This example shows how to use cross-browser DOM without the use of a javascript library like Sarissa. The code works on Opera 9, IE6/7/8, Firefox 1/2/3, Safari 1.2, Chrome 1.0.

If all goes well, the three paragraphs below should change after clicking the button:

para item_0

para item_1

para item_2

Use the following code:

function loadXML(file){
    try //Firefox, Mozilla, Opera, IE7/8 etc.
    {
        var req = new XMLHttpRequest();
        req.open("GET", file, false);
        req.send(null);
        return req.responseXML;
    } 
    catch (e) {
        try //Internet Explorer IE4/5/6
        {
            var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
            xmlDoc.async = false;
            xmlDoc.load(file);
            return xmlDoc;
        } 
        catch (e) {
            alert(e.message);
            return null;
        }
        
    }
}
