XPath 绝对路径

17 Mar 2025 | 阅读 2 分钟

有两种位置路径用于指定 XML 文档中节点的位置。这些路径是绝对路径或相对路径。

绝对路径以根节点或 '/' 开头。

/company/employee - 它将选择类根节点中的 employee 节点。

/company/employee/firstname - 它将选择类根节点中 employee 节点的 firstname。

XPath 绝对路径示例

让我们来看一个使用绝对路径定位元素的示例。创建一个 XML 文档 employee.xml 及其样式表文档 employee.xsl，它使用 XPath 表达式。

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>

Employee.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>						
               <tr>
                  <td><xsl:value-of select = "/class/employee[1]/@id"/></td>
                  <td><xsl:value-of select = "/class/employee[1]/firstname"/></td>

                  <td><xsl:value-of select = "/class/employee[1]/salary"/></td>		 
               </tr>					
               <tr>
                  <td><xsl:value-of select = "/class/employee[2]/@id"/></td>
                  <td><xsl:value-of select = "/class/employee[2]/firstname"/></td>
                  <td><xsl:value-of select = "/class/employee[2]/lastname"/></td>

                  <td><xsl:value-of select = "/class/employee[2]/salary"/></td>		 
               </tr>		
                <tr>
                  <td><xsl:value-of select = "/class/employee[3]/@id"/></td>
                  <td><xsl:value-of select = "/class/employee[3]/firstname"/></td>

                  <td><xsl:value-of select = "/class/employee[3]/salary"/></td>		 
               </tr>
