Using SimpleWebPageReader

If you’re opening this Notebook on colab, you will probably need to install LlamaIndex 🦙.

!pip install llama-index

from llama_index import SummaryIndex
from llama_index.readers import SimpleWebPageReader
from IPython.display import Markdown, display
import os

# NOTE: the html_to_text=True option requires html2text to be installed

documents = SimpleWebPageReader(html_to_text=True).load_data(
    ["http://paulgraham.com/worked.html"]
)

documents[0]

index = SummaryIndex.from_documents(documents)

# set Logging to DEBUG for more detailed outputs
query_engine = index.as_query_engine()
response = query_engine.query("What did the author do growing up?")

display(Markdown(f"<b>{response}</b>"))

Using TrafilaturaWebReader

from llama_index.readers import TrafilaturaWebReader

documents = TrafilaturaWebReader().load_data(
    ["http://paulgraham.com/worked.html"]
)

index = SummaryIndex.from_documents(documents)

# set Logging to DEBUG for more detailed outputs
query_engine = index.as_query_engine()
response = query_engine.query("What did the author do growing up?")

display(Markdown(f"<b>{response}</b>"))

Using RssReader

from llama_index import SummaryIndex
from llama_index.readers import RssReader

documents = RssReader().load_data(
    ["https://rss.nytimes.com/services/xml/rss/nyt/HomePage.xml"]
)

index = SummaryIndex.from_documents(documents)

# set Logging to DEBUG for more detailed outputs
query_engine = index.as_query_engine()
response = query_engine.query("What happened in the news today?")
