Subject RE: Preserving Line Breaks in <c:out>
Date Wed, 16 Jul 2003 23:57:30 GMT
Thanks Serge. Your suggestion works great with one caveat:

I can't specify delims="\r\n" because those values are used literally.
However, this seems to work:

<% String newline = "\r\n"; pageContext.setAttribute("newline",
newline); %>
<c:forTokens items="${foo}" delims="${newline}" var="foo">

This is close to 1), but use c:forTokens delims="\r\n".  In the loop, 
print each element with whatever <br> you want between them.

It's a bit more content in JSP, but then you don't have to worry about 
leaving some of the content unescaped.  I usually use <pre>.
