c# - How to get img/src or a/hrefs using Html Agility Pack?

Question

I want to use the HTML agility pack to parse image and href links from a HTML page,but I just don't know much about XML or XPath.Though having looking up help documents in many web sites,I just can't solve the problem.In addition,I use C# in VisualStudio 2005.And I just can't speak English fluently,so,I will give my sincere thanks to the one can write some helpful codes.

Answer 1

The first example on the home page does something very similar, but consider:

 HtmlDocument doc = new HtmlDocument();
 doc.Load("file.htm"); // would need doc.LoadHtml(htmlSource) if it is not a file
 foreach(HtmlNode link in doc.DocumentElement.SelectNodes("//a[@href"])
 {
    string href = link["href"].Value;
    // store href somewhere
 }

So you can imagine that for img@src, just replace each a with img, and href with src. You might even be able to simplify to:

 foreach(HtmlNode node in doc.DocumentElement
              .SelectNodes("//a/@href | //img/@src")
 {
    list.Add(node.Value);
 }

For relative url handling, look at the Uri class.
