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 Entity Object systemId Attribute.
The Entity Object systemId attribute is used to return the system identifier of the entity associated or returns null.
The Entity Object systemId attribute is used to return the system identifier of the entity associated or returns null.
Syntax
The following below is the syntax to use the XML DOM Entity Object systemId Attribute -
document.doctype.systemId;
Example
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"> <address id = "firstelement"> <name>Kennedy Nkpara</name > <company>WebDesignTutorialz</company> <phone>(011) 123-4567</phone> </address>
The following example illustrates the usage of the Entity Object systemId attribute -
<!DOCTYPE html> <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_xhtml.xml"); document.write("<b>SystemId :</b> "+xmlDoc.doctype.systemId); </script> </body> </html>
Output
Save this file as entity_systemId.html on the server's path (this file and the notation.xml should be on the same path in your server). This is going to give us the following output below -
SystemId : http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd
