推荐答案

第一个也是最好的选择，如果您可以依靠HTML代码是格式良好的XML的事实，那么.NET可以很好地支持它.选择一种不同的方式:

First and best option is if you can rely upon the fact that an HTML code is well-formed XML which is well supported by .NET. Choose one different ways:

1. 使用System.Xml.XmlDocument类.它实现了DOM接口；如果文档太大，则这种方法最简单，也足够好.
   请参见
2. 使用类System.Xml.XmlTextReader; library/system.xml.xmldocument.aspx"target =" _ blank"title =" New Window> ^ ].
3. 使用类System.Xml.XmlTextReader;这是最快的读取方法，尤其是您需要跳过一些数据.
   请参见 http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.aspx [ http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx [http://msdn.microsoft.com/en-us/library/bb387063.aspx [

1. Use System.Xml.XmlDocument class. It implements DOM interface; this way is the easiest and good enough if the size if the document is not too big.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx[^].
2. Use the class System.Xml.XmlTextReader; this is the fastest way of reading, especially is you need to skip some data.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.aspx[^].
3. Use the class System.Xml.Linq.XDocument; this is the most adequate way similar to that of XmlDocument, supporting LINQ to XML Programming.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx[^], http://msdn.microsoft.com/en-us/library/bb387063.aspx[^].

如果不是这种情况，很不幸很有可能，您将需要一些HTML解析器来处理格式不正确的XML代码.试试这个: http://www.majestic12.co.uk/projects/html_parser.php [ ^ ].

If this is not the case, which is unfortunately very likely, you will need some HTML parser which can deal with the code which is not well-formed as XML. Try this one: http://www.majestic12.co.uk/projects/html_parser.php[^].
