## Detailed Description

The QDomNodeList class is a list of QDomNode objects.

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.

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.

See also QDomNode::childNode() and QDomDocument::elementsByTagName().

## Member Function Documentation

### QDomNodeList::QDomNodeList ()

Creates an empty node list.

### QDomNodeList::QDomNodeList ( const QDomNodeList & n )

Copy constructor.

### QDomNodeList::~QDomNodeList () `[virtual]`

Destructor.

### uint QDomNodeList::count () const

Returns the number of nodes in the list.

This function is the same as length().

### QDomNode QDomNodeList::item ( int index ) const `[virtual]`

Returns the node at position index.

If index is negative or if index >= length() then a null node is returned (i.e. a node for which QDomNode::isNull() returns TRUE).

### uint QDomNodeList::length () const `[virtual]`

Returns the number of nodes in the list.

This function is the same as count().

### bool QDomNodeList::operator!= ( const QDomNodeList & n ) const

Returns TRUE if both lists are not equal, otherwise FALSE.

### QDomNodeList& QDomNodeList::operator= ( const QDomNodeList & n )

Assigns another node list to this object.

### bool QDomNodeList::operator== ( const QDomNodeList & n ) const

Returns TRUE if both lists are equal, otherwise FALSE.

### QDomNodeList::QDomNodeList ( QDOM_NodeListPrivate * p )

For internal use only.
