Subject: Finding one certain line in a file is easy but how to look for headlines and something just under this certain headline?

Hi,
I'm writing a little script for installing ati-drivers on linux machines but I have a little problem. I need to change the /etc/X11/xorg.conf file for this. This file is built like this (just a cut-out):

Section "InputDevice"
        Identifier      "Generic Keyboard"
        Driver          "kbd"
        Option          "CoreKeyboard"
        Option          "XkbRules"      "xorg"
        Option          "XkbModel"      "pc105"
        Option          "XkbLayout"     "de"
        Option          "XkbOptions"    "lv3:ralt_switch"
EndSection

Section "Device"
        Identifier      "Standardgrafikkarte"
        Driver          "ati"
        BusID           "PCI:1:0:0"
EndSection

Section "Monitor"
        Identifier      "Standardbildschirm"
        Option          "DPMS"
        HorizSync       28-64
        VertRefresh     43-60
EndSection

Section "DRI"
        Mode    0666
EndSection

Section "Extensions"
        Option "Composite" "Disable"
EndSection


Now I need to change the driver value within the Section "Device" from ati|vesa|radeon|nomatterwhat... to fglrx, but how to find it? E.g. IO.foreach('/etc/X11/xorg.conf')  { |line| puts line if line =~ /^Section "Device"/ } finds me the correct section but how to "navigate" now in it? Is iteration at all the answer to this problem?


greets
