How about using the DOM UserData mechanism to store each of your wrapper nodes against the node that it wraps. This way, before you make a new wrapper node, you can check if you already have one for that node and use it instead.
As an added benefit, you can also register a UserDataHandler that will get notified when the original node is deleted, giving you an easy way to tell when to release your wrapper node. -Nathan ------------------------ Nathan Codding PureEdge Solutions Inc http://www.PureEdge.com -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 05, 2003 9:47 AM To: [EMAIL PROTECTED] Subject: Re: Append Child, Insert Before, Remove Child, and Replace Child Don't everybody answer at once ;-) I apologize if this question is obvious or inappropriate, but it is a behavior of the parser that I haven't been able to definitively classify yet. So, if anyone could offer any help I would really appreciate it. The reason that is an issue for me is that I have my own representation of every node (a wrapper node). So, if a node is returned, I need to create a new wrapper node. Now, if I create a new node wrapper for a duplicate node, then it could end up getting released right out from under the second node without me knowing it....not to mention that it is unnecessary.

My question is whether the return value is always the same as the input value. For example, if I pass DOMNode foo to replaceChild as the OldChild, will the return value of the function always be foo? I need to know if my code needs to check for the return value or if I can assume that the value is always the same. Note: In the past I had been led to believe that they were always the same, but I wanted to check this before my code goes beta.
