gsoap+onvif xml解析不了

初学onvif协议，环境是在linux下，使用gsoap生成了代码框架，经过修修改改，终于能编译通过了，但使用GetCapabilities，想获取海康IPC的Media（或其它设备能力）地址时，没有任何报错，但Response->Capabilities->Media == NULL,代码如下。

}

代码运行的效果就是soap->error == 0，但Response->Capabilities->Media == NULL，所以我追看了gsoap的DEBUG日志，发现发送和接收都没有问题，返回的HTTP协议内容完整，XML中也可以看到我需要的值。但问题是无法正确解析收到的信息，具体报错如下：

Tags 'tt:Media' and 'SOAP-ENV:' match but namespaces differ
IGNORING element 'tt:Media'

也就是说应该是因为没有解析正确，所以导致了Response->Capabilities->Media没有被填充，关键log如下：

Tags 'tt:Media' and 'SOAP-ENV:' match but namespaces differ
IGNORING element 'tt:Media'
标记“tt:Media”和“SOAP-ENV:”匹配，但命名空间不同
IGNORING元素“tt:Media”
两种可能
1.你调用了一个自定义或是第三方的类,所以要引用第三方的类的空间或自己的
2.你想调用的是System.Media,那么,你不可以这样调用,因为Media是命名空间,不是类,这个命名空间下应该有三个类,明白没?
System.Media.SoundPlayer sp = new System.Media.SoundPlayer();
