Hello Friends,
I have a large file that contains several hundred lines like below:
Xmodels node1 node2 D G S S Al=1 X=2 V=2e-6
=? bitval=1 model=bitval20 color=30 
=? coordinates x-val=20 y-val=30 targetDestroyed=yes
=? missionstatus=completed perimeterSecured=yes
=? repeatMission=false newMission=yes
=? ordinance=34!44 countrycode=red
Xmodels node1020 node4300 D G S S Al=12 X=222 V=23e-6
=? bitval=0101 model=bitval28 color=101AFFFB 
=? coordinates x-val=2370 y-val=390 targetDestroyed=no
=? missionstatus=abandoned perimeterSecured=indeterminate
=? repeatMission=false newMission=InexploreStage
=? ordinance=NULL countrycode=purple

+ modeltype=FOEAWE revolve=true
+ mmodellinespeed=3000fps targacquire=automatic
+ manned=optional
+ roundspersecond=13000/s

How can we create an output file that contains the above lines re-arranged as below? 
Xmodels node1 node2 D G S S Al=1 X=2 V=2e-6 =? bitval=1 model=bitval20
+ color=30 =? coordinates x-val=20 y-val=30 targetDestroyed=yes =? mis

Sorry, new to Perl. Thanks in advance for your help.
