XmlNode.RemoveAll Method

Removes all the child nodes and/or attributes of the current node.

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

Syntax

Visual Basic

Public Overridable Sub RemoveAll

public virtual void RemoveAll()

Visual C++

public:
virtual void RemoveAll()

abstract RemoveAll : unit -> unit 
override RemoveAll : unit -> unit

Remarks

If a removed attribute is known to have a default value, an attribute immediately appears containing the default value and, if applicable, the corresponding namespace URI, local name, and prefix.

This method is a Microsoft extension to the Document Object Model (DOM).

Notes to Inheritors

When overriding RemoveAll in a derived class, in order for events to be raised correctly, you must call the RemoveAll method of the base class.

Examples

The following example removes all child and attribute nodes from the root node.
