Filter unwanted lines

Hi All,

I have the below input and i only want to filter out some un-wanted info from here. Expected output is below. Can somebody help ?

The catch is that i want to grep those lines with term "k=" and lines with term "**" as the 1st column and "07" as the last column. And the number of unwanted lines in between the wanted lines are random. On top of that, the number of field of the wanted lines are also random.
Expected output shown below.


Input:
aaa k= aaaa
dddd
dddd
bbb k= cccc
zzz
zzz
zzzzz
ggg k= pppp
vvvvvv
vvv
v
vvvvv
vvvvvv
** XXXXX ZZZ VVV 07
** ccc kkk lll
** ggg lll ppp
** hhh iii kkk
xxxxxx
mmm k= qqqq
xxxxx
ddd
eee k= yyyy
ffff
ff
rrr k= vvvv
ttt
gggggg
zzzzz

Expected Output:
aaa k= aaaa
bbb k= cccc
ggg k= pppp
** XXXXX ZZZ VVV 07
mmm k= qqqq
eee k= yyyy
rrr k= vvvv

set_color(1)							       fish							      set_color(1)

NAME
set_color - set_color - set the terminal color set_color - set the terminal color Synopsis set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR] Description Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple, cyan, white and normal. o -b, --background Set the background color o -c, --print-colors Prints a list of all valid color names o -h, --help Display help message and exit o -o, --bold Set bold or extra bright mode o -u, --underline Set underlined mode o -v, --version Display version and exit Calling set_color normal will set the terminal color to whatever is the default color of the terminal. Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey font color, while set_color --bold white will result in a white font color. Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator. set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of ncurses and recompile fish against it in order to fix this issue. Version 1.23.1 Sun Jan 8 2012 set_color(1)
