ios 4 和 ios 5 ipad 之间的 XML 解析差异
我真的很难理解一些事情。在我得到的项目中，解析了一些来自soap Web 服务的XML。这在 iOS 4 中工作得很好。当我尝试在 iOS 5 模拟器或 iOS 5 设备中运行代码时，XML 无法正确解析。它给出了 NSXMLParser 域错误代码 4。
当我查看 XML 时，即使在工作操作系统中，来自 Web 服务的数据也有 < 和 > 而不是所有 XML 标记。但这似乎在 iOS 4 中仍然有效。在 iOS 5 中，我收到上面提到的错误和 错误请求 消息。我也无法按原样获取返回的 XML，到目前为止我只能在 NSData 中看到。
我想知道这是否是由于iOS版本的变化或其他原因造成的。我希望我说清楚了。也许即使有了这些信息，也会有一些答案。
提前致谢， 艾伦
I am having a real hard time understanding something. In the project I've been given, some XML coming from a soap web service is parsed. This works just fine in iOS 4. When I tried to run the code in iOS 5 simulators or a device with iOS 5, the XML is not parsed correctly. It gives NSXMLParser domain error code 4.
When I looked at the XML, even in the working OS, the data coming from the webservice has < and > instead of all the XML tags. But that seems to still work in iOS 4. In iOS 5, i get the error mentioned above and a Bad Request message. I also couldnt manage to get the returning XML as it is, so far I was only able to see in NSData.
I'd like to know if this may be caused by any change in iOS versions, or anything else. I hope I made myself clear. Maybe even with this info, there'll be some answers.
Thanks in advance,
Eren

NSXMLParserError域错误 4 是NSXMLParserEmptyDocumentError。听起来问题在于从 Web 服务检索原始 XML 文档以及 iOS 4 和 iOS 5 之间的一些变化。这应该会让您走上正确的轨道。如果可以的话，发布一些代码，我们可以提供更多信息。The
NSXMLParserErrordomain error 4 isNSXMLParserEmptyDocumentError. It sounds like the problem lies with the retrieval of the original XML document from the web service and some change between iOS 4 and iOS 5. This should get you started on the right track. Post some code when you can and we can give more information.
