Updated Code

//Sometimes, setting an element attribute (e.g., title) with javascript automatically escapes all amphersands in the
// string, apparently to be "helpful". It also does this when creating a text node with document.createTextNode.
//This function gets around this by setting innerHTML on a temporary element and returning the text node's value.
function literalText(str)
{
	var tmp = document.createElement("div");
	tmp.innerHTML = str;
	return (tmp.firstChild ? tmp.firstChild.nodeValue : "");
}
