appendChild($text);
//etc.. etc
}
echo $doc->saveXML($doc);
?>

输出：

<?xml version="1.0" encoding="UTF-8"?>
<user>
<id>300</id>
<nickname>Peterjhonsen</nickname>

Answer 1

您需要所有用户的父母，例如：

<?xml version="1.0" encoding="UTF-8"?>
<userlist>
    <user>
        <id>300</id>
        <nickname>Peterjhonsen</nickname>
    </user>
    <user>
        <id>400</id>
        <nickname>Fred</nickname>
    </user>
</userlist>

只需在第 1 行之后插入：

$root = $doc->createElement('userlist');
$root = $doc->appendChild($root);

并相应地更改代码while：

...
$user = $root->appendChild($user);
