attributes

I found this useful regex code here while looking to parse HTML tag attributes:

(\S+)=["']?((?:.(?!["']?\s+(?:\S+)=|[>"']))+.)["']?

It works great, but it's missing one key element that I need. Some attributes are event triggers that have inline Javascript code in them like this:

onclick="doSomething(this, 'foo', 'bar');return false;"

Or:

onclick='doSomething(this, "foo", "bar");return false;'

I can't figure out how to get the original expression to not count the quotes from the JS (single or double) while it's nested inside the set of quotes that contain the attribute's value.
