IXmlLineInfo Interface
Provides an interface to enable a class to return line and position information.
Assembly: System.Xml (in System.Xml.dll)
The IXmlLineInfo type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() ![]() | LineNumber | Gets the current line number. |
![]() ![]() ![]() | LinePosition | Gets the current line position. |
The following example parses an XML fragment. Each node is displayed, including its depth, line number, and line position.
Imports System Imports System.IO Imports System.Xml Imports Microsoft.VisualBasic public class Sample public shared sub Main() ' Create the XML fragment to be parsed. Dim xmlFrag as string = "<book>" + Chr(10) & _ " <misc>" + Chr(10) & _ " <style>paperback</style>" + Chr(10) & _ " <pages>240</pages>" + Chr(10) & _ " </misc>" + Chr(10) & _ "</book>" ' Create the XmlNamespaceManager. Dim nsmgr as XmlNamespaceManager = new XmlNamespaceManager(new NameTable()) ' Create the XmlParserContext. Dim context as XmlParserContext = new XmlParserContext(nothing, nsmgr, nothing, XmlSpace.None) ' Create the reader. Dim reader as XmlValidatingReader = new XmlValidatingReader(xmlFrag, XmlNodeType.Element, context) Dim lineInfo as IXmlLineInfo = CType(reader, IXmlLineInfo) if (lineInfo.HasLineInfo()) ' Parse the XML and display each node. while (reader.Read()) select case reader.NodeType case XmlNodeType.Element: Console.Write("{0} {1},{2} ", reader.Depth, lineInfo.LineNumber, lineInfo.LinePosition) Console.WriteLine("<{0}>", reader.Name) case XmlNodeType.Text: Console.Write("{0} {1},{2} ", reader.Depth, lineInfo.LineNumber, lineInfo.LinePosition) Console.WriteLine(" {0}", reader.Value) case XmlNodeType.EndElement: Console.Write("{0} {1},{2} ", reader.Depth, lineInfo.LineNumber, lineInfo.LinePosition) Console.WriteLine("</{0}>", reader.Name) end select end while end if ' Close the reader. reader.Close() end sub end class
