Hmm… that is a pretty cool class. I
was hoping more for something that you didn’t need to know what the tag
names were, it would just create a hierarchy that you could drill down into
easily, but if I get stuck, this is a good backup.

_javascript_ xml parser
Maybe this
would help you :)
p.s. I have not
written this. I got this from some site long time back.
XMLParser = Class.create();
Object.extend(XMLParser.prototype, {
initialize: function(xmlObj) {
this.xmlObj = xmlObj;
this.root = xmlObj.documentElement;
},
list: function(value) {
var result = this.root.getElementsByTagName(value);
return result;
},
get: function (node, value) {
if(typeof value != 'undefined')
node = node.getElementsByTagName(value).item(0);
return this.text(node);
},
toArray: function(value) {
var list = this.list(value);
var nodeValues = new Array();
for (var i = 0; i < list.length; i++) {
nodeValues.push(this.get(list[i]));
}
return nodeValues;
},
text: function (node) {
if (typeof node.textContent != 'undefined') {
return node.textContent;
}
else if (typeof node.innerText != 'undefined') {
return node.innerText;
}
else if (typeof node.text != 'undefined') {
return node.text;
}
else {
switch (node.nodeType) {
case 3:
case 4:
return node.nodeValue;
break;
case 1:
case 11:
var innerText = '';
for (var i = 0; i < node.childNodes.length; i++)
{
innerText += text(node.childNodes[i]);
}
return innerText;
break;
default:
return '';
}
}
}
});
XMLParser.nodeType = [
"",
"ELEMENT_NODE", // 1
"ATTRIBUTE_NODE", // 2
