Subject: Clarification needed regarding the DOM Level
1 specification.
This is with regards to the DOM Level 1 specification
that has been published on October 1 1998.
In the NamedNodeMap there is a method called
removeNamedItem which is described in the document as
follows:
removeNamedItem
Removes a node specified by name. If the removed
node is an Attr with a default value it is
immediately replaced.
Parameters
name
The name of a node to remove.
Return Value
The node removed from the map or null if no
node with such a name exists.
Exceptions
DOMException
NOT_FOUND_ERR: Raised if there is no node
named name in the map.
In the method above it is observed that the return
value is'null' if no node with such a name exists and
immediately after it is the exceptions raised which
has DOMException raised if there is no node named
'name' in the NamedNodeMap. It is unclear what should
be the right thing to do here, that is throw an
exception or return value null incase the node isn't
present in the NamedNodeMap.
In most of the cases in the DOM level 1 specification
in such situations the return value is null and the
exceptions that are raised is
NO_MODIFICATION_ALLOWED_ERR.
Shouldn't the same apply to this method also?
Need clarification regarding this.
Regards
Rajiv
