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 <code>Document</code> object could fulfill this role, a <code>Document</code> object can potentially be a heavyweight object, depending on the underlying implementation. What is really needed for this is a very lightweight object. <code>DocumentFragment</code> is such an object. <p>Furthermore, various operations -- such as inserting nodes as children of another <code>Node</code> -- may take <code>DocumentFragment</code> objects as arguments; this results in all the child nodes of the <code>DocumentFragment</code> being moved to the child list of this node. <p>The children of a <code>DocumentFragment</code> node are zero or more nodes representing the tops of any sub-trees defining the structure of the document. <code>DocumentFragment</code> 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 <code>DocumentFragment</code> might have only one child and that child node could be a <code>Text</code> node. Such a structure model represents neither an HTML document nor a well-formed XML document. <p>When a <code>DocumentFragment</code> is inserted into a <code>Document</code> (or indeed any other <code>Node</code> that may take children) the children of the <code>DocumentFragment</code> and not the <code>DocumentFragment</code> itself are inserted into the <code>Node</code>. This makes the <code>DocumentFragment</code> very useful when the user wishes to create nodes that are siblings; the <code>DocumentFragment</code> acts as the parent of these nodes so that the user can use the standard methods from the <code>Node</code> interface, such as <code>insertBefore</code> and <code>appendChild</code>. <p>See also the <a
