var xmlDoc = $.parseXML( xml );
var $xml = $( xmlDoc );

尝试这个

    var xml =$('<XMLDocument />')
    xml.append($('<TaxPayer/>')
               .append($('<PersonalInformation/>')
                       .append($('<FirstName/>').text('aashu')))); 
var xmlDoc = $.parseXML( xml );
var $xml = $( xmlDoc );
alert(xml.html());
xml.find('TaxPayer').find('FirstName').text('shri');
alert(xml.html());
