DOM - Entity Object Attribute - systemId
The attribute systemId returns the system identifier of the associated entity or returns null.
Syntax
Following is the syntax for the usage of the systemId attribute.
document.doctype.systemId;
Example
notation.xml contents are as below −
<?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>Tanmay Patil</name > <company>TutorialsPoint</company> <phone>(011) 123-4567</phone> </address>
Following example demonstrates the usage of the 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>
Execution
Save this file as entity_systemId.html on the server path (this file and notation.xml should be on the same path in your server). We will get the output as shown below −
SystemId : http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd
