I think this code will do what you want:

    if hasattr(client,ident):
      client.manage_delObjects([ident])
    client.manage_addDTMLDocument(id=ident,file=myfile,title=mytitle3)

you want to check if client has an attribute with the name stored in ident, not 
if ident is anything but an empty string ;-)

cheers,
