Re: [Rdfapi-php-interest] Missing some query results in XML results?

[<tob...@we...>]

Hi Ian,
sorry for the delay and thanks for this report. Richard is on holiday. I 
think i fixed the problem with the missing query results. Try to 
download the new version of the SparqlEngine which is now in the CVS 
repository.

Regards,
Tobias
