i executed an xml file using exec command in perl but after the exec there are some lines in perl to modify that xml file but what it does

the xml file alone is executed and then returns the lines after the exec command is not taken into account !

try using system() instead of exec(). Once you call exec() it exits the perl program and never returns. This is clearly stated in the exec() functions man page. If you need return value from the program use qx// instead of system().
