hi Janis,
Ops,sorry for top-post :)
Your solution,it's much better than the first one.
>>Your data format makes a solution somewhat ugly (see missing space after
t=
he sentence in " works.This ").
I change the data format, have a space:
#cat file
I went fishing for some sea <bass> .
The <bass> part of the song is very moving .
he proposed an elaborate <program> of public works . This information
was taken from the magazine.
the <program> required several hundred lines of code .
The only problem is: is printing after the "."
"proposed elaborate program public works This"
and should said:
"proposed elaborate program public works"
Thanks very much,really
-ric
