It is -very common to want to be able to extract a portion of a document's -tree or to create a new fragment of a document. Imagine implementing a -user command like cut or rearranging a document by moving fragments -around. It is desirable to have an object which can hold such fragments -and it is quite natural to use a Node for this purpose. While it is -true that a Document object could fulfil this role, a Document object -can potentially be a heavyweight object, depending on the underlying -implementation. What is really needed for this is a very lightweight -object. DocumentFragment is such an object. - -Furthermore, various operations -- such as inserting nodes as children -of another Node -- may take DocumentFragment objects as arguments; this -results in all the child nodes of the DocumentFragment being moved to -the child list of this node. - -The children of a DocumentFragment node are zero or more nodes -representing the tops of any sub-trees defining the structure of the -document. DocumentFragment nodes do not need to be well-formed XML -documents (although they do need to follow the rules imposed upon -well-formed XML parsed entities, which can have multiple top nodes). -For example, a DocumentFragment might have only one child and that -child node could be a Text node. Such a structure model represents -neither an HTML document nor a well-formed XML document. - -When a DocumentFragment is inserted into a Document (or indeed any -other Node that may take children) the children of the DocumentFragment -and not the DocumentFragment itself are inserted into the Node. This -makes the DocumentFragment very useful when the user wishes to create -nodes that are siblings; the DocumentFragment acts as the parent of -these nodes so that the user can use the standard methods from the Node -interface, such as insertBefore() and appendChild().
