This parser is useful for simple pipelines where the mime-type is sufficient to determine how to parse a blob. To use, configure handlers based on mime-types and pass them to the initializer. Example: .. code-block:: python from langchain_community.document_loaders.parsers.generic import MimeTypeBasedParser parser = MimeTypeBasedParser( handlers={ "application/pdf": ..., }, fallback_parser=..., ) N)fallback_parser)handlersr returncCs||_||_dS)aDefine a parser that uses mime-types to determine how to parse a blob. Args: handlers: A mapping from mime-types to functions that take a blob, parse it and return a document. fallback_parser: A fallback_parser parser to use if the mime-type is not found in the handlers. If provided, this parser will be used to parse blobs with all mime-types not found in the handlers. If not provided, a ValueError will be raised if the mime-type is not found in the handlers.
