How do I correctly grab the images I scrape with HtmlAgilityPack?
c# html-agility-pack web-scraping xpath
Question
I am currently working on a project and I am learning HAP as I go. I get the basics of it and it seems like it could be very powerful.
I'm having an issue right now, I am trying to scrape a product on this one website and get the links to the images but I dont know how to extract the link from the xpath. I used to do this with Regex which was alot easier but I am moving on this HAP.
This is my current code I dont think it will be very useful to see but i'll out it in either way.
private static void HAP()
{
var url = "https://www.dhgate.com/product/brass-hexagonal-fidget-spinner-hexa-spinner/403294406.html#gw-0-4|ff8080815e03d6df015e9394cc681f8a:ff80808159abe8a5015a3fd78c5b51bb";
// HtmlWeb - A Utility class to get HTML document from http
var web = new HtmlWeb();
//Load() Method download the specified HTML document from an Internet resource.
var doc = web.Load(url);
var rootNode = doc.DocumentNode;
var divs = doc.DocumentNode.SelectNodes(String.Format("//IMG[@src='{0}']", "www.dhresource.com/webp/m/100x100/f2/albu/g5/M00/14/45/rBVaI1kWttaAI1IrAATeirRp-t8793.jpg"));
Console.WriteLine(divs);
Console.ReadLine();
}
This is the link I am scraping from
And this should be the xPath of the first image.
//IMG[@src='//www.dhresource.com/webp/m/100x100s/f2-albu-g5-M00-6E-20-rBVaI1kWtmmAF9cmAANMKysq_GY926.jpg/2017-led-light-up-hand-spinners-fidget-spinner.jpg']

I create a helper method for this. I had to get the node, and then the attribute and then cycle through the attribute to get all the links.
private static void HAP()
{
//Declare the URL
var url = "https://www.dhgate.com/product/brass-hexagonal-fidget-spinner-hexa-spinner/403294406.html#gw-0-4|ff8080815e03d6df015e9394cc681f8a:ff80808159abe8a5015a3fd78c5b51bb";
// HtmlWeb - A Utility class to get HTML document from http
var web = new HtmlWeb();
//Load() Method download the specified HTML document from an Internet resource.
var doc = web.Load(url);
var rootNode = doc.DocumentNode;
var nodes = doc.DocumentNode.SelectNodes("//img");
foreach (var src in nodes)
{
var links = src.Attributes["src"].Value;
Console.WriteLine(links);
}
Console.ReadLine();
}
