 * @param {object} oElm The object you want to search, could be a whole document or something more specific.
 * @param {string} strTagName The string containing the name of the tag name i.e. "a", "div", "span" what ever the class name is attached to.
 * If no tag is given it will search all elements.
 * @param {string} strClassName The string containing the class name you're searching for
