Sorry, I did not described my problem exactly.  My problem is perhaps
that I do not know *which* is the correct type of my variable keywords.
(Sorry, I'm a little bit C-centered where I had to declare each variable.)

I think I post my complete method to clarify:

def manage_addMyFolder(self, id, title='',
                     keywords='',       #### not sure if this is correct but
                                        #### it worked so far
                     createPublic=1,
                     createSelection=1,
                     createHome=1,
                     createUserF=0,
                     REQUEST=None):
    """Add a new MyFolder object with id *id* and
       global keywords *keywords* and author *author*.

    If the 'createPublic' and 'createUserF' parameters are set to any true
    value, an 'index_html' and a 'UserFolder' objects are created respectively
    in the new folder.

    You can specify certain keywords which are inserted into each Document inside
    this folder.
    """
    ob=MyFolder()
    ob.id=str(id)
    ob.title=title
    ob.keywords=keywords   #### this works but I want to remove whitespaces
                           #### and empty lines
#    for kw in keywords:     #### this does not work :-(  see below
#        kw=kw.strip()
#        if kw != '' :
#            ob.keywords = ob.keywords + '\n' + kw
    self._setObject(id, ob)
    ob=self._getOb(id)

    checkPermission=getSecurityManager().checkPermission

    if createUserF:
        if not checkPermission('Add User MyFolders', ob):
            raise 'Unauthorized', (
                  'You are not authorized to add User MyFolders.'
                  )
        ob.manage_addUserFolder()

    if createPublic:
        if not checkPermission('Add Documents, Images, and Files', ob):
            raise 'Unauthorized', (
                  'You are not authorized to add DTML Documents.'
                  )
        ob.manage_addDTMLDocument(id='index.htm', title=ob.id+' main frame')

    if REQUEST is not None:
        return self.manage_main(self, REQUEST, update_menu=1)

The problem obviousely is, that I do not know what Python type is appropriate
to store the *lines* which are obtained in a

  <tr valign="top">
    <th class="form-optional">Keywords<br>(One per line)</th>
    <td><textarea name="keywords:lines" cols="50" rows="10">
    </textarea>
    </td>
  </tr>

textarea and how I should strip the whitespaces and empty lines from it.
a string variable separated by '\n' does not work either as I tested
because if I want to edit them I get:

      Error Type: InError
      Error Value: Strings are not allowed as input to the in tag.

So the question is:  How to strip the whitespace from the keywords correctly.

Thanks for your patience

           Andreas.
