您可以从这里开始http://www.php.net/manual/en/simplexml.examples-basic.php

PHP 的简单示例：

<?php
$xml = '<?xml version="1.0" encoding="UTF-8" ?> 
<rss> 
 <channel> 
    <item> 
        <title><![CDATA[Tom & Jerry]]></title> 
    </item> 
 </channel> 
</rss>'; 

$xml = simplexml_load_string($xml); 

$myFile = "testFile.txt";//text file path
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = $xml->channel->item->title; 
fwrite($fh, $stringData);
fclose($fh);
?>

编辑：使用 Jquery

如果 XML 文件结构是

<item>
   <subject></subject>
   <date></date>
   <thumb></thumb>
</item>

使用 JQuery，$.ajax() 方法：

 var tmpSubject, tmpDate, tmpThumb;
        $.ajax({
        url: '/your_file.xml',
        type: 'GET', 
        dataType: 'xml',
        success: function(returnedXMLResponse){
            $('item', returnedXMLResponse).each(function(){
                 tmpSubject = $('subject', this).text();
                 tmpDate = $('date', this).text();
                 tmpThumb = $('thumb', this).text();
                //Here you can do anything you want with those temporary variables
            })
        }  
    });

请记住在标头中包含 jquery 文件：

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
