You have already posted a similar question in this topic.

Actually I posted a similar questions, but this time I wanted to know specifically whether there is exactly an Elixir AST to XML code convertor.
NobbZ
How should the resulting XML look like, you didn’t even specify this…
gzah
As normal XML does
No just kidding, there is not a particular format, just showing that it has keywords like defmodule, def, print, IO as library …
A basic form of XML code. However if possible a pretty print diagram for an AST would be much better in this specific case.
kokolegorille
Probably not something already made, but it does not seem impossible with the help of any of these packages.
NobbZ
So
"<?xml foo><ast>#{File.read("foo.ex") |> elem(1)}</ast>"is fine for you?Follows your “specification” of “should be XML and contain the info if there was a defmodule etc”.
gzah
Sorry, is that a command or an output result ?
NobbZ
Thats a string that uses interpolation to insert a given files sourcecode into the string. As its wrapped in tags, its close enough to XML.
You might need to escape, as I realise now…
lucaong
The point is that there is no “normal” XML. You could give an example snippet of how the XML could look like. Choosing which fields you want to expose and how to represent the AST in XML is 100% up to you.
Library wise, one of the packages posted by @kokolegorille will probably work to serialize Elixir data structures into XML, but they will require some serialization logic on your side.

I’d just use the streaming serializer of Erlang’s builtin
:xmerlpackage. It’s extremely performant and the fact that Elixir AST is basically a recursive 3-tuples structure (if I remember correctly) should make it extremely easy.
