Answer 1

Your default namespace (which is what entry appears to use) is http://www.w3.org/2005/Atom as specified by:

xmlns="http://www.w3.org/2005/Atom"

Answer 2

NSDictionary *nameSpace=[NSDictionary dictionaryWithObjectsAndKeys: @"http://www.w3.org/2005/Atom",@"xmlns", @"http://www.georss.org/georss",@"georss", @"http://a9.com/-/spec/opensearchrss/1.0/",@"openSearch", @"http://schemas.google.com/blogger/2008",@"blogger", @"http://schemas.google.com/g/2005",@"gd", @"http://purl.org/syndication/thread/1.0",@"thr", nil]; resultNodes=[xmlDoc nodesForXPath:@"//xmlns:feed//xmlns:entry" namespaceMappings:nameSpace error:&error];
