Re: copying of selected attributes

| I'm doing some SGML transformation into HTML and have difficulties to 
| accomplish selective attribute copying, even after I spent some time 
| trying (yet not succeeding) to understand the (copy-attributes) 
| function. (list, cons, car and cdr startet to loop in my brain.)
| Here is the problem:
| The source DTD defines a TABLE element with almost the same attlist 
| like the target DTD (HTML). All attributes are implied and the 
| sources additional ID-attribute (optional) has to be transformed 
| into an <A>-element with respective NAME-attribute. 
| So, all but the ID-attribute have to be copied to the target TABLE-
| element. 

I tend to do this with append:

attributes: (append 
              (if (attribute-string "ALIGN")
                  (list (list "ALIGN" (attribute-string "ALIGN")))
                  '())
              (if ...))

                                        Cheers,
                                          norm
