matlab.io.xml.dom.NamedNodeMap Class

Namespace: matlab.io.xml.dom

Set of document nodes with names

Since R2021a

Description

A matlab.io.xml.dom.NamedNodeMap object contains a set of nodes that have names. These methods return a NamedNodeMap object:

getAttributes method of a matlab.io.xml.dom.Document object
getAttributes method of a matlab.io.xml.dom.DocumentFragment object
getAttributes method of a matlab.io.xml.dom.Element object
getEntities method of a matlab.io.xml.dom.DocumentType object
getNotations method of a matlab.io.xml.dom.DocumentType object

The matlab.io.xml.dom.NamedNodeMap class is a handle class.

Public Methods

`getLength`	`count = getLength(thisNodeMap)` returns the number of items in this named node map.
`getNamedItem`	`node = getNamedItem(thisNodeMap,name)` returns the item in this named node map that has the specified name. Specify `name` as a character vector or string scalar.
`getNamedItemNS`	`node = getNamedItemNS(thisNodeMap,namespace,name)` returns the item in this named node map that has the specified name with the prefix specified by `namespace`. Specify `name` and `namespace` as character vectors or string scalars.
`item`	`node = item(thisNodeMap,index)` returns the item specified by `index`, where 0 specifies the first item in the list, 1 specifies the second item, and so on.

Get Names and Values of Attributes of an Element

Open Live Script

This example finds and displays the names and values of the attributes of an element.

Read an XML string into a matlab.io.xml.dom.Document object.

import matlab.io.xml.dom.*
doc = parseString(Parser,'<para Bold="on" Color="red">Hello</para>');

Get the elements named para.

paralist = getElementsByTagName(doc,'para');
m = getLength(paralist)-1;
s = '';

For every para element, get the attribute names and values and save them in the character vector s.

for i = 0:m
    para = item(paralist,i);
    attrlist = getAttributes(para);
    n = getLength(attrlist)-1;
    for j=0:n
        attr = item(attrlist,j);
        s = [s sprintf('%s = %s\n',getNodeName(attr),getNodeValue(attr))];
    end
end

Display the attribute names and values stored in s.

disp(s);

Bold = on
Color = red
