상기 오류는 toolbar가 먼저 구성되어 있는 상태에서 추가를 할 경우 발생하는 오류 입니다.

먼저 InputStream을 사용해서 생성한 폴더 assets에 접근해서 XML 파일을 open 합니다.
XmlPullParserFactory를 사용해서 신규 인터페이스를 생성합니다.
XmlPullParser를 생성해서 factory와 연결 후 xml파일을 로드합니다.
var xmlinfo:InputStream = assets.open("info.xml")
var factory:XmlPullParserFactory = XmlPullParserFactory.newInstance()
var parser:XmlPullParser = factory.newPullParser()
parser.setInput( xmlinfo, null)
전체 XML 파일을 확인하기 위해서 타입을 확인하고 END_DOCUMENT까지 로드를 반복합니다.
설정한 tag는 "bookinfo"이므로 if 문에서 "bookinfo"일 경우만 getAttributeValue를 사용해서 하위 로드에 접근합니다.
