Try replacing all <tokens> with spaces and then passing through awk:

sed 's/\(<[^>]*>\)/ /g;'

Now you will get:

      Events in   95     Events/sec   0     Messages out   95     Messages/sec

With a little change, you can change the </TRs> into newlines, making it even easier for awk:

 sed 's/\(<\/TR>\)/\n/g; s/\(<[^>]*>\)/ /g;'

Now you get:

  Events in   95
  Events/sec   0
  Messages out   95
  Messages/sec

Now you can pipe through awk:

<above sed command> | awk '/Messages out/ { print $NF }'

will always print the last field on a line matching "Messages out".
