XML filter is applied to non-XML value

XML filter is applied to non-XML value

Hello,

I'm using jCarousel, to set up carousel, and display requested items with AJAX.

Here are my to trouble-maker functions :

function mycarousel_itemLoadCallback(carousel, state)
{
    // Check if the requested items already exist
    if (carousel.has(carousel.first, carousel.last)) {
        return;
    }
   
    $.get(
        'dynamic_ajax_php.php',
        {
            first: carousel.first,
            last: carousel.last
        },
        function(xml) {
            mycarousel_itemAddCallback(carousel, carousel.first, carousel.last, xml);
        }, 'html'
    );
};

function mycarousel_itemAddCallback(carousel, first, last, xml) {
   // Set the size of the carousel
    carousel.size(parseInt(jQuery('total', xml).text()));
   
    jQuery('product', xml).each(function(i) {
      var product_id = jQuery.('product_id', xml).text();
      
      carousel.add(first + i, mycarousel_getItemHTML(jQuery(this).text()));
    });
};


This code returns a "XML filter is applied to non-XML value" error in Firebug.

If I switch from

$.get(
        'dynamic_ajax_php.php',
        {
            first: carousel.first,
            last: carousel.last
        },
        function(xml) {
            mycarousel_itemAddCallback(carousel, carousel.first, carousel.last, xml);
        }, 'html'
    );


to

$.get(
        'dynamic_ajax_php.php',
        {
            first: carousel.first,
            last: carousel.last
        },
        function(xml) {
            mycarousel_itemAddCallback(carousel, carousel.first, carousel.last, xml);
        }, 'xml'
    );

then mycarousel_itemAddCallback is not even called.

Here is the string returned by dynamic_ajax_php.php :

<data> <total>9</total> <product> <product_id>2</product_id> <product_title>T-shirt Beige mootools</product_title> </product> <product> <product_id>3</product_id> <product_title>T-shirt Blanc mootools</product_title> </product> <product> <product_id>4</product_id> <product_title>T-shirt Vert mootools</product_title> </product> <product> <product_id>5</product_id> <product_title>T-shirt Bleu mootools</product_title> </product></data>


Any idea what's going wrong ?
