使用php更新xml中的節點值

Question

這是我的xml文件。我想更新它。什麼是最好的方式來更新這個XML文件。就像影片的任何節點值在電影標籤，標題文件在標題標籤等

<?xml version="1.0"?> 
<gallerylist> 
    <record> 
    <movie>videos/Avatar_HD.flv</movie> 
    <title>Title:</title> 
    <desc>Description</desc> 
    <preview>videos/previews/avatar.jpg</preview> 
    <imgplaylist>videos/imgplaylist/p1.jpg</imgplaylist> 
    <category>Category</category> 
    </record> 
<record> 
    <movie>videos/The_Princess_And_The_Frog_HD.flv</movie> 
    <title></title> 
    <desc>fdgdd</desc> 
    <preview>videos/previews/frog.jpg</preview> 
    <imgplaylist>videos/imgplaylist/p4.jpg</imgplaylist> 
    <category>Category1</category> 
</record> 
    <record> 
     <movie>videos/Prince_of_Persia_The_Sands_of_Time_HD.flv</movie> 
     <title>Title:2</title>

     <imgplaylist>videos/imgplaylist/p2.jpg</imgplaylist> 
     <category>Category2</category> 
    </record> 
    <record> 
     <movie>videos/Sherlock_Holmes_HD.flv</movie> 
     <title>Title:4</title> 
     <desc>dfgdf</desc> 
     <preview>videos/previews/sherlock.jpg</preview>

退房用於處理XML文件的一些PHP庫。像這樣：http://www.php.net/manual/en/book.simplexml.php
