Question

我正在尝试使用XDocument.Parse(string)解析http://feeds.feedburner.com/riabiz的内容（因为它会缓存在数据库中。）

但是，当它尝试解析该XML中的某些URI时，它仍然无法使用下面的堆栈跟踪。

我不关心验证或任何XML废话，我只想解析结构。如何在没有此URI解析的情况下使用XDocument？

Answer 1

以下是我停止XML解决方案的方法：

var r = new System.Xml.XmlTextReader(new StringReader(xml));
r.XmlResolver = new Resolver();

var doc = XDocument.Load(r);

class Resolver : System.Xml.XmlResolver {
    public override Uri ResolveUri (Uri baseUri, string relativeUri)
    {
        return baseUri;
    }
    public override object GetEntity (Uri absoluteUri, string role, Type type)
    {
        return null;
    }       
    public override ICredentials Credentials {
        set {
        }
    }
}

如果这是正确的，请告诉我。

您只需清除XmlResolver：

即可

r.XmlResolver = null;

创建XmlReader的推荐方法是使用通用XmlReader.Create()，在这种情况下：

XmlReaderSettings settings = new XmlReaderSettings();
settings.XmlResolver = null;
XmlReader r = XmlReader.Create(new StringReader(xml), settings);

使用.NET 4.0或更高版本，您还可以完全禁用DTD的处理（URI来自的位置）：

XmlReaderSettings settings = new XmlReaderSettings();
settings.DtdProcessing = DtdProcessing.Ignore;
XmlReader r = XmlReader.Create(new StringReader(xml), settings);
