Use a Counter Inside a For-Each Loop to Track the Number of Loop Iterations

You can use a counter inside a for-each loop to track the number of iterations processed by the loop. This task can be achieved with an xsl:variable through direct edit of the XSLT code.

For example:

• Use the count() and position() XPath functions.
  • The count(location path to the element) returns the number of instances for the node-set (for the element).
  • Within an <xsl:for-each> loop, the position() function returns the iteration number.
• The XSL code snippet for the payload looks as follows:
  
  
  
  
• The pseudo XSL code snippet looks as follows:

• The output looks as follows:
