- **Description:** This PR resolves an issue with the `ExperimentalMarkdownSyntaxTextSplitter` class, which retains the internal state across multiple calls to the `split_text` method. This behaviour caused an unintended accumulation of chunks in `self` variables, leading to incorrect outputs when processing multiple Markdown files sequentially. - Modified `libs\text-splitters\langchain_text_splitters\markdown.py` to reset the relevant internal attributes at the start of each `split_text` invocation. This ensures each call processes the input independently. - Added unit tests in `libs\text-splitters\tests\unit_tests\test_text_splitters.py` to verify the fix and ensure the state does not persist across calls. - **Issue:** Fixes [#26440](https://github.com/langchain-ai/langchain/issues/26440). - **Dependencies:** No additional dependencies are introduced with this change. - [x] Unit tests were added to verify the changes. - [x] Updated documentation where necessary. - [x] Ran `make format`, `make lint`, and `make test` to ensure compliance with project standards. --------- Co-authored-by: Angel Chen <angelchen396@gmail.com> Co-authored-by: Chester Curme <chester.curme@gmail.com>
