iReport Header

[ahmy_1]

Hi, I'm new to iReport and i was informed that i can create a subreport in my report as a header so i wouldn't have to create the same header over and over again in other reports. But that said there is another way to just write a simple program/script that would insert xml tags/update jrxml files intead of doing the above because it's faster to render than using subreports. So my question is can some one give a xml example to show me how it this works?
