Introduction

The sum function is used to perform the addition of two or more values, which could be either numerical values or xpath expressions.

Syntax :

• ${ixf:sum(xpathExp1, xpathExp2)}" calculates the sum of the results obtained from evaluating "xpathExp1" and "xpathExp2".
• ${ixf:sum("10",'12','100')}, the result will be 122, which is the sum of the individual results of "10", "12", and "100".
• ${ixf:sum(xpathExp,"10")} the result will be the sum of the result obtained from evaluating "xpathExp" and 10

Note:

Ensure that numerical values are between double quotes (Example: "10") or single quotes (Ex: '22'),

while xpath expressions should remain without any quote enclosures.
