add_attribute
add_attribute( key, value=nil )
public
Adds an attribute to this element, overwriting any existing attribute by the same name.
key |
can be either an Attribute or a String. If an Attribute, the attribute is added to the list of Element attributes. If String, the argument is used as the name of the new attribute, and the value parameter must be supplied. |
value |
Required if key is a String, and ignored if the first argument is an Attribute. This is a String, and is used as the value of the new Attribute. This should be the unnormalized value of the attribute (without entities). |
