title: SPARQLWrapper : problem in querying an ontology in a local file
body: <p>I'm working with SPARQLWrapper and I'm following the documentation. Here is my code:</p>
  
  <pre><code>queryString = "SELECT * WHERE { ?s ?p ?o. }"
  
  sparql = SPARQLWrapper("http://example.org/sparql")# I replaced this line with 
  sparql = SPARQLWrapper("file:///thelocation of my file in my computer")
  
  sparql.setQuery(queryString)
  
  try :
     ret = sparql.query()
     # ret is a stream with the results in XML, see &lt;http://www.w3.org/TR/rdf-sparql-XMLres/&gt;
  except :
     deal_with_the_exception()  
  </code></pre>
  
  <p>I'm getting these 2 errors:
  1- The system cannot find the path specified
  2- NameError: name 'deal_with_the_exception' is not defined</p>
