在将文件（xml）提交到服务器之后的C＃中，获得了具有一些边界标题的响应XML

Question

我得到了服务器响应，它有一些标题信息，所以一旦我们试图获取节点信息和其他东西，它会因为标题而抛出错误。 在这里，我分享了包含页眉和页脚的xml。 我不需要这个页眉和页脚部分。 在C＃.net中，我们删除它并读取xml元素。

public string PostXMLData(string destinationUrl, string requestXml)
    {
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl);
        string responseStr = string.Empty;
        try
        {
            byte[] bytes;
            bytes = System.Text.Encoding.ASCII.GetBytes(requestXml);
            request.ContentType = "text/xml; encoding='utf-8'";
            request.ContentLength = bytes.Length;
            request.Method = "POST";
            request.UseDefaultCredentials = false;
            request.PreAuthenticate = true;
            request.AllowAutoRedirect = false;

            request.Proxy = new WebProxy(ConfigurationManager.AppSettings["Proxy"], Convert.ToInt32(ConfigurationManager.AppSettings["Port"]));
            request.Headers.Add("Authorization", "Basic " +
                Convert.ToBase64String(Encoding.GetEncoding("utf-8").GetBytes(ConfigurationManager.AppSettings["uid"] + ":" + ConfigurationManager.AppSettings["pass"])));
            request.Credentials = new NetworkCredential(ConfigurationManager.AppSettings["uid"], ConfigurationManager.AppSettings["AtomPassword"]);

            Stream requestStream = request.GetRequestStream();
            requestStream.Write(bytes, 0, bytes.Length);
            requestStream.Close();

            HttpWebResponse response;
            response = (HttpWebResponse)request.GetResponse();

            if (response.StatusCode == HttpStatusCode.OK)
            {
                Stream responseStream = response.GetResponseStream();
                responseStr = new StreamReader(responseStream).ReadToEnd();

            }
            responseStr.Remove(0, 195);
        }
