public virtual void SetAttribute(
	string name,
	string value

The name of the attribute to create or alter. This is a qualified name. If the name contains a colon it is parsed into prefix and local name components.

Type: System.String

The value to set for the attribute.

Exception Condition

The specified name contains an invalid character.


The node is read-only.

If an attribute with the same name is already present in the element, its value is changed to that of value. value is a simple string. It is not parsed as it is being set. Any markup, such as syntax to be recognized as an entity reference, is treated as literal text and needs to be properly escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create an XmlAttribute node plus any XmlText and XmlEntityReference nodes, build the appropriate subtree and use SetAttributeNode to assign it as the value of an attribute.
