The DeleteRange method deletes a range of sibling nodes from the current node the XPathNavigator is positioned on (inclusive) to the node specified by the XPathNavigator parameter (inclusive). The XPathNavigator is then positioned on its parent node.
In the following example, the first and second book elements of the contosoBooks.xml file are deleted using the DeleteRange method.
XmlDocument^ document = gcnew XmlDocument(); document->Load("contosoBooks.xml"); XPathNavigator^ navigator = document->CreateNavigator(); XmlNamespaceManager^ manager = gcnew XmlNamespaceManager(document->NameTable); manager->AddNamespace("bk", "http://www.contoso.com/books"); XPathNavigator^ first = navigator->SelectSingleNode("/bk:bookstore/bk:book[1]", manager); XPathNavigator^ last = navigator->SelectSingleNode("/bk:bookstore/bk:book[2]", manager); navigator->MoveTo(first); navigator->DeleteRange(last); Console::WriteLine(navigator->OuterXml);
The example takes the contosoBooks.xml file as an input.
