Sample applications:* Page fixing or generation. You can fix a page the way you want, modify the DOM, add nodes, copy nodes, you name it.* Web scanners. You can easily get to img/src or a/hrefs with a bunch XPATH queries.* Web scrapers. You can easily scrap any existing web page into an RSS feed for example, with just an XSLT file serving as the binding. An example of this is provided.
There is no dependency on anything else than .Net's XPATH implementation. There is no dependency on Internet Explorer's dll or tidy or anything like that. There is also no adherence to XHTML or XML, although you can actually produce XML using the tool.
For example, here is how you would fix all hrefs in an HTML file:
HtmlDocument doc = new HtmlDocument();
foreach(HtmlNode link in doc.DocumentElement.SelectNodes("//a[@href"])
HtmlAttribute att = link["href"];
att.Value = FixLink(att);
