XPath - Relative Path

Location path specifies the location of node in XML document. This path can be absolute or relative. If location path starts with the node that we've selected then it is a relative path.

Following are few examples locating the elements using relative path.

firstname − select firstname related to student nodes.

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

Example

In this example, we've created a sample XML document students.xml and its stylesheet document students.xsl which uses the XPath expressions.

Following is the sample XML used.

students.xml

<?xml version = "1.0"?>
<?xml-stylesheet type = "text/xsl" href = "students.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

<?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 Students. </h3>
            <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 = "nickname"/></td>
                     <td><xsl:value-of select = "marks"/></td>		 
                  </tr>
               </xsl:for-each>
            </table> 
         </body>
      </html>
   </xsl:template>
</xsl:stylesheet>
