## 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(), QDomNode::replaceChild() and QDomNode::appendChild(): 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().

### QDomNode::NodeType QDomDocumentFragment::nodeType () const

Returns `DocumentFragment`.

See also isDocumentFragment() and QDomNode::toDocumentFragment().

### 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().
