Querying a remote service with sparql AND selecting a graph fails (Solution included, but not tested for all but my use case)

[jbekesi]

Querying a remote service with sparql AND selecting a graph by URI fails, because
the match pattern for parsing the URL is greedy:

in rdflib/plugins/sparql/evaluate.py on line 347 (function evalServiceQuery the pattern
is "^service <(.*)>[ \n]*{(.*)}[ \n]*$",.

I changed this to "^service <(.*?)>[ \n]*{(.*)}[ \n]*$", and my use case worked.

The slightly changed example from https://rdflib.readthedocs.io/en/stable/intro_to_sparql.html#querying-a-remote-service will not work without the improved pattern:

qres = g.query(
    """
    SELECT ?s
    WHERE {
      SERVICE <https://dbpedia.org/sparql> {
         GRAPH <http://somegraph.uri.at> {
 
       ?s a ?o .
      }
    }
 }
    LIMIT 3
    """
