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 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
