.SH DESCRIPTION
The QDomNodeList class is a list of QDomNode objects.
.PP
Lists can be obtained by QDomDocument::elementsByTagName() and QDomNode::childNodes(). 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.
.PP
For further information about the Document Objct Model see http://www.w3.org/TR/REC-DOM-Level-1/. For a more general introduction of the DOM implementation see the QDomDocument documentation.
.PP
See also QDomNode::childNode() and QDomDocument::elementsByTagName().
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QDomNodeList::QDomNodeList ()"
Creates an empty node list.
.SH "QDomNodeList::QDomNodeList ( const QDomNodeList & n )"
Copy constructor.
.SH "QDomNodeList::~QDomNodeList () \fC[virtual]\fR"
Destructor.
.SH "uint QDomNodeList::count () const"
Returns the number of nodes in the list.
.PP
This function is the same as length().
.SH "QDomNode QDomNodeList::item ( int index ) const \fC[virtual]\fR"
Returns the node at position \fIindex.\fR
.PP
If \fIindex\fR is negative or if \fIindex\fR >= length() then a null node is returned (i.e. a node for which QDomNode::isNull() returns TRUE).
.SH "uint QDomNodeList::length () const \fC[virtual]\fR"
Returns the number of nodes in the list.
.PP
This function is the same as count().
.SH "bool QDomNodeList::operator!= ( const QDomNodeList & n ) const"
Returns TRUE if both lists are not equal, otherwise FALSE.
.SH "QDomNodeList& QDomNodeList::operator= ( const QDomNodeList & n )"
Assigns another node list to this object.
.SH "bool QDomNodeList::operator== ( const QDomNodeList & n ) const"
Returns TRUE if both lists are equal, otherwise FALSE.
.SH "QDomNodeList::QDomNodeList ( QDOM_NodeListPrivate * p )"
For internal use only.
