使用php仅从xml文件中读取第一个节点 [英] reading only first node from xml file with php

问题描述

我正在尝试将 xml 数据读入 php.我设法用这个 scipt 阅读了所有标题"数据.问题是我只需要来自 xml 的第一个标题"元素！不幸的是，我立即得到了所有这些.如何只读取第一个标题"节点?

I am trying to read the xml data in to php. I managed to read all "title" data with this scipt. Problem is that I only need first "title" element from xml! In moment I get unfortunatly all of them. How to read only first "title" node?

<?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:

My xml looks something like this:

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

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

推荐答案

尝试:

<?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");
}
?>
