<h1>DocumentFragment Class Reference</h1>
<code>from PyKDE4.khtml import *</code>
<p>
Inherits: <a href="../khtml/DOM.Node.html">DOM.Node</a><br />
Namespace: <a href="../khtml/DOM.html">DOM</a><br />
<h2>Detailed Description</h2>
<p>DocumentFragment is a "lightweight" or "minimal"
Document 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 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.
</p>
<p>
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.
</p>
<p>
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.
</p>
<p>
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() .
