See the snippet below. When parsing with this parser we'd get 9 statements (mostly blank nodes). I'd expect an error though.

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
        "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
  <table>
    <tr>
      <td>some col 1</td>
      <td>some col 2</td>
      <td>some col 3</td>
    </tr>
   </table>
</body>
</html>

I don't think this should throw an error though (will double-check), as this is valid XML, just without any RDF triples.

In any case, no blank nodes should be emitted AFAICS, so something seems to be going wrong there.

I just went through the RDF/XML spec again, and as far as I can see, this should actually be valid RDF/XML. So the parser returns correct output here.

Concretely:

  • html is the root, which is at the same time a Typed Node Element, which forms _:b a <...html>
  • body is a Property Element, which forms _:b1 <...body> _:b2.
  • table is a Typed Node Element
  • tr is a Property Element
  • ...
