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.
See also QDomNode::childNodes() and QDomDocument::elementsByTagName().
Member Function Documentation
QDomNodeList::QDomNodeList()
Creates an empty node list.
QDomNodeList::QDomNodeList(const QDomNodeList &n)
Constructs a copy of n.
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 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
This function is provided for Qt API consistency. It is equivalent to length().
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 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.
int QDomNodeList::size() const
This function is provided for Qt API consistency. It is equivalent to length().
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 &n)
Assigns n to this node list.
bool QDomNodeList::operator==(const QDomNodeList &n) const
Returns true if the node list n and this node list are equal; otherwise returns false.
