xml - Grails 错误 : invalid XML character (Unicode: 0x5c)

Question

我对这个问题做了一些研究，但似乎所有其他答案都包括更改向您发送响应的方式。我正在调用第三方 Web 服务，该服务返回一个 xml 字符串。当我在本地 Win7 机器上执行此操作时效果很好。但是当我将其发送到我们的服务器 Win Server 2003 时，我收到此错误返回:

Error 500: Executing action [vinlookup] of controller [AutoVehicleController] caused   exception: null

Answer 1

消息非常明确:

An invalid XML character (Unicode: 0x5c) was found in the public identifier.

“公共(public)标识符”是出现在 DOCTYPE 声明中关键字 PUBLIC 之后的字符串。公共(public)标识符中可以出现哪些字符是有规则的，并且不允许出现反斜杠。

你有一个选择。说服生成此标识符的人改正他们的方式，或者编写某种脚本来修复收到的错误 XML。不太可能有人关心公共(public)标识符的值是什么，因此您可以删除反斜杠而不造成任何损害。
