我正在使用 Metro 调用 SOAP Web 服务。我从我无法控制的服务器接收到 SOAP 响应，其正文中包含无效字符引用。我想在 Metro 解组 XML 并向我的客户端抛出异常之前修复该 XML。这可能吗？
我尝试添加 aLogicalHandler和 a ，但是当我尝试获取有效负载（分别SOAPHandler失败）时，它们都会抛出相同的解组异常。当响应没有无效的 XML 时，处理程序工作正常，让我可以访问消息。LogicalMessage.getPayload()SOAPMessageContext.getMessage()
异常如下所示：
com.sun.xml.internal.ws.encoding.soap.DeserializationException: Failed to read a response: javax.xml.bind.UnmarshalException
- with linked exception:

有没有办法可以获取原始有效负载，修复它并替换回来并继续？
