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;

public class Sample{

  public static void Main(){

    // Create the XML fragment to be parsed.

        </book>

    // Create the XmlNamespaceManager.
    XmlNamespaceManager nsmgr = new XmlNamespaceManager(new NameTable());

    // Create the XmlParserContext.
    XmlParserContext context = new XmlParserContext(null, nsmgr, null, XmlSpace.None);

    // Create the reader.
    XmlValidatingReader reader = new XmlValidatingReader(xmlFrag, XmlNodeType.Element, context);

    IXmlLineInfo lineInfo = ((IXmlLineInfo)reader);
