Hi, I changed the XML parser who have been write by Greg (Gregory Hill)
and changed some things.
It did not work in IE and Safari and opera.
I fixed some bugs. Now it works fine in IE, Safari, Firefox and Opera.
/* --------------------------------------- */
XMLParser = Class.create();
Object.extend(XMLParser.prototype,
{
initialize: function (XMLFile, options)
{
this.xmlFile = XMLFile;
this.options = options;
this.element = false;
this.XMLParsed = 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;
this.XMLParsed = this.asHash();
if(this.options.onComplete) {
this.options.onComplete(this.XMLParsed);
}
},
_nodeToHash: function (node)
{
Element.cleanWhitespace(node);
//
// remove comments, firefox fix
node = this._removeComments(node);
if ((node.attributes && node.attributes.length > 0) ||
(node.hasChildNodes() && (node.childNodes[0].nodeType == 1 ||
node.childNodes[0].nodeType == 7))) {
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 ||
node.childNodes[0].nodeType == 7)) {
$A(node.childNodes).each(function (node) {
this._subNodeToHash(localHash, node);
}.bindAsEventListener(this));
}
else if (node.hasChildNodes()) {
localHash['text'] = [this._nodeAsText(node)];
}
$H(localHash).each( function (pair) {
if (pair[1].length == 1 && typeof pair[1][0] == 'string') {
localHash[pair[0]] = pair[1][0];
}
});
return localHash;
} else {
return this._nodeAsText(node);
}
},
_removeComments: function(node)
{
for(var i=0; i < node.childNodes.length; i++) {
var nodeTmp = node.childNodes[i];
if(nodeTmp.nodeType == 8) {
Element.remove(nodeTmp);
}
}
return node;
},
_subNodeToHash: function (hash, node)
{
var key = node.tagName;
if (hash[key]) {
hash[key].push(this._nodeToHash(node));
} else {
hash[key] = [ this._nodeToHash(node) ];
}
},
_nodeAsText: function (node)
{
return node.textContent || node.innerText || node.text ||
node.childNodes[0].nodeValue || '';
}
}
);

/* How To use it */
/* --------------------------------------- */
<*cript>
function showBlog(xml)
{
$('outputField').innerHTML = '';
var total = xml.rss[0]['channel'][0]['item'].length;
for(var i=0; i < total; i++) {
$('outputField').innerHTML += '<a
href="'+xml.rss[0]['channel'][0]['item'][i]['link']+'"
target="_blank"><b>'+xml.rss[0]['channel'][0]['item'][i]['title']+'</b></a><br
/>';
$('outputField').innerHTML +=
xml.rss[0]['channel'][0]['item'][i]['description']+'<hr>';
}
}
</*cript>
<input type="button" name="b_rss" value="RSS 2" onClick="new
XMLParser('./myrss2.xml'),{onComplete:showBlog});" />
