[OWSLib-users] CatalogueServiceWeb and data.gov exception

[Davide Muraro]

Dear All,


I was doing some tests using CatalogueServiceWeb and the data.gov CSW.


Basically doing something like:


from owslib.csw import CatalogueServiceWeb
from owslib.fes import PropertyIsEqualTo, PropertyIsLike, BBox
csw = CatalogueServiceWeb('http://catalog.data.gov/csw?service=CSW&version=2.0.2&request=GetCapabilities')
query = PropertyIsEqualTo('csw:AnyText', 'map')
csw.getrecords2(constraints=[query], maxrecords=20)
print(csw.records)

i got:

*python3.5/site-packages/owslib/csw.py in getrecords2(self, constraints, sortby, typenames, esn, outputschema, format, startposition, maxrecords, cql, xml, resulttype)
    380
    381             # process search results attributes
--> 382             val = self._exml.find(util.nspath_eval('csw:SearchResults', namespaces)).attrib.get('numberOfRecordsMatched')
    383             self.results['matches'] = int(util.testXMLValue(val, True))
    384             val = self._exml.find(util.nspath_eval('csw:SearchResults', namespaces)).attrib.get('numberOfRecordsReturned')

AttributeError: 'NoneType' object has no attribute 'attrib'


Ideas?
