Question

I just downloaded the HTMLAgilityPack and the documentation doesn’t have any examples.

I’m looking for a way to download all the images from a website. The address strings, not the physical image.

<img src="blabalbalbal.jpeg" />

I need to pull the source of each img tag. I just want to get a feel for the library and what it can offer. Everyone said this was the best tool for the job.

Edit

public void GetAllImages()
    {
        WebClient x = new WebClient();
        string source = x.DownloadString(@"http://www.google.com");

        HtmlAgilityPack.HtmlDocument document = new HtmlAgilityPack.HtmlDocument();
        document.Load(source);

                         //I can't use the Descendants method. It doesn't appear.
        var ImageURLS = document.desc
                   .Select(e => e.GetAttributeValue("src", null))
                   .Where(s => !String.IsNullOrEmpty(s));        
    }

You can do this using LINQ, like this:

var document = new HtmlWeb().Load(url);
var urls = document.DocumentNode.Descendants("img")
                                .Select(e => e.GetAttributeValue("src", null))
                                .Where(s => !String.IsNullOrEmpty(s));

EDIT: This code now actually works; I had forgotten to write document.DocumentNode.
