|

|
|
|
||
|
|
|
||
|
|
|
||
|
|
The QDomNamedNodeMap class contains a collection of nodes
|
||
|
|
that can be accessed by name.
|
||
|
|
|
||
|
|
<p>
|
||
|
|
|
||
|
|
<p> Note that QDomNamedNodeMap does not inherit from <a href="qdomnodelist.html">QDomNodeList</a>.
|
||
|
|
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.
|
||
|
|
<p> The QDomNamedNodeMap is used in three places:
|
||
|
|
<ol type=1>
|
||
|
|
<li> <a href="qdomdocumenttype.html#entities">QDomDocumentType::entities</a>() returns a map of all entities
|
||
|
|
described in the DTD.
|
||
|
|
<li> <a href="qdomdocumenttype.html#notations">QDomDocumentType::notations</a>() returns a map of all notations
|
||
|
|
described in the DTD.
|
||
|
|
<li> <a href="qdomnode.html#attributes">QDomNode::attributes</a>() returns a map of all attributes of an
|
||
|
|
element.
|
||
|
|
</ol>
|
||
|
|
<p> Items in the map are identified by the name which QDomNode::name()
|
||
|
|
returns. Nodes are retrieved using <a href="#namedItem">namedItem</a>(), <a href="#namedItemNS">namedItemNS</a>() or
|
||
|
|
<a href="#item">item</a>(). New nodes are inserted with <a href="#setNamedItem">setNamedItem</a>() or
|
||
|
|
<a href="#setNamedItemNS">setNamedItemNS</a>() and removed with <a href="#removeNamedItem">removeNamedItem</a>() or
|
||
|
|
<a href="#removeNamedItemNS">removeNamedItemNS</a>(). Use <a href="#contains">contains</a>() to see if an item with the
|
||
|
|
given name is in the named node map. The number of items is
|
||
|
|
returned by <a href="#length">length</a>().
|
||
|
|
<p> Terminology: in this class we use "item" and "node"
|
||
|
|
interchangeably.
|
||
|
|

Inserts the node <em>newNode</em> 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 <em>newNode</em>. If the new node replaces an existing
|
