ここから開始できますhttp://www.php.net/manual/en/simplexml.examples-basic.php

PHP を使用した簡単な例:

<?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);
?>

編集：Jqueryで

Xml ファイル構造が

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

JQuery を使用して、 $.ajax() メソッド:

 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
            })
        }  
    });

jquery ファイルをヘッダーに含めることを忘れないでください。

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