XPath queries using HtmlAgilityPack fails to select notes with self closing tags

I'm trying to query all input nodes. All of the nodes that are not self-closing are being returned fine, but the nodes that are self-closing are not. Is there a way to address this that doesn't require me to changes the HTML?

Thanks!

This is the default behavior. If you want to change it, you need to play with the ElementFlags collection, and for example, just remove INPUT from it, just like I explained for OPTION on a similar question here on SO: XHTML Parsing with HTMLAgilityPack
