XDocument.Parse失败，由于分辨率的错误，如何禁用

Question

分辨率我试图用XDocument.Parse(string)解析的http://feeds.feedburner.com/riabiz内容（因为它可以让在DB缓存）

然而，保持与下面的堆栈失败在尝试解析该XML中的某些URI时进行跟踪。

我不关心验证或任何XML废话，我只是想分析结构。如何在不使用此URI解析的情况下使用XDocument？

Answer 1

这里是我如何停止的XML解析：

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 { 
     } 
    } 
} 

请让我知道，如果这是正确的。

你可以简单地清除XmlResolver：

r.XmlResolver = null; 

的推荐方法创建XmlReader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，你也可以完全禁用DTD的处理（即URI来自哪里）：

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