seems like there's a more efficient way of doing this..

getEl = function (selector) {
	if (document.querySelectorAll) {
		return document.querySelectorAll(selector);
	} else {
		if (selector.indexOf("#") > -1) {
			return document.getElementById(selector);
		} else {
			var sParts = selector.split("."),
				tags = document.getElementsByTagName(sParts[0]),
				matches = [];
			for (var i=0, l=tags.length; i<l; i++) {
				var classes = tags[i].className.replace(" ","|") + "|";
				if (classes.indexOf(sParts[1]+"|") > -1)
					matches.push(tags[i]);
			}
			return matches;
		}
	}
};
