QDomDocumentFragment stores a subtree of a document which does not necessarily represent a well-formed XML document. <p> 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. <p> The most important feature of QDomDocumentFragment is that it is treated in a special way by <a href="qdomnode.html#insertAfter">QDomNode::insertAfter</a>(), <a href="qdomnode.html#insertBefore">QDomNode::insertBefore</a>(), <a href="qdomnode.html#replaceChild">QDomNode::replaceChild</a>() and <a href="qdomnode.html#appendChild">QDomNode::appendChild</a>(): instead of inserting the fragment itself, all the fragment's children are inserted. <p>See also <a href="xml-tools.html">XML</a>. <hr><h2>Member Function Documentation</h2> <h3 class=fn><a name="QDomDocumentFragment"></a>QDomDocumentFragment::QDomDocumentFragment () </h3> Constructs an empty document fragment. <h3 class=fn><a name="QDomDocumentFragment-2"></a>QDomDocumentFragment::QDomDocumentFragment ( const <a href="qdomdocumentfragment.html">QDomDocumentFragment</a> & x ) </h3> Constructs a copy of <em>x</em>. <p> The data of the copy is shared (shallow copy): modifying one node will also change the other.
