XML DOM - Notation Object systemId 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 Notation Object systemId Attribute.

The systemId attribute is used to return the system identifier of a Notation, or Null if no system identifier is specified.


The following below is the syntax to use the systemId Attribute -

var sysid = document.doctype.systemId;


Following are the notation.xml contents -

<?xml version = "1.0" encoding = "UTF-8" standalone = "no"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

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

The following example illustrates the usage of the XML DOM systemId 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/notation_xhtml.xml");
         document.write("The systemId asscoiated with the notation is:"+ xmlDoc.doctype.systemId);


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

The systemId asscoiated with the notation is:http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd
