Detailed Description
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(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()
Constructs an empty document fragment.
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().
QDomNode::NodeType QDomDocumentFragment::nodeType() const
Returns DocumentFragment.
