Demo Example

此示例通过迭代每个学生来创建带其属性 rollno 及其子属性 <firstname>、<lastname>、<nickname> 和 <marks> 的 <student> 元素列表。此处，我们创建了两个 xsl 样式表，其中 students_imports.xsl 样式表导入 students.xsl，students.xml 链接至 students_imports.xsl。

This example creates a list of <student> element with its attribute rollno and its child <firstname>, <lastname>, <nickname>, and <marks> by iterating over each student. Here we have created two xsl stylesheets where students_imports.xsl stylesheet imports students.xsl and students.xml is linked to students_imports.xsl.

students.xml

students.xml

<?xml version = "1.0"?>
<?xml-stylesheet type = "text/xsl" href = "students_imports.xsl"?>
<class>
   <student rollno = "393">
      <firstname>Dinkar</firstname>
      <lastname>Kad</lastname>
      <nickname>Dinkar</nickname>
      <marks>85</marks>
   </student>
   <student rollno = "493">
      <firstname>Vaneet</firstname>
      <lastname>Gupta</lastname>
      <nickname>Vinni</nickname>
      <marks>95</marks>
   </student>
   <student rollno = "593">
      <firstname>Jasvir</firstname>
      <lastname>Singh</lastname>
      <nickname>Jazz</nickname>
      <marks>90</marks>
   </student>
</class>

students.xsl

students.xsl

      <html>
         <body>
            <h2>Students</h2>
            <table border = "1">
               <tr bgcolor = "#9acd32">
                  <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 = "marks"/></td>
                  </tr>
               </xsl:for-each>
            </table>
         </body>
      </html>
   </xsl:template>
</xsl:stylesheet>

students_imports.xsl

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>

Output
