Better type in error conected to usage of Options #17

type xmlc.XMLNode = unsafe &void

for id in ids {
        mut node := none as ?xmlc.XMLNode

        for potential_node in nodes {
            if get_attribute_value(potential_node, "id") == id {
                node = potential_node
                break
            }
        }

        }
        
        name := get_attribute_value(node, "name") or { panic("Typedef node is corrupted - doesn't have name attribute") }
}
