MimeTypeBasedParser#
- class langchain_community.document_loaders.parsers.generic.MimeTypeBasedParser(handlers: Mapping[str, BaseBlobParser], *, fallback_parser: BaseBlobParser | None = None)[source]#
Parser that uses mime-types to parse a blob.
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
from langchain_community.document_loaders.parsers.generic import MimeTypeBasedParser parser = MimeTypeBasedParser( handlers={ "application/pdf": ..., }, fallback_parser=..., )
Define a parser that uses mime-types to determine how to parse a blob.
- Parameters:
handlers (Mapping[str, BaseBlobParser]) – A mapping from mime-types to functions that take a blob, parse it and return a document.
fallback_parser (BaseBlobParser | None) – 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.
Methods
__init__(handlers, *[, fallback_parser])Define a parser that uses mime-types to determine how to parse a blob.
lazy_parse(blob)Load documents from a blob.
parse(blob)Eagerly parse the blob into a document or documents.
- __init__(handlers: Mapping[str, BaseBlobParser], *, fallback_parser: BaseBlobParser | None = None) None[source]#
