I recently wrote something similar but not as complex, and feel very gratefull to see someone who knows more about Javascript than I demonstrate something similar. Lately I've been thinking I'm not writing enough code to learn how JavaScript really works without even considering cross-browser issues. I must write more code! I'm looking at too much code and not writing enough examples. Thanks again! I'm learning a lot! Thanks for being so kind and writing and publishing this code!

Lately I’ve been thinking I’m not writing enough code to learn how JavaScript really works without even considering cross-browser issues. I must write more code! I’m looking at too much code and not writing enough examples.

Thanks again!
I’m learning a lot!

A couple of notes: 1) The scripts doesn't take care of some attributes conversion (it only takes care of "class" -> "className" conversion but not, say, "for" -> "htmlFor") 2) When creating regexp, it's a good idea to escape meta characters, since trying to match something like "?" will throw SyntaxError. I would just treat strings as strings and allow regexp objects as values. Interesting snippet.

However, I disagree with Lachlan on using Sizzle directly; it may be appealing because it is used by several major libraries, but the VAST majority of developers would be better of using a library that implements Sizzle rather than using Sizzle itself.
