System.Xml.XmlDocument，缓存外部依赖项DTD的最佳方法是什么？ [英] System.Xml.XmlDocument, what's the best way to cache an external dependency DTD?

问题描述

我正在将有效的XHTML加载到XmlDocument中，但是加载需要2秒钟。我发现，如果放下DTD，它是即时的，但随后我必须替换& nbsp;到&＃160;等。已声明的HTML实体数量很多，因此我觉得应该加载DTD。那么，以最少的人工来预加载DTD的最简单方法是什么？也许我可以说是将DTD作为资源文件放入程序集中并注入..？有建议吗？

I'm loading valid XHTML into an XmlDocument, but it takes 2 seconds to load. I've found that if I drop the DTD, it's instant, but then I have to replace   to  , etc. The number of declared HTML entities is large, so I feel the DTD should be loaded. So what is the easiest way to pre-load the DTD with minimal manual labor? Perhaps if I could, say, put the DTD into the assembly as a resource file and inject it in..? Any suggestions?

推荐答案

我在这里找到了一种技术，方法是实现抽象类XmlResolver并将其设置为XmlDocument的XmlResolver属性。抽象类实现返回所请求URL的MemoryStream对象，该对象包含DTD或通常通过HTTP加载的其他任何资源。

I found a technique here, by implementing the abstract class XmlResolver and setting it to the XmlDocument's XmlResolver property. The abstract class implementation returns a MemoryStream object for the URL being requested, which contains the DTD or whatever other resource would normally be loaded over HTTP.
