<code>DocumentFragment</code> is a "lightweight" or "minimal"
<code>Document</code> object. 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 href='http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113'>Document Object Model (DOM) Level 2 Core Specification</a>.
