Dashboard Widget + XML?

[Fahrvergnuugen]

I want to write a dashboard widget that displays the last 5 posts of a web forum that I run. I've written a PHP script that runs on the server and queries the database for the information then spits out the result as XML.

Now I'm lost. I have no idea how to get my widget to load & parse the XML file that the server is generating. I have written plenty of parsers in PHP & Actionscript but never in JavaScript. I don't even know where to begin...

Unfortunately the Apple Developer page for dashboard doesn't have ANYTHING regarding XML parsing.

From what I understand the widget JavaScript is different than normal web JavaScript but in Web standard JavaScript you can do a obj.getElementsByTagName(sName) which will return an array of tag objects.

thanks, that looks like it should do the trick.
To get started though, how would you load the XML into an object?

You could try using XMLHttpRequest

var xmlhttp = new XMLHttpRequest();
xmlhttp.open("GET", "test.txt",true);
 xmlhttp.onreadystatechange=function() {
  if (xmlhttp.readyState==4) {
   alert(xmlhttp.responseText)
  }
 }
 xmlhttp.send(null)

I got the example from here: http://jibbering.com/2002/4/httprequest.html
