递归java方法与xml解析

嗨，我有一个Java递归方法用来解析我的XML。我想为特定级别的XML中的元素设置名称空间。尝试设置计数器，但不起作用。有人能帮我吗

Xml文件：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>
      <LoginResponse>
         <Response>
            <ResponseCode>0</ResponseCode>
            <ResponseDescription>Request processed successfully</ResponseDescription>
         </Response>
         <SessionKey>12345a</SessionKey>
         <Service>false</Service>
      </LoginResponse>
   </soapenv:Body>
</soapenv:Envelope>

你的DOM需要被修改

    int level = 0;
    public void invokeBusinessLogic(Response response) throws Exception
    {   
        Iterator i = response.getFirstElement().getChildElements();//response.getFirstElement() is LoginResponse from the xml
        correctNamespace(i);
    }

    private void correctNamespace(Iterator i) {
        level++;

        while (i.hasNext()) {
            OMElement element = (OMElement) i.next();
            Iterator ii = element.getChildElements();
            element.setNamespace(null);
            if (level == 2)
            {
                element1.declareNamespace(URI, XMLNS);
            }
            correctNamespace(ii);
        }
    }   
}
