touchXMLライブラリを使用してxmlを解析しようとしていますが、結果が得られません。コードは次のとおりです。
NSError *error = nil;
CXMLDocument *xmlParser = [[CXMLDocument alloc] initWithXMLString:dataString options:0 error:&error];
NSArray *resultNodes = NULL;
resultNodes = [xmlParser nodesForXPath:@"//entry" error:&error];
for (CXMLElement *resultElement in resultNodes) {
NSMutableDictionary *blogItem = [[NSMutableDictionary alloc] init];
int counter;
for(counter = 0; counter < [resultElement childCount]; counter++) {
[blogItem setObject:[[resultElement childAtIndex:counter] stringValue] forKey:[[resultElement childAtIndex:counter] name]];
}
}
メソッドnodesForXPath:は、resultNodes配列に0個のオブジェクトを残して何も返しません。dataStringで適切なxmlを取得しており、CXMLDocumentも適切に準備されています。デバッグを試みましたが、resultNodesで0オブジェクトを受け入れることがわかりません。また、NSErrorにも何も含まれていません(つまり、エラーは発生しません)。私が解析しようとしているxmlファイルは次のとおりです。
