示例

此示例通过迭代每个学生创建一个<student>元素列表及其属性rollno，及子素：<firstname>，<lastname>，<nickname>和<marks>。在这里，我们创建了两个xsl样式表，其中文件：students_imports.xsl 样式表中导入了文件：students.xsl，students.xml 链接到students_imports.xsl。

文件：students.xml -

<?xml version = "1.0"?> 
<?xml-stylesheet type = "text/xsl" href = "students_imports.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>学生信息列表</h2> 
            <table border = "1"> 
               <tr bgcolor = "#12aa32"> 
                  <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>

文件：students_imports.xsl -

<?xml version = "1.0" encoding = "UTF-8"?> 
<xsl:stylesheet version = "1.0" 
   xmlns:xsl = "http://www.w3.org/1999/XSL/Transform">  
   <xsl:import href = "students.xsl"/>  
   <xsl:template match = "/"> 
      <xsl:apply-imports/> 
   </xsl:template>  
</xsl:stylesheet>

在浏览器中打上面文件：student.xml，效果如下所示 -
