How to break/exit from a each() function in JQuery?

I have some code:

$(xml).find("strengths").each(function() {
   //Code
   //How can i escape from this block based on a condition.
});

How can i escape from the "each" code block based on a condition?

Update:

What if we have something like this:

$(xml).find("strengths").each(function() {
   $(this).each(function() {
       //I want to break out from both each loops at the same time.
   });
});

Is it possible to break out from both "each" functions from the inner "each" function?

If you want to continue instead of break out

return true;
