手把手教你SOAP访问webservice并DOM解析返回的XML数据（转）

new Thread(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
PostMethod postMethod = new PostMethod(
"服务地址，即上面request中的host+端口号+post");
// 然后把Soap请求数据添加到PostMethod中
byte[] b = null;
try {
b = soapRequestData.getBytes("utf-8");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
InputStream is = new ByteArrayInputStream(b, , b.length);
RequestEntity re = new InputStreamRequestEntity(is,
b.length, "application/soap+xml; charset=utf-8");
postMethod.setRequestEntity(re);
// 最后生成一个HttpClient对象，并发出postMethod请求
HttpClient httpClient = new HttpClient();
try {
int statusCode = httpClient.executeMethod(postMethod);
if (statusCode == ) {
Log.d("soapRequestData", "调用成功！");
StringBuffer buffer = new StringBuffer();
// 解析器 工厂类
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
//返回流式数据
InputStream soapResponseData = postMethod
.getResponseBodyAsStream();
Document dm = db.parse(soapResponseData);
// element和node是同一概念
// 不同的是element提供更多方法
if (dm.getElementsByTagName("Root").item()
.getFirstChild() != null) {
// j是Root即根节点下面节点个数
for (int j = ; j < dm .getElementsByTagName("Root").item()
.getChildNodes().getLength(); j++) {
String result3 = dm.getElementsByTagName("Root") .item().getChildNodes().item(j).getTextContent();
buffer.append(result3);
}
}
} else {
Log.d("soapRequestData", "调用失败！错误码：" + statusCode);
}
} catch (HttpException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ParserConfigurationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}).start();
