XPathNavigator.DeleteRange Method

Deletes a range of sibling nodes from the current node to the node specified.

Namespace:  System.Xml.XPath
Assembly:  System.Xml (in System.Xml.dll)

public virtual void DeleteRange(
	XPathNavigator lastSiblingToDelete


Type: System.Xml.XPath.XPathNavigator
An XPathNavigator positioned on the last sibling node in the range to delete.


The XPathNavigator specified is null.


The XPathNavigator does not support editing.


The last node to delete specified is not a valid sibling node of the current node.

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 = new XmlDocument();
XPathNavigator navigator = document.CreateNavigator();

XmlNamespaceManager manager = new XmlNamespaceManager(document.NameTable);
manager.AddNamespace("bk", "");

XPathNavigator first = navigator.SelectSingleNode("/bk:bookstore/bk:book[1]", manager);
XPathNavigator last = navigator.SelectSingleNode("/bk:bookstore/bk:book[2]", manager);


The example takes the contosoBooks.xml file as an input.
