RST

A reStructured Text (RST) file is a file format for textual data used primarily in the Python programming language community for technical documentation.

UnstructuredRSTLoader

You can load data from RST files with UnstructuredRSTLoader using the following workflow.

from langchain_community.document_loaders import UnstructuredRSTLoader

loader = UnstructuredRSTLoader(file_path="example_data/README.rst", mode="elements")
docs = loader.load()

print(docs[0])

page_content='Example Docs' metadata={'source': 'example_data/README.rst', 'filename': 'README.rst', 'file_directory': 'example_data', 'filetype': 'text/x-rst', 'page_number': 1, 'category': 'Title'}
