XmlDocument.changeNodeOwner(): alternative method in w3c?

[SAFROLE]

Using Sun's XmlDocument, you have a method named changeNodeOwner( Node node), which allows you to set the parent of the node argument and all of its children. I need to change the code we have from Sun to w3c standards, but the Document class provided by w3c does not have this method. Is there an alternatove method to set the parent of a node?

Thanks.
