# qdomdocumentfragment(3qt)

Tree of QDomNodes which is not usually a complete QDomDocument

## NAME

QDomDocumentFragment - Tree of QDomNodes which is not usually a complete QDomDocument

## SYNOPSIS

All the functions in this class are reentrant when Qt is built with thread support.\</p\>

`#include <qdom.h>`

Inherits QDomNode.

### Public Members

**QDomDocumentFragment ()**\
 **QDomDocumentFragment ( const QDomDocumentFragment & x )**\
 **QDomDocumentFragment & operator= ( const QDomDocumentFragment & x )**\
 **~QDomDocumentFragment ()**\
 **virtual QDomNode::NodeType nodeType () const**\
 **virtual bool isDocumentFragment () const**\

## 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(), QDomNode::replaceChild() and QDomNode::appendChild(): instead of inserting the fragment itself, all the fragment's children are inserted.

See also XML.

## 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().
