Firefox  supports the W3C standards properties of attributes, childNodes, firstChild, lastChild, nextSibling, nodeName, nodeType, nodeValue, ownerDocument, parentNode, and previousSibling. So first  you need to retrieve the root element of the document by using the documentElement property,

var foxRoot = foxoXmlDom.documentElement;

 An example about how to return content of the node

function getText(foxNode) {
    var sText = "";
    for (var i = 0; i < foxNode.childNodes.length; i++) {
        if (foxNode.childNodes[i].hasChildNodes()) {
            sText += getText(foxNode.childNodes[i]);
        } else {
            sText += foxNode.childNodes[i].nodeValue;
        }
    }
    return sText;
}

Using XMLSerializer to  serialize XML

function serializeXml(foxNode) {
    var oSerializer = new XMLSerializer();
    return oSerializer.serializeToString(foxNode);
}
