HTML Agility Pack

Question

I'm trying to use HTML Agility Pack to get the description text from inside the:

<meta name="description" content="**this is the text i want to extract and store in a string**" />

And someone on Stackoverflow a little while ago suggested I use HTMLAgilityPack. But I don't know how to use it, and the documentation for it that I've found (including the docs contained in the downloads) all have invalid links and therefor cannot view the documentation.

Can somebody please help me solve this?

The usage is very similar to XmlDocument; you could use MSDN on XmlDocument for a broad overview; you might also want to learn xpath syntax (MSDN).

Example:

HtmlDocument doc = new HtmlDocument();
doc.Load(path); // or .LoadHtml(html);
HtmlNode node = doc.DocumentNode.SelectSingleNode("//meta[@name='description']");
if (node != null) {
    string desc = node.GetAttributeValue("content", "");
    // TODO: write desc somewhere
}

The second argument to GetAttributeValue is the default returned in case the attribute is not found.
