Try this, if all you want to do is go through a page finding any element with the classname quote_content and return its HTML content:
$$('.quote_content').each(function(elm){
// do whatever you like with elm.innerHTML
alert( elm.innerHTML );
// note that any whitespace, as in your example
// will be preserved. You may prefer this instead:
var child = elm.down();
alert( child.outerHTML );
// this only works if you know there is only one
// child element, though
});
