HTML

This covers how to load HTML documents into a document format that we can use downstream.

In [1]:

from langchain.document_loaders import UnstructuredHTMLLoader

In [2]:

loader = UnstructuredHTMLLoader("example_data/fake-content.html")

In [3]:

data = loader.load()

In [4]:

data

Out [4]:

[Document(page_content='My First Heading\n\nMy first paragraph.', lookup_str='', metadata={'source': 'example_data/fake-content.html'}, lookup_index=0)]

Loading HTML with BeautifulSoup4

We can also use BeautifulSoup4 to load HTML documents using the BSHTMLLoader. This will extract the text from the HTML into page_content, and the page title as title into metadata.

In [1]:

from langchain.document_loaders import BSHTMLLoader

In [2]:

loader = BSHTMLLoader("example_data/fake-content.html")
data = loader.load()
data

Out [2]:

[Document(page_content='\n\nTest Title\n\n\nMy First Heading\nMy first paragraph.\n\n\n', metadata={'source': 'example_data/fake-content.html', 'title': 'Test Title'})]
