This is a short function for Mootools decoding a string containing html entities to text.
function htmlspecialchars_decode(text)
{
var stub_object = new Element('span',{ 'html':text });
var ret_val = stub_object.get('text');
delete stub_object;
return ret_val;
}
Remember that you usually have no use for that function, because every element of mootools has a .get('text') function, which does the same.
