html agility section selecting

Question

I need to get the HTML in between 2 section tags like this:

<section class="image-section">
//images here...
</section>

I am using HTML Agility to do this and though this would work:

HtmlNode sec = document.DocumentNode.SelectNodes("//*[@class='image-section'")

but this does not. How would I get the HTML snippet I want?

Answer 1

Assuming that we have following html:

<!DOCTYPE html>
<html>
   <body>
      <h1>Test</h1>
      <section class="image-section">
         <img src="image1.jpg">
         <img src="image2.jpg">
      </section>
   </body>
</html>

Here is a code:

class Program
    {
        static void Main(string[] args)
        {
            var html = File.ReadAllText(@"d:/my.html");

            var htmlDoc = new HtmlDocument();
            htmlDoc.LoadHtml(html);

            HtmlNodeCollection sections = htmlDoc.DocumentNode.SelectNodes("//*[@class='image-section']");
            var section = sections.FirstOrDefault();
            if (section != null)
            {
                foreach (var imgElement in section.Elements("img"))
                {
                    Console.WriteLine(imgElement.OuterHtml);
                }
            }

            Console.ReadKey();
        }
    }

Output:

<img src="image1.jpg">
<img src="image2.jpg">
