Jquery validate if/else errorplacement and plus placement in div

I have a form where the placement for radiobuttons is different then for the other elements in the form.

I would like to keep this but also add the errors into a div. Is it possible to do this?

Right now i have this for the radiobutton placement

$('#newform').validate({
    onfocusout: function(element) { $(element).valid(); },
    errorPlacement: function(error, element) {
        if ( element.is(":radio") ) {
            error.prependTo( element.parent() );  
        }
        else { // This is the default behavior of the script  
            error.insertAfter( element );
        }  
    },
    rules{XXX},
    messages{}

And so on. How can I add the errormessages to a div without removing the current funcionality?

use the errorLabelContainer option :

$("#myform").validate({
   errorLabelContainer: "#messageBox",
   wrapper: "li"
})

Sorry i missunderstood your problem ....

try this :

$('#newform').validate({
        onfocusout: function(element) { $(element).valid(); },
        errorPlacement: function(error, element) {
            if ( element.is(":radio") ) {
                error.prependTo( element.parent() );  
            }
            else { // This is the default behavior of the script  
                error.insertAfter( element );
            }
            error.appendTo('#errordiv');
        },

This will keep your current functionallity but also append the message to the div with an id of 'errordiv'
