Hi Gregory
What you think about this
/* -------------------------------------- */
XMLDoc = Class.create();
Object.extend(XMLDoc.prototype,
{
initialize: function (XMLFile, options)
{
this.xmlFile = XMLFile;
this.options = options;
this.element = false;
this.getXml();
},
XMLHash: function ()
{
return this.XMLParsed;
},
asHash: function ()
{
if (! this._xmlHash) {
this._xmlHash = this._nodeToHash(this.element);
}
return this._xmlHash;
},
getXml: function ()
{
if(this.options.onLoading) {
this.options.onLoading();
}
new Ajax.Request(this.xmlFile, {method:'get', onComplete:
this.parseXML.bind(this)});
},
parseXML: function (req)
{
this.element = req.responseXML;
var XMLParsed = this.asHash();
if(this.options.onComplete) {
this.options.onComplete(XMLParsed);
}
},
_nodeToHash: function (node)
{
Element.cleanWhitespace(node);
if ((node.attributes && node.attributes.length > 0) ||
(node.hasChildNodes() && node.childNodes[0].nodeType == 1)) {
var localHash = {};
if (node.attributes && node.attributes.length >= 1) {
$A(node.attributes).each(function (attr) {
localHash[attr.nodeName] = [attr.nodeValue];
});
}
if (node.hasChildNodes() && node.childNodes[0].nodeType ==
1) {
$A(node.childNodes).each(function (node) {
this._subNodeToHash(localHash, node);
}.bindAsEventListener(this));
}
else if (node.hasChildNodes()) {

}
$H(localHash).each( function (pair) {

},
_nodeAsText: function (node)

/* -------------------------------------- */
Usage:
/* ************** */
function showRssLength(xml)
{
/* this is an example */
alert(xml.rss[0]['channel'][0]['item'].length);
}
new XMLDoc('rssFile.xml',{onComplete:showRssLength});
/* ************** */
