Hi, Salonee.  It has been a little while since I wrote any ErlTL, but
if memory serves, the only way to get rid of whitespace in your output
is to get rid of whitespace in your input.  That is, write the whole
'user' function definition on one line:

<%@ user %><%? {Uid,Name} = Data %><friend>...</friend>

You may also be able to play games with ErlTL comments.  Something like:

<%@ user %><%!
%><%? {Uid,Name} = Data %><%!

but, I don't remember.
