## 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.
