Once you've converted the data to XML, you can use XSLT to transform it to a simpler set of XML and one that is more suited to your purposes. From there you can use LINQ to XML to get the data you need out of the XML. The benefit to this approach is that it decouples the website from the data gathering so that when the website changes their format you can simply change the XSLT to match and nothing else has to be touched.

将数据转换为XML后,可以使用XSLT将其转换为更简单的XML集,以及更适合您的目的的XML集。从那里,您可以使用LINQ to XML从XML中获取所需的数据。这种方法的好处是它可以将网站与数据收集分离,这样当网站更改格式时,您只需更改XSLT即可匹配,无需其他任何操作。
