XPath通配符示例

让我们以一个示例为例, 通过遍历每个员工来创建一个<employee>元素及其详细信息的表。

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">

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>
             <xsl:apply-templates select = "class/*" />
          </body>
       </html>
    </xsl:template>
    <xsl:template match = "class/*">
      <xsl:apply-templates select = "@id" />
       <xsl:apply-templates select = "firstname" />
       <xsl:apply-templates select = "lastname" />
       <xsl:apply-templates select = "nickname" />
       <xsl:apply-templates select = "salary" />
       <br />
    </xsl:template>
    <xsl:template match = "@id">
       <span style = "font-size = 22px;">
          <xsl:value-of select = "." />
       </span>
       <br />
    </xsl:template>
    <xsl:template match = "firstname">
      First Name: <span style = "color:blue;">
          <xsl:value-of select = "." />
       </span>
       <br />
    </xsl:template>
    <xsl:template match = "lastname">
      Last Name: <span style = "color:green;">
          <xsl:value-of select = "." />
       </span>
       <br />
    </xsl:template>
    <xsl:template match = "nickname">
      Nick Name: <span style = "color:red;">
          <xsl:value-of select = "." />
       </span>
       <br />
