Maybe this would help you :)

Thank you,
Mandy.

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
    "TEXT_NODE",                    // 3
    "CDATA_SECTION_NODE",           // 4
    "ENTITY_REFERENCE_NODE",        // 5
    "ENTITY_NODE",                  // 6
    "PROCESSING_INSTRUCTION_NODE",  // 7
    "COMMENT_NODE",                 // 8
    "DOCUMENT_NODE",                // 9
    "DOCUMENT_TYPE_NODE",           // 10
    "DOCUMENT_FRAGMENT_NODE",       // 11
    "NOTATION_NODE"                 // 12
];
