Select HTML node only when it has no class

I'm using HTMLAgilityPack to grab a bunch of a tags. Some of the have 1 of several classes assigned and some have no class. It's those with no class that I need to grab.

I know that to grab a node by class we can do something like;

.SelectNodes("//table[@class=\"pagelinks\"]");

Similarly you can choose to ignore specific classes or id's with;

.SelectNodes("//table[not(@class=\"pagelinks\")]");

But is there a way to only grab a node when and only when it has no class?

This XPath will select tables that either have no class attribute, or that have a class attribute that is entirely whitespace (or blank):

//table[not(normalize-space(@class))]

The following code should select when there's no class attribute defined at all:

.SelectNodes("//table[not(@class)]");
