Problem with printing the strings

hello all,

I am novice to shell scripting and need your help guys.I have a file called myfile.txt and its contents are shown below :
Code:
<project name="device/samsung/crespo" revision="c932ac3b9f8a53a5c433dc7d3cfa2fb5d45a7eb9"/>
  <project name="device/samsung/crespo4g" revision="045aa104f257fdf0946d28e2dcaab549d3bbeaa9"/>
  <project name="device/samsung/maguro" revision="185f51cd2d009e45ae7aa7d8c5ee2de0bda90d33"/>
  <project name="platform/packages/wallpapers/MusicVisualization" path="packages/wallpapers/MusicVisualization" revision="576359ce60d2e0ef8205737570c647c29e3fe922"/>
  <project name="platform/packages/wallpapers/NoiseField" path="packages/wallpapers/NoiseField" revision="4154cea31097a003bdceb9e50f4d69e3ec50e223"/>
  <project name="platform/packages/wallpapers/PhaseBeam" path="packages/wallpapers/PhaseBeam" revision="5cc9b223bc9aa7c45bbb995ab1648286f8d04bbe"/>

Now I want the expected out in different file.You can name this file as output.txt
Output should look like this :

Code:
project device/samsung/crespo c932ac3b9f8a53a5c433dc7d3cfa2fb5d45a7eb9
project device/samsung/crespo4g 045aa104f257fdf0946d28e2dcaab549d3bbeaa9
project device/samsung/maguro
185f51cd2d009e45ae7aa7d8c5ee2de0bda90d33
project packages/wallpapers/MusicVisualization 576359ce60d2e0ef8205737570c647c29e3fe922
project packages/wallpapers/NoiseField 4154cea31097a003bdceb9e50f4d69e3ec50e223
project packages/wallpapers/PhaseBeam 5cc9b223bc9aa7c45bbb995ab1648286f8d04bbe


So far I could do only this :

Code:
awk -F'"' '{print $4"\n" $6"\n"}' myfile.txt >output.txt

But I am not getting the output which is shown above.Let me know how can I do this using a shell script.Should I use if then else or while or should I use grep or find.Let me know.I am messed up with this.

Thank you.

RAKE(1) 						 Ruby Programmers Reference Guide						   RAKE(1)

NAME
rake -- Ruby Make SYNOPSIS
rake [--f Rakefile] [--version] [-CGNPgnqstv] [-D [PATTERN]] [-E CODE] [-I LIBDIR] [-R RAKELIBDIR] [-T [PATTERN]] [-e CODE] [-p CODE] [-r MODULE] [--rules] [variable=value] target ... DESCRIPTION
Rake is a simple ruby(1) build program with capabilities similar to the regular make(1) command. Rake has the following features: o Rakefiles (Rake's version of Makefiles) are completely defined in standard Ruby syntax. No XML files to edit. No quirky Makefile syntax to worry about (is that a tab or a space?). o Users can specify tasks with prerequisites. o Rake supports rule patterns to synthesize implicit tasks. o Flexible FileLists that act like arrays but know about manipulating file names and paths. o A library of prepackaged tasks to make building rakefiles easier. OPTIONS
--version Display the program version. -C --classic-namespace Put Task and FileTask in the top level namespace -D [PATTERN] --describe [PATTERN] Describe the tasks (matching optional PATTERN), then exit. -E CODE --execute-continue CODE Execute some Ruby code, then continue with normal task processing. -G --no-system --nosystem Use standard project Rakefile search paths, ignore system wide rakefiles. -I LIBDIR --libdir LIBDIR Include LIBDIR in the search path for required modules. -N --no-search --nosearch Do not search parent directories for the Rakefile. -P --prereqs Display the tasks and dependencies, then exit. -R RAKELIBDIR --rakelib RAKELIBDIR --rakelibdir RAKELIBDIR Auto-import any .rake files in RAKELIBDIR. (default is rakelib ) -T [PATTERN] --tasks [PATTERN] Display the tasks (matching optional PATTERN) with descriptions, then exit. -e CODE --execute CODE Execute some Ruby code and exit. -f FILE --rakefile FILE Use FILE as the rakefile. -h --help Prints a summary of options. -g --system Using system wide (global) rakefiles (usually ~/.rake/*.rake ). -n --dry-run Do a dry run without executing actions. -p CODE --execute-print CODE Execute some Ruby code, print the result, then exit. -q --quiet Do not log messages to standard output. -r MODULE --require MODULE Require MODULE before executing rakefile. -s --silent Like --quiet, but also suppresses the 'in directory' announcement. -t --trace Turn on invoke/execute tracing, enable full backtrace. -v --verbose Log message to standard output (default). --rules Trace the rules resolution.
