Trimming output of expect script

I am new to Expect scripts. I have Expect script written in a bash script. The script returns me the statistics I require but along with a lot of other stuff from the terminal. "Is there any way I can get precisely the output of the command only?" I have spent a day searching various forums but didn't had any luck. Any sort of help will be appreciated.

Stats = $(expect -c "  
spawn ssh $Username@$Host  
expect \"password:\"  
send \"$Password\r\"  
expect \"\\\\$\"  
send \"ps -A | grep java\r\"  
expect -re \"$USER.*\"  
send \"logout\"  
")

echo $Stats > someFile.txt

You can turn of logging except for the command output:

expect -c "
  log_user 0
    spawn ssh $Username@$Host  
    expect \"password:\"  
    send \"$Password\r\"  
    expect \"\\\\$\"  
  log_user 1
    send \"ps -A | grep java\r\"  
    expect -re \"$USER.*\"  
    send \"logout\"  
 "
