I am taking a stab at html agility pack and having trouble finding the right way to go about this.

For example:

var findclasses = _doc.DocumentNode.Descendants("div").Where(d => d.Attributes.Contains("class"));

However, obviously you can add classes to a lot more then divs so I tried this.. var allLinksWithDivAndClass = _doc.DocumentNode.SelectNodes("//*[@class=\"float\"]");

But that doesn't handle the cases where you add multiple classes and "float" is just one of them like this..

class="className float anotherclassName"

Is there a way to handle all of this? I basically want to select all nodes that have a class = and contains float.
