Detailed Description

TheQDomNodeList class is a list ofQDomNode objects.

Lists can be obtained byQDomDocument::elementsByTagName() andQDomNode::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 withitem(). The number of items in the list is returned bylength().

For further information about the Document Object Model seeLevel 1 andLevel 2 Core. For a more general introduction of the DOM implementation see theQDomDocument documentation.

Member Function Documentation

QDomNodeList::QDomNodeList()

Creates an empty node list.

QDomNodeList::QDomNodeList(constQDomNodeList & n)

Constructs a copy ofn.

QDomNodeList::~QDomNodeList()

Destroys the object and frees its resources.

QDomNode QDomNodeList::at(int index) const

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

Ifindex is negative or ifindex >=length() then a null node is returned (i.e. a node for whichQDomNode::isNull() returns true).

int QDomNodeList::count() const

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

bool QDomNodeList::isEmpty() const

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

QDomNode QDomNodeList::item(int index) const

Returns the node at positionindex.

Ifindex is negative or ifindex >=length() then a null node is returned (i.e. a node for whichQDomNode::isNull() returns true).

See alsolength().

uint QDomNodeList::length() const

Returns the number of nodes in the list.

int QDomNodeList::size() const

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

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

Returns true the node listn and this node list are not equal; otherwise returns false.

QDomNodeList & QDomNodeList::operator=(constQDomNodeList & n)

Assignsn to this node list.

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

Returns true if the node listn and this node list are equal; otherwise returns false.
