[Zope] strange script behaviour

[Marie Robichon]

Hi everyone,

I have a script that loops thru' formulator and creates the insert sql 
string (with a view to creating the sqlMethod on the fly).  When I come to 
multicheckbox fields I want enter the selected values into my db column by 
separating them with a semi-colon.  However when I want to do this part of 
the script :

     if field.meta_type=='MultiCheckBoxField':
          sql=sql+"<dtml-in " + field.id + ">\n"
          sql=sql+"<dtml-var sequence-item>;"
          sql=sql+"</dtml-in>,"

the '/' of the </dtml-in> prevents the string from being rendered properly 
and results in the following (and none of the line breaks appear):

....
values (, , , , , , , , , , , , , , , , ;,, ;,, , , , , ;, ;,, , , , , , , 
;,, , , , , )

However if I remove the '<' of the </dtml-in> and leave it '/dtml-in>, the 
string renders  ok:

....
values
(<dtml-sqlvar nom type=string >,
<dtml-in prestataire>
<dtml-var sequence-item>;/dtml-in>,

  I don't understand at all since all I am doing is concatenating strings.

Thanks in advance for your help (full script below)
