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.

Methods

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.

Examples

Get Names and Values of Attributes of an Element

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
