For this reason I think "match" is a fine name for the single-result case. The default of regexp matching (likely the most familiar other match operation) is to give a single result. If there is to be another name it should be matchFirst though, not matchOne, to be clear that it's returning the first match not just some arbitrarily chose one. >> I am with Jonas on this - I don't think the name hurts or increases >> confusion and it does slightly decrease it.

Parsing the selector string is will likely be by far the least expensive part of the match operation. Regards, Maciej
