[redland-dev] xpath query

[Jagdev Bhogal]

Dear all
I have a c-program which currently parses an rdf file and retrieves all of the nodes using:
 
const char *query_string="select ?label, ?comment from <C:/datafile.rdf> where (?x rdf:type rdfs:Class) (?x rdfs:label ?label) (?x rdfs:comment ?comment) using rdf for <http://www.w3.org/1999/02/22-rdf-syntax-ns#>,rdfs for <http://www.w3.org/2000/01/rdf-schema#>";

Lets say I have a string defined as:
 
char keyword[]="City";
 
My question is can we have a where clause in the query, so that we only retrieve results where the strcmp(label, keyword) = 0 in other words only retrieve those results where the label is equal to the keyword which in this case is "City". 
 
If further explanation is needed let me know.
Thank you
Jagdev
