저는 XML 초보자이며 약간의 도움이 필요합니다.XML 데이터를 자바 스크립트 변수
xml 파일에서 하나의 데이터 만 추출하여 javascript 변수에 넣으 려면 수학 계산을 할 수 있습니다.
XML 파일은 다음과 같습니다

나는 유일한 통화 코드 = "978"이름 EUR/이름 BuyRateForeign 7,480000/BuyRateForeign 데이터 (값)를 추출합니다.
이 데이터 7,480000은 내게 중요하며 javascript 변수로 추출하여 number()로 변환하고 싶습니다. 그래서이 값으로 수학을 할 수 있습니다.
일부 코드를 시도했지만 화면에 게시 만되어 변수로 가져올 수 없습니다.
