从控制器操作返回 RDF - ASP.NET MVC
我有一个控制器操作，它将 RDF 文档作为 XML 返回到浏览器。浏览器抱怨文档无法显示：
命名空间前缀不允许以保留字符串“xml”开头。处理资源时出错
我试图使用 MCVContrib 的 XMLResult 对象将文档写入响应流。如何才能让该文档在浏览器中正确显示？我必须写一个普通的字符串吗？
public ActionResult Content(string id, string version, string localization)
{
IDocumentRequest request = new ResourceRequest()
{
Id = id,
Localization = Localization.GetByName(localization),
Version = version
};
XmlDocument doc = _kbModel.GetContent(request);
return new XmlResult(doc);
}
I have a controller action that returns a RDF document as XML to the browser. The browser complains that the document cannot be displayed:
The namespace prefix is not allowed to start with the reserved string "xml". Error processing resource
I was attempting to use MCVContrib's XMLResult object to write the document out to the response stream. How can I have this document displayed correctly to the browser? Do I have to resort to writing a plain string?
public ActionResult Content(string id, string version, string localization)
{
IDocumentRequest request = new ResourceRequest()
{
Id = id,
Localization = Localization.GetByName(localization),
Version = version
};
XmlDocument doc = _kbModel.GetContent(request);
return new XmlResult(doc);
}

RDF 有一个不同的 MIME 类型，只是 XML。 XMLResult 会将 MIME 类型设置为“application/xml”，而 RDF 需要的是“application/rdf+xml”。您需要设置此手册，或者您可以创建自己的 ActionResult 来设置它。
请参阅：http://www.w3.org/TR/ rdf-syntax-grammar/#section-MIME-Type
RDF has a different MIME type thank just XML. XMLResult will set the MIME type to "application/xml" and what is needed by RDF is "application/rdf+xml". You need to set this manual or you can create your own ActionResult that sets it.
SEE: http://www.w3.org/TR/rdf-syntax-grammar/#section-MIME-Type
您返回的文档的根目录中有一个
xml命名空间（如 'xmlns:xml="..."'）。或
您使用的是旧版
Microsoft XML (MSXML)解析器，版本等于Microsoft XML Core Services 4.0或更低版本。 更新到MSXML 的最新版本< /a>.原因：您在返回的 XML 文档的命名空间前缀（即
xml）中使用了一个/某些 Microsoft XML (MSXML) 关键字，例如，您有一个类似于 <返回的 xml 文档中的 code>xmlMyProject。请注意，
xml大小写并不重要，即XMLMyProject、XmlMyProject...You have an
xmlnamespace (as 'xmlns:xml="..."')at the root of your returned document.OR
You are using an old
Microsoft XML (MSXML)parser equal toMicrosoft XML Core Services version 4.0or lower. Update to the last version of MSXML.Reason: You are using one/some of Microsoft XML (MSXML) keywords in your namespace prefixes in the returned XML document, i.e
xml,For example you have a namespace like
xmlMyProjectin returned xml document. Note thatxmlcapitalization doesn't matter, i.e.XMLMyProject,XmlMyProject...
