XSLT <xsl:for-each> Element

The XSLT <xsl:for-each> element is used to apply a template repeatedly for each node.

snippet
<xsl:for-each
   select = Expression>  
</xsl:for-each>

Parameter explanation

Select: XPath Expression to be evaluated in current context to determine the set of nodes to be iterated.

XSLT Element Example

Let's take an example to creates a table of <employee> element with its attribute "id" and its child <firstname>,<lastname><nickname> and <salary> by iterating over each employee.

Employee.xml

snippet
<?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>

Employee.xsl

snippet
<?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 
                  <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> 
</xsl:stylesheet>

Output:

XSLT Xsl for each element 1
