Needing help with searching and replace in a file (sed?)
Hello,
I'm wondering where I could go to learn how to edit file sections that cross multiple lines. I'm wanting to write scripts that will add Gnome menu entries for all users on a system for scripts I write, etc. I can search an replace simple examples with sed, but this seems more complex.
I am on a 'doz system in a hotel right now so I can't post the actual file, but the Gnome menu entry has a structure similar to this:
Say I need to change the markups for the dasher.desktop file from <Exclude> to <Include> and </Exclude> to </Include>?
What If I wanted to add a new <Include></Include> section for a new .desktop file?
Compounding this is that there is variable whitespace indentation depending on how deep into the structure one needs to go and it would be nice to keep the formatting for readability and a nicer, more polished look.
Basically, what is the technique for finding something, and then modifying something on lines above and/or below it OR finding a section, and then adding something on a line below that section without modifying that line in the process.
I don't mind learning myself, but I need pointed in the right direction. I'm not sure where to start. This seems like a bit of a big job for sed. If someone would want to code an example, I'm up for that too as I can learn from that (hey, learning is fun, right?)

menufile
MENUFILE(5) File Formats Manual MENUFILE(5)NAME
menufile - entry in the Debian menu system
SYNOPSIS
~/.menu/*
/etc/menu/*
/usr/lib/menu/*
/usr/share/menu/*
/usr/share/menu/default/*
DESCRIPTION
Menu files add entries to the Debian menu system. The system administrator can place menu files in /etc/menu/ to override menu files that
packages add to /usr/share/menu/ . The user can place menu files in ~/.menu/ to override all other menu files.
Please read the Debian menu manual available in /usr/share/doc/menu/html for the complete specification of menu files.
The menu files are usually named after the Debian package that contains the programs listed in them. In it, you can list several "menu
entries" that specify a specific item in the menu structure. Each menu entry specifies which packages it depends on; if that package are
not installed, the menu entry will be ignored by update-menus(1). (In a menu entry you can specify pseudo-packages that start with
"local."; update-menus will always use those menu entries). If you wish to remove an item from the menu entirely, make an empty menu file
with the same name as the file you want to override.
Examples
Dosemu could install the following menu file as /usr/share/menu/dosemu:
?package(dosemu):needs="text" section="Applications/Emulators" title="Dosemu" command="dosemu"
?package(dosemu):needs="X11" section="Applications/Emulators" title="Dosemu" command="xdos"
The system administrator wants to override this file to change how dosemu is run, so /etc/menu/dosemu is created:
?package(dosemu):needs="text" section="Applications/Emulators" title="Dosemu" command="dosemu -A"
?package(dosemu):needs="X11" section="Applications/Emulators" title="Dosemu" command="xdos -A"
A user does not want Dosemu to appear in the menus at all, so the user creates an empty file named ~/.menu/dosemu.
FORMAT
A menu file consists of 0 or more lines of the following format:
?package(package-name):var1=value1 var2=value2 ...
needs Specify what kind of environment the program require. This variable must be defined, and should be one of the following:
needs="text"
Program requires a terminal
needs="x11"
Program requires a X server
needs="vc"
Program requires a Linux console (i.e.: svgalib programs)
needs="wm"
The program is a window manager.
needs="fvwmmodule"
The program is a fvwm compatible module.
section
The section in which the menu entry should appear. See MENU LAYOUT for preferred section names.
icon An icon for this menu entry. If no icon is available, just don't define this.
title The title of the program that will appear on the menus. Keep it short. If two menu entries share the same title and section,
the one that best fits the available display will be used. So in the example above with two menu entries that both have the
menu id "title", if X is available, the X11 one will be used; otherwise the text one will be used. Must be defined.
command
The command to be executed when this menu entry is selected.
hints A comma-separated list of hints on how grouping menu entries; see the manual.
MENU LAYOUT
The authoritative list of Debian's menu structure is maintained in the Debian Menu sub-policy document which is part of the Debian Policy
package. The menu structure below is included only for convenience. Please do not put your packages into any other sections.
Use `/' to separate sub-menu names, for example, "Applications/Editors" or "Games/Arcade".

NOTES
If you want to specify an icon or hotkey for a sub-menu (for example, the Editors sub-menu), just use the same syntax but leave the command
empty:
?package(mypackage):needs="X11" section="Applications" icon="icon.xpm" hotkey="E" title="Editors"
Whenever any menu files are changed, you must run update-menus(1)FILES
(Earlier listed files override later files with the same names.)

/etc/menu/*
