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.


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


Return Value

This method returns a NamedNodeMap object containing the general entities.


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)>

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

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

<!DOCTYPE html>
         function loadXMLDoc(filename) {
            if (window.XMLHttpRequest) {
               xhttp = new XMLHttpRequest();
            } else // code for IE5 and IE6 {
               xhttp = new ActiveXObject("Microsoft.XMLHTTP");
            return xhttp.responseXML;
         xmlDoc = loadXMLDoc("/dom/address_internal_dtd.xml");

         x = xmlDoc.doctype.entities;

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

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


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
