Java 解析 soap xml 报文

怎么获取 PushSMSYMResult 中的内容？？

 <?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<PushSMSYMResponse xmlns="http://tempuri.org/">
<PushSMSYMResult>
Yes:短信插入成功
</PushSMSYMResult>
</PushSMSYMResponse>
</soap:Body>
</soap:Envelope>

Document document = DocumentHelper.parseText(results);

Element root = document.getRootElement();
System.out.println(root.getStringValue());
