이런 간단한 xml 데이터를 parser 의 delegate의 이벤트의 순서를 본다면..
1. 문서 파싱 시작
2. element (article) 을 시작태그 찾기
3. element(article) 의 attribute(author) 를 찾고, 값("John Doe") 를 구한다.
4. element(para)의 시작태그 찾기
5. characters 찾기 - This is a very short article.
6. element(para)의 끝태그 찾기
7. element(article)의 끝태그 찾기
8. 문서 파싱 종료
