Detailed Description

TheQDomDocumentFragment class is a tree of QDomNodes which is not usually a completeQDomDocument.

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 casesQDomDocumentFragment can be used as a temporary container for this list of children.

The most important feature ofQDomDocumentFragment is that it is treated in a special way byQDomNode::insertAfter(),QDomNode::insertBefore(),QDomNode::replaceChild() andQDomNode::appendChild(): instead of inserting the fragment itself, all the fragment's children are inserted.

QDomDocumentFragment::QDomDocumentFragment(constQDomDocumentFragment & x)

Constructs a copy ofx.

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, usecloneNode().

QDomNode::NodeType QDomDocumentFragment::nodeType() const

ReturnsDocumentFragment.

See alsoisDocumentFragment() andQDomNode::toDocumentFragment().

QDomDocumentFragment & QDomDocumentFragment::operator=(constQDomDocumentFragment & x)

Assignsx 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, usecloneNode().
