I have a string that looks like this:

var str = "Hello world, &nbsp;hello &gt;world, hello world!";

... and I'd like to replace all the hellos with e.g. bye and world with earth, except the words that start with &nbsp or &gt. Those should be ignored. So the result should be:

bye earth, &nbsp;hello &gt;world, bye earth!

Tried to this with

str.replace(/(?!\&nbsp;)hello/gi,'bye'));

But it doesn't work.
