与DTD验证 - 连接强行关闭 [英] Validating with DTD - connection forcibly closed

问题描述

我验证与DTD这是不是我的机器上的文件中的文件，它存储在互联网上。

I'm validating a document with the DTD in the document which is not on my machine, it is stored on the internet.

我目前正在以下例外

System.Xml.XmlException: An error has occurred while opening external DTD 'http://xml.cxml.org/schemas/cXML/1.2.020/cXML.dtd': Unable to connect to the remote server --->

我知道该文件是可访问的，因为我可以浏览到它。但是，为什么不能.NET访问它？
在此先感谢

I know the file is accessible as I can browse to it. But why cannot .NET access it?! Thanks in advance.

推荐答案

我得到了以下情况例外，当我浏览[的 http://xml.cxml.org/schemas/cXML/1.2.020/cXML.dtd ] DTD文件

I got following exception when i browse the [http://xml.cxml.org/schemas/cXML/1.2.020/cXML.dtd ] dtd file.

XML解析错误：语法错误
地点：的 http://xml.cxml.org/schemas/cXML/1.2.020/cXML.dtd
线15号，第1列：

XML Parsing Error: syntax error Location: http://xml.cxml.org/schemas/cXML/1.2.020/cXML.dtd Line Number 15, Column 1:

只要下载DTD文件，并尝试在本地访问DTD。你可以缩小你的问题。

Just download the dtd file and try to access the dtd locally. You can narrow down your problem.
