XSLT元素示例

让我们以一个示例为例, 通过遍历每个员工来创建一个具有其属性” id”及其子级<firstname>, <lastname> <nickname>和<salary>的<employee>元素表。

employee.xml

<?xml version = "1.0"?>
<?xml-stylesheet type = "text/xsl" href = "employee.xsl"?> 
<class> 
   <employee id = "001">
      <firstname>Aryan</firstname> 
      <lastname>Gupta</lastname> 
      <nickname>Raju</nickname> 
      <salary>30000</salary>
   </employee> 
   <employee id = "024"> 
      <firstname>Sara</firstname> 
      <lastname>Khan</lastname> 
      <nickname>Zoya</nickname> 
      <salary>25000</salary>
   </employee> 
   <employee id = "056"> 
      <firstname>Peter</firstname> 
      <lastname>Symon</lastname> 
      <nickname>John</nickname> 
      <salary>10000</salary> 
   </employee> 
</class>

员工.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>Employee</h2> 
            <table border = "1">
               <tr bgcolor = "pink"> 
                  <th>ID</th> 
                  <th>First Name</th> 
                  <th>Last Name</th> 
                  <th>Nick Name</th> 
                  <th>Salary</th> 
               </tr> 
               <!-- for-each processing instruction 
               Looks for each element matching the XPath expression 
               --> 
               <xsl:for-each select="class/employee"> 
                  <tr> 
                     <td> 
                        <!-- value-of processing instruction 
                        process the value of the element matching the XPath expression 
                        --> 
                        <xsl:value-of select = "@id"/> 
                     </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 = "salary"/></td>   
                  </tr> 
               </xsl:for-each> 
            </table> 
         </body> 
      </html>
   </xsl:template>
