IXmlLineInfo 인터페이스

정의

클래스에서 줄과 위치 정보를 반환할 수 있는 인터페이스를 제공합니다.Provides an interface to enable a class to return line and position information.

예제

다음 예제에서는 XML 조각을 구문 분석합니다.The following example parses an XML fragment. 수준, 줄 번호 및 줄 위치를 포함 하 여 각 노드에 표시 됩니다.Each node is displayed, including its depth, line number, and line position.
