Hi,
So the query that I am trying to represent is: Is there a Book "Book1" that has a chapter 'c1' that cites some article 'a' and does this article 'a' have a chapter 'c2' which has a section 's' which has a figure 'f' which is called "Example semi-joins". This is a binary yes/no type of query.Given that $dblp is bound to the element DBLP, the following expression should return what you are looking for, and is I think self-explanatory:
exists( $dblp /Book[@rdf:about eq 'Book1'] /chapter /Chapter[@rdf:about eq 'c1']

/section /Section /cites[@rdf:resource eq 'a'] /../../../../../.. /Article[@rdf:about eq 'a'] /chapter /Chapter[@rdf:about eq 'c2'] /section /Section[@rdf:about eq 's'] /figure[. eq '"Example Semi-join"'] )
Regards,
