Hello 👋

[lexbor\_erl](https://github.com/f34nk/lexbor_erl/tree/main) provides safe, fast HTML parsing, CSS selector querying, DOM manipulation, and streaming parser capabilities for Erlang applications. It wraps the high-performance [Lexbor C library](https://github.com/lexbor/lexbor) using a port-based worker pool architecture for isolation, safety, and parallel processing.

Some years ago, I already implemented an Elixir binding [ModestEx](https://github.com/f34nk/modest_ex) for the Lexbor predecessor [Modest](https://github.com/lexborisov/Modest). Now, that lexbor\_erl is available, [ModestEx is finally migrated using lexbor\_erl](https://elixirforum.com/t/modestex-pipeable-transformations-on-html-strings-with-css-selectors/12793/19) as dependency.

I hope you find this useful!

Congrats on the release.

While I don’t have any use for it currently, I would like to commend your releasing it as an Erlang library. I wish more Elixir library devs took the time to build using this pattern as while it’s _possible_ to use Elixir libs from Erlang it’s still painful.
