The QDomNamedNodeMap class contains a collection of nodes that can be accessed by name.

Note that QDomNamedNodeMap does not inherit from QDomNodeList. QDomNamedNodeMaps do not provide any specific node ordering. Although nodes in a QDomNamedNodeMap may be accessed by an ordinal index, this is simply to allow a convenient enumeration of the contents of a QDomNamedNodeMap, and does not imply that the DOM specifies an ordering of the nodes.
The QDomNamedNodeMap is used in three places: 1 QDomDocumentType::entities() returns a map of all entities described in the DTD. QDomDocumentType::notations() returns a map of all notations described in the DTD. QDomNode::attributes() returns a map of all attributes of an element.
Items in the map are identified by the name which QDomNode::name() returns. Nodes are retrieved using namedItem(), namedItemNS() or item(). New nodes are inserted with setNamedItem() or setNamedItemNS() and removed with removeNamedItem() or removeNamedItemNS(). Use contains() to see if an item with the given name is in the named node map. The number of items is returned by length().
Terminology: in this class we use "item" and "node" interchangeably.
| QDomNamedNodeMap::QDomNamedNodeMap | ( | ) |
Constructs an empty named node map.
| QDomNamedNodeMap::QDomNamedNodeMap | ( | const QDomNamedNodeMap & | n | ) |
Constructs a copy of n.
| QDomNamedNodeMap::~QDomNamedNodeMap | ( | ) |
Destroys the object and frees its resources.
| QDomNamedNodeMap::QDomNamedNodeMap | ( | ) |
| QDomNamedNodeMap::QDomNamedNodeMap | ( | const QDomNamedNodeMap & | ) |
| QDomNamedNodeMap::~QDomNamedNodeMap | ( | ) |
Returns TRUE if the map contains a node called name; otherwise returns FALSE.
| uint QDomNamedNodeMap::count | ( | ) | const [inline] |
Returns the number of nodes in the map.
This function is the same as length().
| uint QDomNamedNodeMap::count | ( | ) | const [inline] |
Retrieves the node at position index.
This can be used to iterate over the map. Note that the nodes in the map are ordered arbitrarily.
| uint QDomNamedNodeMap::length | ( | void | ) | const |
Returns the number of nodes in the map.
| uint QDomNamedNodeMap::length | ( | ) | const |
Returns the node called name.
If the named node map does not contain such a node, a null node is returned. A node's name is the name returned by QDomNode::nodeName().
Returns the node associated with the local name localName and the namespace URI nsURI.
If the map does not contain such a node, a null node is returned.
| bool QDomNamedNodeMap::operator!= | ( | const QDomNamedNodeMap & | n | ) | const |
Returns TRUE if n and this named node map are not equal; otherwise returns FALSE.
| bool QDomNamedNodeMap::operator!= | ( | const QDomNamedNodeMap & | ) | const |
| QDomNamedNodeMap & QDomNamedNodeMap::operator= | ( | const QDomNamedNodeMap & | n | ) |
Assigns n to this named node map.
| QDomNamedNodeMap& QDomNamedNodeMap::operator= | ( | const QDomNamedNodeMap & | ) |
| bool QDomNamedNodeMap::operator== | ( | const QDomNamedNodeMap & | ) | const |
| bool QDomNamedNodeMap::operator== | ( | const QDomNamedNodeMap & | n | ) | const |
Returns TRUE if n and this named node map are equal; otherwise returns FALSE.
Removes the node called name from the map.
The function returns the removed node or a null node if the map did not contain a node called name.
Removes the node with the local name localName and the namespace URI nsURI from the map.
The function returns the removed node or a null node if the map did not contain a node with the local name localName and the namespace URI nsURI.
Inserts the node newNode into the named node map. The name used by the map is the node name of newNode as returned by QDomNode::nodeName().
If the new node replaces an existing node, i.e. the map contains a node with the same name, the replaced node is returned.
Inserts the node newNode in the map. If a node with the same namespace URI and the same local name already exists in the map, it is replaced by newNode. If the new node replaces an existing node, the replaced node is returned.
