这就是我要解析的内容,
<?xmlversion="1.0"encoding="UTF-8"standalone="no"?>
<newPlayerConnectionrequest>
<participantType>1</participantType>
</newPlayerConnectionrequest>
创建消息的客户端代码:
Element rootElement = document.createElement(MyServer.NEW_PLAYER_CONNECTION_REQUEST);
Element participantTypeElement = document.createElement(MyServer.PARTICIPANT_TYPE);
Text textParticipantType = document.createTextNode(participantType);
participantTypeElement.appendChild(textParticipantType);
rootElement.appendChild(participantTypeElement);
document.appendChild(rootElement);
StringWriter sw = new StringWriter();
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer;
try {
transformer = tFactory.newTransformer();
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(sw);
transformer.transform(source, result);
} catch (TransformerConfigurationException e) {
e.printStackTrace();
}
catch (TransformerException t) {
t.printStackTrace();
}
try {
conn.setRequestMethod("POST");
} catch (ProtocolException e) {
e.printStackTrace();
}
conn.setRequestProperty("Content-Type", "text/xml");
//conn.setRequestProperty("Content-Length", "" + 8);
conn.setRequestProperty("Content-Language", "en-US");
conn.setDoInput(true);
conn.setDoOutput(true
我收到以下错误:

编辑我要解析的字符串:
答案 0 :(得分:8)
此行错误
<?xmlversion="1.0"encoding="UTF-8"standalone="no"?>
应该阅读
<?xml version="1.0"encoding="UTF-8"standalone="no"?>
请注意“xml”和“version”之间的空格
