DOM - DocumentType Object Attribute - notation


Advertisements


The attribute notations containing the notations declared in the DTD.

Example

notation.xml contents are as below −

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

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

Following example demonstrates the usage of the 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('Tanmay'));
      </script>
   </body>
</html>
