包含无效XML字符的EWS响应 [英] EWS response containing invalid XML characters

问题描述

您好，

我曾经多次体验到EWS的响应会返回XML中非法的符号字符（至少根据Apache Axis2以及我/我们如何取消和XML规范）。它似乎与unicode控制字符（范围x1 - x1F）有关。

这个问题的一部分可能与EWS返回xml版本1.0（根据XML）但可能（只是可能）有关返回的内容实际上是遵循XML 1.1规范（允许unicode控制字符） - 请附上示例（蓝色突出显示的XML版本 - 红色突出显示无效字符）。

有没有人遇到此问题？有没有人找到解决这个问题的方法？这是Exchange中的错误吗？

Hi there,

At several occasions I have experienced that the response from EWS returns contaons characters that are illegal within XML (at least according to Apache Axis2 and also how I/we undertsand the XML specs). It seems to be related to unicode control characters (range x1 - x1F).

Part of this problem may be related to the fact that EWS return xml version 1.0 (according to the XML) but maybe (just maybe) what is returned is in fact adhering to the XML 1.1 spec (which does allow unicode control characters) - please se attached example (XML version highlighted in blue - invalid character highlighted by red).

Has anyone experienced this problem? has anyone found a way around this? is this a bug in Exchange?

Regards
Mads

推荐答案

我目前有这个问题。我正在使用Exchange 2007 Web服务，从C＃代码调用。您是否找到了解决此问题的方法？
我认为Web服务API会暴露一些我可以启用某些编码的属性。

I currently have this problem.  I am using Exchange 2007 Web Services, calling from C# code.  Have you found a solution to this issue?
I thought the web service API would expose some property where I could enable some encoding.
