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.


Method Documentation

QDomNodeList.__init__ (self)

Creates an empty node list.

QDomNodeList.__init__ (self, QDomNodeList)

Constructs a copy of n.

QDomNode QDomNodeList.at (self, int index)

This function is provided for Qt 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 (self)

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

bool QDomNodeList.isEmpty (self)

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

QDomNode QDomNodeList.item (self, int index)

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 (self)

Returns the number of nodes in the list.

int QDomNodeList.size (self)

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

bool QDomNodeList.__eq__ (self, QDomNodeList)

int QDomNodeList.__len__ (self)

bool QDomNodeList.__ne__ (self, QDomNodeList)
