Dette er scriptet (JScript), som læser data ved hjælp af DOM og MSXML:

SQLAdminXML = "SQLAdmin.xml";  // XML document with metadata

var objXML = new ActiveXObject( "MSXML2.DOMDocument.6.0" );
objXML.async = false;

try {
	objXML.load( SQLAdminXML );
}
catch( e ) {
	alert( 'ERROR: Could not load the config file "' + SQLAdminXML + '".' );
	objXML = null;
	throw( e );
}

var SQLInstances = objXML.getElementsByTagName( "SQLinstance" );

for(var i = 0; i < SQLInstances.length; i++ ) {
	WScript.Echo( "Windows Server name = " + SQLInstances[i].getElementsByTagName( "winsrvname" )[0].text );
	
	var Shares = SQLInstances[i].getElementsByTagName( "share" );
	for( var j = 0; j < Shares.length; j++ ) {
		WScript.Echo( "Share '" + Shares[j].getElementsByTagName( "sharename" )[0].text + "': " + Shares[j].getElementsByTagName( "sharedesc" )[0].text );
	}
	Shares = null;
}

SQLInstances = null;
objXML = null;
