Returns a modified tree. An action is a function of the form `action(key, value, format, meta)`, where: * `key` is the type of the pandoc object (e.g. 'Str', 'Para') `value` is * the contents of the object (e.g. a string for 'Str', a list of inline elements for 'Para') * `format` is the target output format (as supplied by the `format` argument of `walk`) * `meta` is the document's metadata The return of an action is either: * `None`: this means that the object should remain unchanged * a pandoc object: this will replace the original object * a list of pandoc objects: these will replace the original object; the list is merged with the neighbors of the orignal objects (spliced into the list the original object belongs to); returning an empty list deletes the object tcNcs i|]\}}t||qSr)walk).0r(r))actionr0metarr szwalk..) isinstancelistdictr#r5items)xr7r0r8arrayitemr'zr)r7r0r8rr5gs"     r5cCst|gdS)zALike `toJSONFilters`, but takes a single action as argument.
