IXmlLineInfo Interface
Visual Studio 2010
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.
#using <System.Xml.dll> using namespace System; using namespace System::IO; using namespace System::Xml; int main() { // Create the XML fragment to be parsed. String^ xmlFrag = "<book>\n" "<misc>\n" "<style>paperback</style>\n" "<pages>240</pages>\n" "</misc>\n" "</book>\n"; // Create the XmlNamespaceManager. XmlNamespaceManager^ nsmgr = gcnew XmlNamespaceManager( gcnew NameTable ); // Create the XmlParserContext. XmlParserContext^ context = gcnew XmlParserContext( nullptr,nsmgr,nullptr,XmlSpace::None ); // Create the reader. XmlValidatingReader^ reader = gcnew XmlValidatingReader( xmlFrag,XmlNodeType::Element,context ); IXmlLineInfo^ lineInfo = (dynamic_cast<IXmlLineInfo^>(reader)); if ( lineInfo->HasLineInfo() ) { // Parse the XML and display each node. while ( reader->Read() ) { switch ( reader->NodeType ) { case XmlNodeType::Element: Console::Write( " {0} {1}, {2} ", reader->Depth, lineInfo->LineNumber, lineInfo->LinePosition ); Console::WriteLine( "< {0}>", reader->Name ); break; case XmlNodeType::Text: Console::Write( " {0} {1}, {2} ", reader->Depth, lineInfo->LineNumber, lineInfo->LinePosition ); Console::WriteLine( " {0}", reader->Value ); break; case XmlNodeType::EndElement: Console::Write( " {0} {1}, {2} ", reader->Depth, lineInfo->LineNumber, lineInfo->LinePosition ); Console::WriteLine( "</ {0}>", reader->Name ); break; } } } // Close the reader. reader->Close(); }
