It's not safe to look at the HTML5 language definition and assume that the same would work for the HTML4.01 documents, since the latter is a SGML-derived language and the former is a whole new separate language with its own parsing rules. While the HTML form of HTML5 bears a close resemblance to SGML and XML, it is a separate language with its own parsing rules.[1] That being said, the current HTML recommendation also allows dots in the ID[2]. > The issue is how would $$('#mail.com') differentiate between ... > > <span id="mail" class="com"> > and > <span id="mail.com"> > > No matter how you fiddle with the selector, the "." gets in the way. > As for the selector problem, I'd expect $('google.com') to work just like document.gEBI and fetch the right element, but the $$ selector should, IMHO, behave similarly to the Selectors API[3], allowing you to escape the dot in the selector, if you want to match an ID like the one said above. > If possible, I would change my id's and classes to only use the _ > symbol as this symbol is of no importance in any of the languages > (well, except as a single character in SQL's LIKE syntax). > Agreed.
