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.

You can get a particular node from the list with item(). The number of items in the list is returned by length().

For further information about the Document Object Model see Level 1 and Level 2 Core. For a more general introduction of the DOM implementation see the QDomDocument documentation.

Constructor & Destructor Documentation

QDomNodeList::QDomNodeList ( )

Creates an empty node list.

QDomNodeList::QDomNodeList ( const QDomNodeList &  other)

Copy constructs a new QDomNodeList from other.

QDomNodeList::~QDomNodeList ( )

Destroys the object and frees its resources.

Method Documentation

QDomNode QDomNodeList::at ( int  index) const
inline

This function is provided for API consistency. It is equivalent to item().

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

int QDomNodeList::count ( ) const
inline

This function is provided for API consistency. It is equivalent to length().

bool QDomNodeList::isEmpty ( ) const
inline

Returns true if the list contains no items, otherwise returns false. This function is provided for API consistency.

QDomNode QDomNodeList::item ( int  index) const

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).

See also
length()
int QDomNodeList::length ( ) const

Returns the number of nodes in the list.

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

Returns true the node list n and this node list are not equal, otherwise returns false.

QDomNodeList & QDomNodeList::operator= ( const QDomNodeList &  other)

Copy assigns from other and returns a reference to this object.

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

Returns true if the node list n and this node list are equal, otherwise returns false.

int QDomNodeList::size ( ) const
inline

This function is provided for API consistency. It is equivalent to length().
