Without context you can't get the cascading or "winning" values for css attributes. You could create a whole pseudo document to get this, but it is needlessly complex. You say you would want .error to not get matched by div.error, but in a real document the order of the styles and the weight of them (id's over classes, !important rules, etc) dictate the final style attributes.
