 I am creating a program, yet again.  How this works is, 
 
 a zope factory calls a form, which submits data from a textarea to a DTML

multiple lines. For instance: 
 
 If a person fills out the textarea like so:
 
 First line
 second line
 third line
 
 I want the DTML document to print out: 
 
 First line
 second line
 third line
 
 The only problem is, when the textarea submits to the document, (lets say the 
textarea is called list), it submits it as a dictionary.  That means all the data is 
on a SINGLE STRING.  So the data from the form looks like this. 
 
 dtml-var "REQUEST.form" = 
 {'list': 'first line/015/012second line/015/012third line'}
 
 the /015/012 represent the line breaks.  
 
 Seeing this, i used the replace function in zope, trying to replace the line breaks 
with br, which would be accepted by html.  however, whenever you try and access the 
information in the form as a string...
 
 dtml-var "REQUEST.form['list']" 
 
 it comes out with 
 
 line one line two line three 
 
 All the line breaks dissapear! So there is nothing to replace! Does anyone have any 
ideas how I could solve this problem?  
 
A couple of questions:

- You say that dtml-var "REQUEST.form['list']" returns 
  line one line two line three
  Is that in your browser window, or did you view the source html?

- Does dtml-var "_.string.replace(REQUEST.form['list'], '\015\012',
'br')"  work?

if you're inserting data with a dtml-var you can take advantage of
Zope's formating options one of which happens to be newline_to_br

try
dtml-var "REQUEST.form['list']" fmt=newline_to_br

The line breaks don't disappear, they just don't mean anything in HTML. 
You can still replace them.  You can do dtml-var
"_.string.replace(REQUEST.form['list'], '\n', 'br')" and it should do
what you want.

dtml-var "REQUEST.form['list']" newline_to_br

Is much simpler. :)
Just out of caution, I would not use 'list' as a variable, though.
