I've found a solution, but I hope there's an easier way. I have to manually
Unassert each property; appended code below:
...
//Name
oProp =
oRdf.GetResource("http://mozilla.org/package/jgillick/switchproxy/rdf#name";)
;
oDs.Unassert(oProxy, oProp, oDs.GetTarget(oProxy, oProp, true));
//Id
oProp =
oRdf.GetResource("http://mozilla.org/package/jgillick/switchproxy/rdf#id";);
oDs.Unassert(oProxy, oProp, oDs.GetTarget(oProxy, oProp, true));
//Proxy Url
oProp =
oRdf.GetResource("http://mozilla.org/package/jgillick/switchproxy/rdf#proxy";
);
oDs.Unassert(oProxy, oProp, oDs.GetTarget(oProxy, oProp, true));
...
Is there an easier way to do all of this?
Thanks,
Jeremy
