I want to change the alt= attribute of an image during translation. This is my Lua filter: *function Image(elem) nelem = elem:clone() nelem.attributes.alt = 'image' return nelemend* It doesn't work, though. With HTML like See image: foobar

I get an AST like this [ Plain [ Str "See" , Space , Str "image:" , Space , Image ( "" , [] , [ ( "alt" , "image" ) ] ) [ Str "foobar" ] ( "foo.jpg" , "" ) ] ] I'm not sure how to interprete the Image part, though. The Markdown output is: See image: ![foobar](foo.jpg){alt="image"} which shows that the original alt text is retained, and the intended replacement text is just added as if an arbitrary attribute. What is wrong with my filter? Thanks, T. -- You received this message because you are subscribed to the Google Groups "pandoc-discuss" group.
