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 casesQDomDocumentFragment
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 byinsertAfter()
,insertBefore()
,replaceChild()
andappendChild()
: instead of inserting the fragment itself, all the fragment’s children are inserted.
