Today I am gonna write about,how to use summation function in XSL and how to create a cariable and use it in your xsl. Actually,there was a requirement in our project,which was like adding some values of some fields in the input and based upon the sum we required to pass some value to the target system.So, to accomplish this we used sum function, that is available in xslt.
I will be demonstrating it taking one example.Suppose we have some fields that are coming in the input such as A,B,C and we need to add all these values and see whether its sum is greater than zero or less than zero.If the sum is greater than 0, we will pass say "pass" and if its other way around we will pass say "fail" to the target system.I have create a sample BPEL process for this usecase.Process is very simple: it is exposed as webservice and taking input from the client and after doing aforesaid transformation and logic will publish the message in jms Queue.I will just explain the XSL part.
