XmlNode.RemoveAll Method

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

[Visual Basic]
Public Overridable Sub RemoveAll()
[C#]
public virtual void RemoveAll();
[C++]
public: virtual void RemoveAll();
[JScript]
public function RemoveAll();

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 fire correctly, you must call the RemoveAll method of the base class.

Example

[Visual Basic, C#, C++] The following example removes all child and attribute nodes from the root node.
