Use XPATH notation to match against flattened nodes

The generated code would look like `<code>impl <a href="...">Foo</a></code>`
which the plain text matcher doesn't match. But by using the XPATH notation, the
nodes are flattened and we can correctly assert that `impl Foo` does not occur
in the generated docs.
