XPath相对路径

如果路径以我们选择的节点开始, 则称为相对路径。

请参阅此语法, 该语法指定使用到雇员节点的相对路径来定位元素。

<p><xsl:value-of select = "firstname"/></p>

XPath相对路径示例

让我们举一个使用绝对路径定位元素的示例。创建一个使用XPath表达式的XML文档employee.xml及其样式表文档employee.xsl。

employee.xml

<?xml version = "1.0"?>
<?xml-stylesheet type = "text/xsl" href = "employee.xsl"?>
<class>
   <employee id = "001">
     <firstname>Abhiram</firstname>
      <lastname>Kushwaha</lastname>
      <nickname>Manoj</nickname>
      <salary>15000</salary>
   </employee>
   <employee id = "002">
      <firstname>Akash</firstname>
      <lastname>Singh</lastname>
      <nickname>Bunty</nickname>
      <salary>25000</salary>
   </employee>
    <employee id = "003">
      <firstname>Brijesh</firstname>
      <lastname>Kaushik</lastname>
      <nickname>Ballu</nickname>
      <salary>20000</salary>
   </employee>
    <employee id = "004">
      <firstname>Zoya</firstname>
      <lastname>Mansoori</lastname>
      <nickname>Sonam</nickname>
      <salary>30000</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>
             <h3>Details of each Employee.  </h3>
             <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>						
                <xsl:for-each select = "/class/employee">
                   <tr>
                      <td><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>
 </xsl:stylesheet>
