webservice返回的xml解析方法：

一般来说，调用webService通常需要几个步骤，在调用之前，首先需要下载Soap的jar包。

1、参数设置：上面说到的几个参数都要先设置，这主要依赖于要调用的web'Service的网址：

// 命名空间

String nameSpace = "http://WebXml.com.cn/";

// 调用的方法名称

String methodName = "getDetailInfoByTrainCode";

// EndPoint

String endPoint = "http//webservice.webxml.com.cn/WebServices/TrainTimeWebService.asmx";

// SOAP Action

String soapAction = "http//WebXml.com.cn/getDetailInfoByTrainCode";

2、指定命名空间与调用方法名

// 指定WebService的命名空间和调用的方法名

SoapObject rpc = new SoapObject(nameSpace, methodName);

3、设置参数：

// 设置需调用WebService接口需要传入的两个参数TrainCode、userId

rpc.addProperty("TrainCode", params[0]);

rpc.addProperty("UserID","");

4、生成调用WebService方法的SOAP请求信息

// 生成调用WebService方法的SOAP请求信息,并指定SOAP的版本

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12);

envelope.bodyOut = rpc;

5、调用WebService方法

try {

// 调用WebService

transport.call(soapAction, envelope);

} catch (Exception e) {

e.printStackTrace();

}

6、解析WebService中的DataSet数据

SoapObject soap1=(SoapObject)object.getProperty("getDetailInfoByTrainCodeResult");

SoapObject childs=(SoapObject)soap1.getProperty(1);

SoapObject soap2=(SoapObject)childs.getProperty(0);

///

for(int i=0;i<soap2.getPropertyCount();i++){

SoapObject soap3=(SoapObject)soap2.getProperty(i);

///

Info info=new Info();

info.setStation(soap3.getProperty(0).toString());

info.setArriveTime(soap3.getProperty(1).toString());

info.setStartTime(soap3.getProperty(2).toString());

info.setKm(soap3.getProperty(3).toString());

Raininfo.add(info);

//result=soap3.getProperty(3).toString();

}

数据格式如下：

string title = HttpUtility.UrlEncode(txtTitle.Text);
string content = HttpUtility.UrlEncode(content1.Value);

string postData = "title=" + title + "&content=" + content;
byte[] dataBytes = Encoding.UTF8.GetBytes(postData);

System.Diagnostics.Stopwatch sw = new System.Diagnostics.Stopwatch();
sw.Start();
string url = System.Configuration.ConfigurationManager.AppSettings["KeywordWebService"];
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = dataBytes.Length;
request.Method = "POST";

Stream postStream = request.GetRequestStream();
postStream.Write(dataBytes, 0, dataBytes.Length);
postStream.Close();

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

System.Xml.XmlDocument xml = new System.Xml.XmlDocument();

StreamReader receiveStream = new StreamReader(response.GetResponseStream());
string receiveString = receiveStream.ReadToEnd();
sw.Stop();

xml.LoadXml(receiveString);

System.Xml.XmlNodeList keywords = xml.SelectNodes("//Keyword");
string strkeywords = "";
foreach (System.Xml.XmlNode keyword in keywords)
{
System.Diagnostics.Debug.WriteLine(keyword.InnerText);
strkeywords = strkeywords + keyword.InnerText + " ";
}

this.txtSearch.Value = strkeywords.Trim();
