IHasXmlNode Interface
Enables a class to return an XmlNode from the current context or position.
Assembly: System.Xml (in System.Xml.dll)
The IHasXmlNode type exposes the following members.
The IHasXmlNode interface provides an interface that enables a class to return an XmlNode from the current context or position. It is implemented by XPathNavigator objects that operate over classes that have XmlNode nodes. For example, if the XPathNavigator object is created by an XmlDocument, you can use the GetNode method to return the XmlNode representing the current position of the navigator.
The following example uses the GetNode method to retrieve and modify the selected node.
#using <System.Xml.dll> using namespace System; using namespace System::IO; using namespace System::Xml; using namespace System::Xml::XPath; int main() { XmlDocument^ doc = gcnew XmlDocument; doc->Load( "books.xml" ); // Create an XPathNavigator and select all books by Plato. XPathNavigator^ nav = doc->CreateNavigator(); XPathNodeIterator^ ni = nav->Select("descendant::book[author/name='Plato']"); ni->MoveNext(); // Get the first matching node and change the book price. XmlNode^ book = dynamic_cast<IHasXmlNode^>(ni->Current)->GetNode(); book->LastChild->InnerText = "12.95"; Console::WriteLine( book->OuterXml ); }
The example uses the file books.xml as input.
