Console hijacking the W3C Microdata draft document http://www.w3.org/html/wg/drafts/microdata/master/ to provide parser results inline with the draft examples. Currently works by passing pre contents to a local http server that runs the data through the specified parser and returns the results as serialized JSON.

var halfWidth = { width: '45%', float: 'left', background: '#ccc', margin: '10px 0', padding: '5px', 'border-right': 'solid 1px #aaa' };

$('pre').css(halfWidth).each(function () {
    var $pre = $(this);

    $.ajax({
        url: 'http://localhost:50231/api/hello',
        data: { markup: $pre.text() , uri: window.location.href, impl: ''},
        dataType: 'json',
        success: function(result) {    
            $pre.after(
                $('<pre>').text(result).addClass('jlewin').css(halfWidth).after($('<hr>').css({clear: 'both'}))
            );
        }
    });
