XML DOM - DocumentType entities 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 entities Attribute.

The DocumentType entities attribute returns a NamedNodeMap object that contains the general entities, both External and Internal, declared in the DTD.

Syntax

The following below is the syntax to use the XML DOM DocumentType entities Attribute -

documentObj.doctype.entities

Return Value

This method returns a NamedNodeMap object containing the general entities.

Example

Following are the address_internal_dtd.xml contents -

<?xml version = "1.0" encoding = "UTF-8" standalone = "no"?>
<!DOCTYPE address [
   <!ELEMENT address    (name,company,phone)>
   <!ELEMENT name    (#PCDATA)>
   <!ELEMENT company   (#PCDATA)>
   <!ELEMENT phone (#PCDATA)>
]>

<address>
   <name>Nkpara Kennedy</name >
   <company>WebDesignTutorialz</company>
   <phone>(011) 123-4567</phone>
</address>


The following example illustrates the usage of the DocumentType entities 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/address_internal_dtd.xml");

         x = xmlDoc.doctype.entities;

         document.write("Nodename is: " + xmlDoc.nodeName);
         document.write("<br>");
         document.write(" nodetype is: " + xmlDoc.nodeType + "<br>");

         y = xmlDoc.documentElement;
         document.write("Nodename is: " + y.nodeName);
         document.write("<br>");
         document.write(" nodetype is: " + y.nodeType + "<br>");
      </script>
   </body>
</html>

Output

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

Nodename is: #document
nodetype is: 9
Nodename is: address
nodetype is: 1
