이 그리고 지금은 현재 타임 스탬프하지만 난과 <xmp:ModifyDate>2017-05-25T20:23:38-05:00</xmp:ModifyDate>을 수정하고자 아래의 말 그대로 문자열 파싱을하지 않고 실제로 어떻게하는지 모릅니다. xmp를 수정할 수있는 라이브러리가 있습니까?

수정일을 관리 할 수 없으며 관리해서는 안됩니다. iText는 파일을 조작 할 때마다 컴퓨터의 시계 시간에 따라 자동으로 날짜를 변경합니다. –

그것은 단지 예일뿐입니다. 다른 속성도 수정하고 싶습니다. –

어떤 iText 버전을 사용하고 있습니까? iText 5와 iText 7은 상당히 다릅니다. –

마지막으로 iText 라이브러리에서 XmpReader.replaceNode를 사용했습니다.
