.SH DESCRIPTION
The QDomDocumentFragment class is a tree of QDomNodes which is not usually 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(), QDomNode::replaceChild() and QDomNode::appendChild(): instead of inserting the fragment itself, all the fragment's children are inserted.
.PP
See also XML.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QDomDocumentFragment::QDomDocumentFragment ()"
Constructs an empty document fragment.
.SH "QDomDocumentFragment::QDomDocumentFragment ( const QDomDocumentFragment & x )"
Constructs a copy of \fIx\fR.
.PP
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().
.SH "QDomDocumentFragment::~QDomDocumentFragment ()"
Destroys the object and frees its resources.
.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 )"
Assigns \fIx\fR to this DOM document fragment.
.PP
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().
