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 amatlab.io.xml.dom.Documentobject.

importmatlab.io.xml.dom.*doc = parseString(Parser,'Hello');

Get the elements namedpara.

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

For everyparaelement, get the attribute names and values and save them in the character vectors.

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

Display the attribute names and values stored ins.
