Flash + XML parse question

[pete_s]

I have put together a simple flash that parses some text from a very simple XML, and it works just fine. Here is how the XML looks like

<result>
        <header>text</header>
        <content>text text</content>
        <info>text text text</info>
        <link>http://www.google.com</link>               
</result>

Now I would like the flash to make a difference between 3 different <types> tags in the XML. Then parse it togheter, but depending on witch <type> you choose it becomes slightly different in the layout. This is how the XML looks like

<result>
        <type>layout1</type>
        <header>text</header>
        <content>text text</content>
        <info>text text text</info>
        <link>http://www.google.com</link>       
</result>
<result>
        <type>layout2</type>
        <header>text</header>
        <content>text text</content>
        <info>text text text</info>
        <price>100</price>
        <link>http://www.google.com</link>       
</result>
<result>
        <type>layout3</type>
        <header>text</header>
        <content>text text</content>
        <info>text text text</info>
        <price>100</price>
        <units>100</untis>
        <link>http://www.google.com</link>       
</result>

My actionscript that parses the "simple" XML looks like this right now

function processXMLData(success)
{
        if (success)
        {
                var rootNode=this.firstChild;

                var headerNode=findNode(rootNode, "header");
                header=getValue(headerNode);
                
                var contentNode=findNode(rootNode, "content");
                content=getValue(contentNode);
                
                var infoNode=findNode(rootNode, "info");
                info=getValue(infoNode);
                
                var linkNode=findNode(rootNode, "link");
                link=getValue(linkNode);
                
        }
        else
        {
                content="Not found";
        }
}

function getValue(node)
{
  if (node && node.firstChild)
          return node.firstChild.nodeValue;
  return "";
}

function findNode(node, nodeName)
{
        if (node.nodeName==nodeName)
                return node;
        for (var i=0; node.childNodes && i<node.childNodes.length; i++)
        {
                var foundNode=findNode(node.childNodes[i], nodeName);
                if (foundNode!=null)
                        return foundNode;
        }
        return null;
}

link_btn.onRelease = function() {
                getURL(link, "_blank");
};
        
var xmlData=new XML();
xmlData.ignoreWhite=true;
xmlData.onLoad=processXMLData;
xmlData.load("info.xml");
stop();

Dose anyone have any suggestions or tutorials on how to do the things i like to do?
