The QDomDocumentFragment class is a tree of QDomNodes which is not usually a complete QDomDocument.
\inmodule QtXml
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.
| QDomDocumentFragment::QDomDocumentFragment | ( | ) |
| QDomDocumentFragment::QDomDocumentFragment | ( | const QDomDocumentFragment & | documentFragment | ) |
Constructs a copy of documentFragment.
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().
|
inline |
Returns DocumentFragment.
|
default |
Assigns other 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().
