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> 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>.

||
|
|
<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. If you want to make a <a href="shclass.html#deep-copy">deep copy</a>, use
|
||
|
|
<a href="qdomnode.html#cloneNode">cloneNode</a>().
|

|
|
|
||
|
|
<h3 class=fn><a name="~QDomDocumentFragment"></a>QDomDocumentFragment::~QDomDocumentFragment ()
|
||
|
|
</h3>
|
||
|
|
Destroys the object and frees its resources.
|
||
|
|
|
||
|
|
<h3 class=fn>bool <a name="isDocumentFragment"></a>QDomDocumentFragment::isDocumentFragment () const<tt> [virtual]</tt>
|

</h3>
|
||
|
|
This function reimplements <a href="qdomnode.html#isDocumentFragment">QDomNode::isDocumentFragment</a>().

</h3>
|
||
|
|
Returns <tt>DocumentFragment</tt>.

Assigns <em>x</em> to this DOM document fragment.
