'How to use loops in JasperReports .jrxml file?
I am using iReport Designer to design the .jrxml file.
How can I use the for loop or if loop in .jrxml file?
Is it possible?
If yes how?

You may wish to use a scriptlet. It's basically a Java class that extends either of the following two classes:
In a scriptlet, you can indicate that a certain piece of code should be executed every time a report event occurs, e.g., report, page, or column initialization.
In a scriptlet, you may use loops. You may access fields, parameters, and variable values. You may also adjust variable values.
There is a chapter on scriptlets in the JasperReports Ultimate Guide.

Well what you can do is create a list of selected fields(which client UI selects) and pass it as a collection to JasperFillManager.fillReport and in the jrxml create a field names _THIS which will represent the value's in the List. And as you want those field to printed in loop, place them in the detail band of the report.
