JAVA에서 XML 파일을 읽는 방법

Java에서 XML 파일을 읽는 것은 .docx 및 .txt와 같은 다른 파일을 읽는 것과 많이 다릅니다. XML 파일에는 태그 사이에 데이터가 포함되어 있기 때문입니다. Java는 XML 파일을 구문 분석하는 다양한 방법을 제공합니다. Java에는 XML 파일을 구문 분석하는 두 가지 구문 분석기가 있습니다.

자바 DOM 파서
자바 옳은 파서

Java DOM 파서

그만큼 DOM API XML 파일을 읽고 쓰는 클래스를 제공합니다. DOM API를 사용하여 노드를 생성, 삭제, 수정 및 재배치할 수 있습니다. DOM 파서는 전체 XML 파일을 구문 분석하고 DOM 기억 속의 물건. XML 파일을 모델링합니다. 트리 구조 쉽게 탐색하고 조작할 수 있습니다. DOM에서 XML 파일의 모든 내용은 마디 . 노드는 XML 파일의 구성 요소를 나타냅니다. DOM 파서는 느린 진행 중이며 점유하고 있습니다. 많은 기억 XML 파일을 메모리에 로드할 때.

Java에서 XML 파일을 읽는 프로세스를 따라야 합니다.

getDocumentElement()

getElementByTagName()

ELEMENT_NODE

getElementByTextValue()

Eclipse를 사용하여 Java에서 XML 파일을 읽는 단계

1 단계: 간단한 만들기 자바 프로젝트.

2 단계: 클래스 파일을 만들고 클래스 파일 이름을 제공합니다. 우리는 이름으로 클래스 파일을 만들었습니다. XML파일 읽기예1 .

3단계: 다음 코드를 작성하세요.

4단계: 다운로드 dom-2.3.0-jaxb-1.0.6.jar 파일: 여기를 클릭하세요...

5단계: 만들기 lib 프로젝트의 폴더입니다.

6단계: 복사 dom-2.3.0-jaxb-1.0.6.jar 파일을 lib 폴더에 붙여넣으세요.

7단계: 설정 수업 경로 :

자바 SAX 파서

Java SAX 파서는 다음을 의미합니다. 간단한 API ~을 위한 XML . SAX 파서가 XML 파일을 구문 분석합니다. 한 줄씩 . xml 파일에서 여는 태그, 닫는 태그 및 문자 데이터가 발견되면 이벤트를 트리거합니다. SAX 파서는 SAX 파서라고도 불린다. 이벤트 기반 파서 .

SAX 파서는 XML 파일을 메모리에 로드하지 않습니다. XML 문서의 개체 표현을 생성하지 않습니다. SAX 파서는 콜백 기능을 사용하여 클라이언트에게 XML 문서 구조를 알립니다. 그것은 더 빠르게 그리고 사용 적은 메모리 DOM 파서보다.

SAX는 스트리밍 인터페이스 XML의 경우 이는 XML 파일이 문서 상단부터 시작하여 루트 요소를 닫는 순서로 끝나는 순서대로 구문 분석함을 의미합니다.
