There was a problem hiding this comment.
xpath_nodes(path, namespaces).first? should work equally.

When you search for xpath_node and this node doesn't exist, will raise Enumerable::EmptyError.
I wondering if not found, just return nil.
Don't know if is the best approach to do that, maybe I can implement this in XML::XPathContext::evaluate
