用php从xml文件中只读取第一个节点[关闭]

Question

我正在尝试将 xml 数据读入 php。我设法用这个 scipt 读取了所有“标题”数据。问题是我只需要 xml 中的第一个“标题”元素！不幸的是，我立刻得到了所有这些。 如何只读取第一个“标题”节点？

<?php

$filename = $_SERVER['DOCUMENT_ROOT'].'images/albums/album.xml';
if (file_exists($filename)) {
$doc = new DOMDocument(); 
$doc->load($filename); 
$destinations = $doc->getElementsByTagName("title"); 

foreach ($destinations as $destination) { 
    foreach($destination->childNodes as $child) { 
        if ($child->nodeType == XML_CDATA_SECTION_NODE) { 
            echo ('<br/><strong>Värskemad pildid:</strong><br/><a      href="/images/albums/index.html" src=""/>' . $child->textContent .  '</a>');
        } 
    } 
} 

} else {
die(nothing);
}
?>

我的 xml 看起来像这样：

<album version="v6">
<title><![CDATA[2012-06-06 NK maakondlik laager]]></title>

<slide>
    <title><![CDATA[2012 NK maakondlik laager 003]]></title>

试试：

<?php
$filename = $_SERVER['DOCUMENT_ROOT'].'images/albums/album.xml';
if (file_exists($filename)) {
$xml = simplexml_load_file($filename);
echo $xml->title[0];
} else {
die("nothing");
}
?>
