Hey All,

I have a problem parsing websites with GRDDL.

I use this code:

Model m = ModelFactory.createDefaultModel();
RDFReader r = m.getReader("GRDDL");
r.setProperty("grddl.rdfa", true);
r.read(m, "some website...");

And get the exception pasted at the end.

Most of the times when I download the html file locally and delete the first
line about DOCTYPE it works just fine. But how can I overcome this?

Thanks,
Stijn
