How can I use HTML Agility Pack to retrive all the images from a website?

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.

Thank you very much for the help SO.

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));        


    }

Answer 1

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.

Answer 2

Based on their one example, but with modified XPath:

 HtmlDocument doc = new HtmlDocument();
 doc.Load("file.htm");
 foreach(HtmlNode link in doc.DocumentElement.SelectNodes("//img")
 {
    image_links[] = link["src"];
 }

I don't know this extension, so I'm not sure how to write out the array to somewhere else, but that will at least get you your data. (Also, I don't define the array correctly, I'm sure. Sorry).

Edit

Using your example:

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

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

        foreach(HtmlNode link in document.DocumentElement.SelectNodes("//img")
        {
          image_links[] = link["src"];
       }


    }
