用socket发送xml文档，把生成的xml文档转化成字符流输出

Socket c = new Socket(host,port)
PrintWriter pw = new PrintWriter(new OutuputStreamWriter(c.getOutputStream()),true);

File f = new File(xml);
BufferedReader br = new BufferedReader(new FileReader(f));
String line;
while((line = br.readLine()) != null)
pw.println(line);

pw.close();
br.close();
