Help me out on Removing the blankspaces from a textarea

Hi All

I have a problem in removing the blank spaces from the textarea in a  .xsl file.

Problem description:
Have to replace the @@@ and with a new line char ('\n')  in the textarea, I 
have used regEx ( JavaScript regular Expression) 
to replace the @@@ characters with a new line ('\n'),But I have noticed that a 
blank space gets appended at the end of the each line
and hence makes the document unreadable.
---------------------------------------------------------------------------------------------------
----Original String (that comes from the Server) before display in to the 
textarea in .xsl file---

.hello
.abcd
@@@E X A M P L E:2^
@@@%description%
@@@.notvoidksdfd@@@%description%||%price% %taxes:r2%
@@@
@@@
@@@.notvoided,voidstatus=VOID,oad=regularasdfasdfa2^
@@@E X A M P L E
@@@.regularjsjs
@@@EXAMPLE CHANGE
@@@
@@@ E X A M P L E
@@@%EXAMPLE DISCOUNTdescription
@@@
@@@.regularline EXAMPLE DISCOUNT
@@@EXAMPLE DISCOUNT
@@@%EXAMPLE DISCOUNT description
---------------------------------------------------------------------------------------------------

At the end of each line an extra space gets added when I save the document and 
hence makes the document unreadable.

Can anyone provide me with a solution to replace @@@ chars in the String before 
displaying into the textarea?

Thanks for any help in advance
