如何在xml中执行枚举

我有许多请求类型 – 它们确实是枚举.

但在我的代码中,这些请求类型是一个枚举：

enum RequestType {
  RequestRegister,
  RequestUnregister,
  etc
};

我目前对wsdl文件的尝试如下.但它使用字符串类型.在我的服务器中,我需要从xml中提取枚举/ int.对字符串进行查找似乎是糟糕的设计.

那么我如何形成我的wsdl文件,以便请求类型是枚举？

附加说明.

我被“强制”使用xml,因为客户端只能发送xml消息(无法控制).但是我组成了客户端使用的xml.我控制/写入的服务器是用C语言编写的,我使用libxml来提取xml文件的“部分”.理想情况下,该项目将是int或enum.因为我想这样做：

//从xml中提取项目 – 进入枚举或int
   RequestType rqtype = getRequestType();

switch(rqtype) {
 case RequestMakeCall:
  //do whatever

在上面的例子中,RequestType是一个枚举.提取字符串值然后必须查找相关的枚举值是没有效率的.

我看到枚举的所有例子似乎都使用字符串,这看起来很奇怪.

您可以创建自己的类型：
