.SH DESCRIPTION
The QDomDocumentFragment class is a tree of QDomNodes which is usually not a complete QDomDocument.
.PP
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.
.PP
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.
.PP
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 children of the fragment are inserted.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QDomDocumentFragment::QDomDocumentFragment ()"
Constructs an empty DocumentFragment.
.SH "QDomDocumentFragment::QDomDocumentFragment ( const QDomDocumentFragment & x )"
Copy constructor.
.PP
The data of the copy is shared: modifying one will also change the other. If you want to make a real copy, use cloneNode() instead.
.SH "QDomDocumentFragment::~QDomDocumentFragment ()"
Destructor.
.SH "bool QDomDocumentFragment::isDocumentFragment () const \fC[virtual]\fR"
This function reimplements QDomNode::isDocumentFragment().
.PP
See also nodeType() and QDomNode::toDocumentFragment().
.PP
Reimplemented from QDomNode.
.SH "QDomNode::NodeType QDomDocumentFragment::nodeType() const \fC[virtual]\fR"
Returns \fCDocumentFragment.\fR
.PP
See also isDocumentFragment() and QDomNode::toDocumentFragment().
.PP
Reimplemented from QDomNode.
.SH "QDomDocumentFragment& QDomDocumentFragment::operator= ( const QDomDocumentFragment & x )"
Assignment operator.
.PP
The data of the copy is shared: modifying one will also change the other. If
you want to make a real copy, use cloneNode() instead.
