Detailed Description¶
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:
entities()
returns a map of all entities described in the DTD.
notations()
returns a map of all notations described in the DTD.
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.
- class PySide6.QtXml.QDomNamedNodeMap¶
PySide6.QtXml.QDomNamedNodeMap(arg__1)
- Parameters
arg__1 –
PySide6.QtXml.QDomNamedNodeMap
Constructs an empty named node map.
Constructs a copy of n
.
- PySide6.QtXml.QDomNamedNodeMap.contains(name)¶
- Parameters
name – str
- Return type
bool
Returns true
if the map contains a node called name
; otherwise returns false
.
Note
This function does not take the presence of namespaces into account. Use namedItemNS()
to test whether the map contains a node with a specific namespace URI and name.
- PySide6.QtXml.QDomNamedNodeMap.count()¶
- Return type
int
This function is provided for Qt API consistency. It is equivalent to length()
.
- PySide6.QtXml.QDomNamedNodeMap.isEmpty()¶
- Return type
bool
Returns true
if the map is empty; otherwise returns false
. This function is provided for Qt API consistency.
- PySide6.QtXml.QDomNamedNodeMap.item(index)¶
- Parameters
index – int
- Return type
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.

- PySide6.QtXml.QDomNamedNodeMap.length()¶
- Return type
int
Returns the number of nodes in the map.
See also
- PySide6.QtXml.QDomNamedNodeMap.namedItem(name)¶
- Parameters
name – str
- Return type
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 nodeName()
.
See also
- PySide6.QtXml.QDomNamedNodeMap.namedItemNS(nsURI, localName)¶
- Parameters
nsURI – str
localName – str
- Return type
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.

- PySide6.QtXml.QDomNamedNodeMap.__ne__(arg__1)¶
- Parameters
arg__1 –
PySide6.QtXml.QDomNamedNodeMap
- Return type
bool
Returns true
if n
and this named node map are not equal; otherwise returns false
.
- PySide6.QtXml.QDomNamedNodeMap.__eq__(arg__1)¶
- Parameters
arg__1 –
PySide6.QtXml.QDomNamedNodeMap
- Return type
bool
Returns true
if n
and this named node map are equal; otherwise returns false
.
- PySide6.QtXml.QDomNamedNodeMap.removeNamedItem(name)¶
- Parameters
name – str
- Return type
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
.
See also
- PySide6.QtXml.QDomNamedNodeMap.removeNamedItemNS(nsURI, localName)¶
- Parameters
nsURI – str
localName – str
- Return type
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
.
- PySide6.QtXml.QDomNamedNodeMap.setNamedItem(newNode)¶
- Parameters
newNode –
PySide6.QtXml.QDomNode
- Return type
Inserts the node newNode
into the named node map. The name used by the map is the node name of newNode
as returned by 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.
See also
- PySide6.QtXml.QDomNamedNodeMap.setNamedItemNS(newNode)¶
- Parameters
newNode –
PySide6.QtXml.QDomNode
- Return type
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.
- PySide6.QtXml.QDomNamedNodeMap.size()¶
- Return type
int
This function is provided for Qt API consistency. It is equivalent to length()
.
