XPath to find elements that does not have an id or class

xpath

Solution

Pretty straightforward:

//tr[not(@id) and not(@class)]

That will give you all `tr` elements lacking both `id` and `class` attributes. If you want all `tr` elements lacking one of the two, use `or` instead of `and`:

//tr[not(@id) or not(@class)]

When attributes and elements are used in this way, if the attribute or element has a value it is treated as if it's true. If it is missing it is treated as if it's false.
