示例

此示例通過迭代每個學生創建一個<student>元素的表格,其中包含其屬性rollno及其子素:<firstname><lastname><nickname><marks>

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

文件:students.xsl -

<?xml version = "1.0" encoding = "UTF-8"?> 
   <xsl:stylesheet version = "1.0" 
      xmlns:xsl = "http://www.w3.org/1999/XSL/Transform">
   <xsl:template match = "/"> 
      <html> 
         <body> 
            <h2>學生信息列表</h2> 
            <table border = "1"> 
               <tr bgcolor = "#3498db"> 
                  <th>Roll No</th> 
                  <th>First Name</th> 
                  <th>Last Name</th> 
                  <th>Nick Name</th> 
                  <th>Marks</th> 
               </tr> 

               <xsl:for-each select = "class/student"> 

                  <tr> 
                     <td><xsl:value-of select = "@rollno"/></td> 
                     <td><xsl:value-of select = "firstname"/></td> 
                     <td><xsl:value-of select = "lastname"/></td> 
                     <td><xsl:value-of select = "nickname"/></td> 
                     <td><xsl:value-of select = "marks"/></td> 
                  </tr> 
               </xsl:for-each> 

            </table> 
         </body> 
      </html> 
   </xsl:template>  
</xsl:stylesheet>
