如何使用Apache HttpClient发送XML POST请求？

Question

我想按照以下格式进行HTTP POST，

<?xml version="1.0" encoding="UTF-8" ?>
<authRequest>
 <username>someusernamehere</username>
 <password>somepasswordhere</password>
</authRequest>

我通常使用以下机制进行任何基于登录的POST，

HttpParams params = new BasicHttpParams();
        params.setParameter(
                "http.useragent",
                "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.2) Gecko/20100115 Firefox/3.6");
        DefaultHttpClient httpclient = new DefaultHttpClient(params);

        HttpPost httppost = new HttpPost("http://mysite.com/login");
        List<NameValuePair> formparams = new ArrayList<NameValuePair>();
        formparams.add(new BasicNameValuePair("username", "stackoverflow"));
        formparams.add(new BasicNameValuePair("password", "12345"));
        UrlEncodedFormEntity entity = new UrlEncodedFormEntity(formparams, "UTF-8");
        httppost.setEntity(entity);
        HttpResponse httpresponse = httpclient.execute(httppost);

但是通过这种方式，POST数据看起来像，

username=stackoverflow&password=12345

如何根据我上面提到的指定XML格式格式化此请求？

提前致谢。

使用其他类型的HttpEntity。 the documentation顶部列出了许多实现。
