onCloseTag is missing "attribute" parameter #57
Description
Compared to its onOpenTag counterpart, onCloseTag is missing the "attribute" parameter, and this is a very big issue(or flaw if you prefer) because attribute parameter is very essential to usefully scrape pages since they are only way to identify unique tags among a sea of them in the very same html file.
Having the informations about the attributes on the opening end but not the closing end adds a lot of unnecessary boilerplate to manually track which tags are already opened and their respective attributes.
