HTML Agility pack - parsing img src and href from relative paths

c# html-agility-pack

Question

I have a piece of HTML that uses relative paths for the image src and link href. Using HTML Agility Pack, I need to change from a relative to a full url route, such as "http://localhost:port.."

src="/Expo/imagename.s3lb" in S3 href="../Etch/Exposition/...aspx?sflang=en"

Can you provide me instructions on how to accomplish it? Thanks.

Accepted Answer

Currently, I am unable to test or execute this, but you might attempt something similar:

var htmlStr = "yourhtml";
var doc = new HtmlDocument();
doc.LoadHtml(htmlStr);
var baseUri = new Uri("baseUriOfYourSite");
var images = doc.DocumentNode.SelectNodes("//img/@src").ToList();
var links = doc.DocumentNode.SelectNodes("//a/@href").ToList();
foreach (var item in images.Concat(links))
{
    item.InnerText =  new Uri(baseUri, item.InnerText).AbsoluteUri;    
}
