檔案：students.xml -

<?xml version = "1.0"?>
<?xml-stylesheet type = "text/xsl" href = "students.xsl"?> 
<class> 
   <student rollno = "10010">
      <firstname>Machine</firstname> 
      <lastname>Lee</lastname> 
      <nickname>Machine</nickname> 
      <marks>85</marks>
   </student> 
   <student rollno = "10020"> 
      <firstname>Max</firstname> 
      <lastname>Su</lastname> 
      <nickname>Maxsu</nickname> 
      <marks>95</marks>

   <student rollno = "10030"> 
      <firstname>Yii</firstname> 
      <lastname>Bai</lastname> 
      <nickname>Yiibai</nickname> 
      <marks>90</marks>
