ActionScript 3.0 code:

var XMLLoader:URLLoader;
var XMLPath:URLRequest;
var XMLDoc:XMLDocument = new XMLDocument();
XMLDoc.ignoreWhite = true;

XMLPath = new URLRequest("test.xml");
XMLLoader = new URLLoader(XMLPath);
// Call extractXMLFileData function if the XML file does load.
XMLLoader.addEventListener("complete", extractXMLFileData);
// Call errorXMLFileData function if the XML file didn't load.
XMLLoader.addEventListener("ioError", errorXMLFileData);

// This function parse the data from the XML file, if it is loaded.
function extractXMLFileData(event:Event):void
{
    var XMLData:XML = XML(XMLLoader.data);
    XMLDoc.parseXML(XMLData.toXMLString());
// Define the first node.
    var DataNode:XMLNode = XMLDoc.firstChild; 

// Read a node attribute.
    trace(DataNode.firstChild.attributes.font);
// Read a node value.
    trace(DataNode.firstChild.firstChild.nodeValue);
// Here we read the node value that contains the HTML text.
    trace(DataNode.childNodes[1].firstChild.nodeValue); 

// In the next "for" we read all the URL nodes.
    for (var currentNode = DataNode.childNodes[2].firstChild;
currentNode != null; currentNode=currentNode.nextSibling)
    {
// If the name of the node is "URL" then we read the value from it.
        if (currentNode.nodeName == "URL")
        {
            trace(currentNode.firstChild.nodeValue);
        }
    }
}

// This function takes action if the XML file didn't load.
function errorXMLFileData(event:Event):void
{
    trace("Error! The XML file didn't load!");
}
