Detailed Description
The QDomDocumentFragment class is a tree of QDomNodes which is not usually a complete QDomDocument.
If you want to do complex tree operations it is useful to have a lightweight class to store nodes and their relations. QDomDocumentFragment stores a subtree of a document which does not necessarily represent a well-formed XML document.
QDomDocumentFragment is also useful if you want to group several nodes in a list and insert them all together as children of some node. In these cases QDomDocumentFragment can be used as a temporary container for this list of children.
The most important feature of QDomDocumentFragment is that it is treated in a special way by QDomNode::insertAfter(), QDomNode::insertBefore() and QDomNode::replaceChild(): instead of inserting the fragment itself, all the fragment's children are inserted.

Member Function Documentation
QDomDocumentFragment::QDomDocumentFragment ()
Constructs an empty document fragment.QDomDocumentFragment::QDomDocumentFragment ( const QDomDocumentFragment & x )
Constructs a copy of x.The data of the copy is shared (shallow copy): modifying one node will also change the other. If you want to make a deep copy, use cloneNode().
QDomDocumentFragment::~QDomDocumentFragment ()
Destroys the object and frees its resources.bool QDomDocumentFragment::isDocumentFragment () const [virtual]
This function reimplements QDomNode::isDocumentFragment().
See also nodeType() and QDomNode::toDocumentFragment().
Reimplemented from QDomNode.
QDomNode::NodeType QDomDocumentFragment::nodeType () const [virtual]
Returns DocumentFragment.
See also isDocumentFragment() and QDomNode::toDocumentFragment().
Reimplemented from QDomNode.
QDomDocumentFragment & QDomDocumentFragment::operator= ( const QDomDocumentFragment & x )
Assigns x to this DOM document fragment.The data of the copy is shared (shallow copy): modifying one node will also change the other. If you want to make a deep copy, use cloneNode().
