xml 파일에서 내 BlackBerry 앱의 데이터를 가져오고 싶습니다. 나는 reseach하고 kxml2를 사용하는 것이 최선의 선택임을 알아 냈습니다. 그러나 Blackberry에서 예제 코드를 찾을 수 없습니다. kxml2.jar을 열면 xmlParser와 kxmlParser가 표시됩니다. 어느 것을 사용해야합니까?kxml2는 블랙 베리의 xml 파일을 구문 분석합니다.
kxml2 사용법을 명확하게 설명 할 수 있습니까?
정상적인 XML 파싱과의 ListField 샘플에 표시하는 것은 여기에 ..

Full Project가 여기에있다 .. 기본에서이 너무 복잡 가야하지 않습니다.
