Evernote 集成

# 解析 EverNote 笔记需要 lxml 和 html2text
pip install -qU  lxml
pip install -qU  html2text

from langchain_community.document_loaders import EverNoteLoader

# 默认情况下，所有笔记合并为一个 Document
loader = EverNoteLoader("example_data/testing.enex")
loader.load()

[Document(page_content='testing this\n\nwhat happens?\n\nto the world?**Jan - March 2022**', metadata={'source': 'example_data/testing.enex'})]

# 为每条笔记返回一个 Document 通常更有用
loader = EverNoteLoader("example_data/testing.enex", load_single_document=False)
loader.load()
