QDomNodeList Class ReferenceThe QDomNodeList class is a list of QDomNode objects. More... #include <QDomNodeList> Note: All functions in this class are reentrant. Public Functions
Detailed DescriptionThe 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 DocumentationQDomNodeList::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 ) constThis 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 () constThis function is provided for Qt API consistency. It is equivalent to length(). bool QDomNodeList::isEmpty () constReturns true if the list contains no items; otherwise returns false. This function is provided for Qt API consistency. QDomNode QDomNodeList::item ( int index ) constReturns 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(). uint QDomNodeList::length () constReturns the number of nodes in the list. int QDomNodeList::size () constThis function is provided for Qt API consistency. It is equivalent to length(). bool QDomNodeList::operator!= ( const QDomNodeList & n ) constReturns 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 ) constReturns true if the node list n and this node list are equal; otherwise returns false.
