IXmlLineInfo Interface

Provides an interface to enable a class to return line and position information.

Namespace: System.Xml
Assembly: System.Xml (in system.xml.dll)

public interface IXmlLineInfo
public interface IXmlLineInfo
public interface IXmlLineInfo

The following example parses an XML fragment. Each node is displayed, including its depth, line number, and line position.

using System;
using System.IO;
using System.Xml;
