How does one get div content line-by-line with Javascript?
===

I need to process the content of a `<div>` line-by-line. A _shortened_ piece of it looks like this:

    <div id='aoeu'>
        Ammonium NH%4^+
        Copper(I) Cu^+
        Gold(I) Au^+
        Rubidium Rb^+
        Acetone CH%3COCH%3
        Glycerin C%3H%5(OH)%3
    </div>

I need to work with each line individually with Javascript.
