XML DOM - DocumentType notations Attribute


Hello folks! welcome back to a new edition of our tutorial on XML DOM. In this tutorial, we are going to be studying about the XML DOM DocumentType notations Attribute.

The DOM DocumentType notations attribute contains the notations declared in the DTD.

Syntax

The following below is the syntax to use the DocumentType notations Attribute -

documentObj.doctype.notations

Example

Following are the notation.xml contents -

<?xml version = "1.0"?>
<!DOCTYPE address [
   <!ELEMENT address (#PCDATA)>
   <!NOTATION name PUBLIC "Kennedy">
   <!ATTLIST address category NOTATION (name) #REQUIRED>
]>

<address name = "Kennedy">Hello world!!!!!!</address>


The following example illustrates the usage of the DocumentType notations attribute -

<!DOCTYPE html>
   <head>
      <script>
         function loadXMLDoc(filename) {
            if (window.XMLHttpRequest) {
               xhttp = new XMLHttpRequest();
            } else // code for IE5 and IE6 {
               xhttp = new ActiveXObject("Microsoft.XMLHTTP");
            }
            xhttp.open("GET",filename,false);
            xhttp.send();
            return xhttp.responseXML;
         }
      </script>
   </head>
   <body>
      <script>
         xmlDoc = loadXMLDoc("/dom/notation.xml");
         var notations = xmlDoc.doctype.notations;
         document.write("notations: "+notations);
         document.write("Item "+notations.getNamedItem('Kennedy'));
      </script>
   </body>
</html>

Output

Save this file as documenttype_notations.html on the web server's path (this file and the notation.xml should be on the same path in your server). This is going to give us the following output below -

notations: undefined
