Hi there!

Im currently working on a script which allows me to enter new posts in a XML-file.

The XML ("config.xml") is read by a flash application to show videos. The XML-template is as follow, and is entered for each new movie I want to publish:

      <item>
         <title>$title</title> // from form ($_POST)
         <description><![CDATA[$description]]></description> // short description of movie
         <url>$URL</url> // URL to the moviefile (FLV)
         <thumb>$thumb_url</thumb> // URL to thumbnail
      </item>

I've created a short PHP-script which allows me to enter this details through a form. All items is wrapped with <movie> and </movie>, and using the fgets()-function with a "while", the script is searching for the first <movie>-line and place the new entery right below it.

The source code is to be found here: http://norskwebforum.no/pastebin/10961 (text in norwegian, but I think you'll understand the point).

Now, I really want to add the functionality to edit and delete posts, but I don't know how to do this. Maybe I can generate the XML with a database, but I started with PHP to weeks ago, so I'm still pretty n00b at this.

So any help would've been much appriciated!

Either you can create the xml with the database or I would suggest you create a feed or master xml with the root node as movie as you mentioned and give specific ids for the items which you can use for identifying the posts.

Use xquery and Xpath to make changes to the xml file.

Hope this helps ..
