使用jQueryAjax提交表单并获取xml响应

我有一个表单可以跨域提交，但页面将返回一些XML，如下所示：

<response>
<result>12</result>
<message>Invalid parameter.</message>
<error><code>0</code>
<desc>Parameter[first_name] value is empty</desc>
</error>
</response>

我需要使用什么JQuery Ajax提交表单格式才能提交表单并获得结果，例如我需要标签中的内容。

通常这是我使用的Ajax表单提交代码

          $.ajax({
        dataType: "json",
        method: "POST",
        url: 'url',
        data: $('#your_form').serialize(),
        success: function (data) {
            //whatever
        }
    });

在任何情况下，如果您想要发出跨域请求，您必须更改控制器以允许它

          public static final String ACCESS_CONTROL_ALLOW_ORIGIN = "Access-Control-Allow-Origin";
public static final String ACCESS_CONTROL_ALLOW_CREDENTIALS = "Access-Control-Allow-Credentials";
public static final String ACCESS_CONTROL_ALLOW_HEADERS = "Access-Control-Allow-Headers";
public static final String ACCESS_CONTROL_REQUEST_HEADERS = "Access-Control-Request-Headers";
public static final String ACCESS_CONTROL_ALLOW_METHODS = "Access-Control-Allow-Methods";
public static final String ACCESS_CONTROL_REQUEST_METHOD = "Access-Control-Request-Method";
public static final String ACCESS_CONTROL_ALLOW_METHODS_VALUE = "GET, POST, PUT, OPTIONS";



       response.addHeader(ACCESS_CONTROL_ALLOW_ORIGIN, request.getHeader(ORIGIN));
       response.addHeader(ACCESS_CONTROL_ALLOW_CREDENTIALS, ALLOW_CREDENTIALS);

你能添加你的代码吗？
