|
The QDomNodeList class is a list of <a href="qdomnode.html">QDomNode</a> objects.
|
||
|
|
|
||
|
|
<p>
|
||
|
|
|
||
|
|
<p> Lists can be obtained by <a href="qdomdocument.html#elementsByTagName">QDomDocument::elementsByTagName</a>() and
|
||
|
|
<a href="qdomnode.html#childNodes">QDomNode::childNodes</a>(). The Document Object Model (DOM) requires
|
||
|
|
these lists to be "live": whenever you change the underlying
|
||
|
|
document, the contents of the list will get updated.
|
||
|
|
<p> You can get a particular node from the list with <a href="#item">item</a>(). The
|
||
|
|
number of items in the list is returned by <a href="#count">count</a>() (and by
|
||
|
|
<a href="#length">length</a>()).
|
||
|
|
<p> For further information about the Document Object Model see <a href="http://www.w3.org/TR/REC-DOM-Level-1/">http://www.w3.org/TR/REC-DOM-Level-1/</a> and <a href="http://www.w3.org/TR/DOM-Level-2-Core/">http://www.w3.org/TR/DOM-Level-2-Core/</a>. For a more general
|
||
|
|
introduction of the DOM implementation see the <a href="qdomdocument.html">QDomDocument</a>
|
||
|
|
documentation.
|
||
|
|
<p> <p>See also <a href="qdomnode.html#childNodes">QDomNode::childNodes</a>(), <a href="qdomdocument.html#elementsByTagName">QDomDocument::elementsByTagName</a>(), and <a href="xml-tools.html">XML</a>.

||
|
|
</h3>
|
||
|
|
Constructs a copy of <em>n</em>.

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

<h3 class=fn>uint <a name="count"></a>QDomNodeList::count () const
|
||
|
|
</h3>
|
||
|
|
|
||
|
|
<p> Returns the number of nodes in the list.
|

</h3>
|
||
|
|
Returns the node at position <em>index</em>.
|
||
|
|
<p> If <em>index</em> is negative or if <em>index</em> >= <a href="#length">length</a>() then a null
|
||
|
|
node is returned (i.e. a node for which <a href="qdomnode.html#isNull">QDomNode::isNull</a>() returns
|
||
|
|
TRUE).
|
||
|
|
<p> <p>See also <a href="#count">count</a>().
|
||
|
|
|

|
||
|
|
</h3>
|
||
|
|
Returns the number of nodes in the list.
|
||

|
||
|
|
Returns TRUE the node list <em>n</em> and this node list are not equal;
|
||
|
|
otherwise returns FALSE.
|
||
|
|
|
||
|
|
<h3 class=fn><a href="qdomnodelist.html">QDomNodeList</a> & <a name="operator-eq"></a>QDomNodeList::operator= ( const <a href="qdomnodelist.html">QDomNodeList</a> & n )
|
||
|
|
</h3>
|
||
|
|
Assigns <em>n</em> to this node list.
|
||
|
|
|
||
|
|
<h3 class=fn>bool <a name="operator-eq-eq"></a>QDomNodeList::operator== ( const <a href="qdomnodelist.html">QDomNodeList</a> & n ) const
|
||
|
|
</h3>
|
