<h2>Detailed Description</h2>
<p>The QDomDocumentFragment class is a tree of QDomNodes which is not usually a complete <a href="qdomdocument.html">QDomDocument</a>.</p>
<p>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.</p>
<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>
<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>

<h2>Member Function Documentation</h2>
<!-- $$$QDomDocumentFragment[overload1]$$$QDomDocumentFragment -->
<h3 class="fn"><a name="QDomDocumentFragment"></a>QDomDocumentFragment::<span class="name">QDomDocumentFragment</span> ()</h3>
<p>Constructs an empty document fragment.</p>

<h3 class="fn"><a name="QDomDocumentFragment-2"></a>QDomDocumentFragment::<span class="name">QDomDocumentFragment</span> ( const <span class="type">QDomDocumentFragment</span> &amp; <i>x</i> )</h3>
<p>Constructs a copy of <i>x</i>.</p>
<p>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 <a href="qdomnode.html#cloneNode">cloneNode</a>().</p>
