jQuery.fn.extend({
    getPath: function (path) { /*The first time this function is called, path won't be defined*/
        if (typeof path == 'undefined') path = ''; /*Add the element name*/
        var cur = this.get(0).nodeName.toLowerCase();
        var id = this.attr('id'); /*Add the #id if there is one*/
        if (typeof id != 'undefined') { /*escape goat*/

        var html = this.html();
        if (html.search('
