langchain_community.document_loaders.epub.UnstructuredEPubLoader

class langchain_community.document_loaders.epub.UnstructuredEPubLoader(file_path: Optional[Union[str, List[str], Path, List[Path]]], mode: str = 'single', **unstructured_kwargs: Any)[source]

Load EPub files using Unstructured.

You can run the loader in one of two modes: “single” and “elements”. If you use “single” mode, the document will be returned as a single langchain Document object. If you use “elements” mode, the unstructured library will split the document into elements such as Title and NarrativeText. You can pass in additional unstructured kwargs after mode to apply different unstructured settings.

Examples

from langchain_community.document_loaders import UnstructuredEPubLoader

loader = UnstructuredEPubLoader(

“example.epub”, mode=”elements”, strategy=”fast”,

) docs = loader.load()
