on line 111 the nodeNames need changing from upper case to lower case. from if (e.nodeName == 'UL' || e.nodeName == 'OL') { to if (e.nodeName == 'ul' || e.nodeName == 'ol') {
simply because all tags should be lower case, if using the xhtml+xml header you will get an error about clip[0] being undefined, the fix above fixes this. using version 0.2.3 be great if we could see this fixed, if not this is how to fix it for anyone else.
