Remote Page/File Loader
This loader makes it easy to extract the text from the links available in a webpage URL, and extract the links presents in the page. It's based on RemoteReader (reading single page), that is based on SimpleDirectoryReader (parsing the document if file is a pdf, etc). It is an all-in-one tool for (almost) any group of urls.
You can try with this MIT lecture link, it will be able to extract the syllabus, the PDFs, etc:

Usage
You need to specify the parameter depth to specify how many levels of links you want to extract. For example, if you want to extract the links in the page, and the links in the links in the page, you need to specify depth=2.
from llama_index import download_loader
RemoteDepthReader = download_loader("RemoteDepthReader")
loader = RemoteDepthReader()
documents = loader.load_data(url="https://ocw.mit.edu/courses/5-05-principles-of-inorganic-chemistry-iii-spring-2005/pages/syllabus/")
This loader is designed to be used as a way to load data into LlamaIndex and/or subsequently used as a Tool in a LangChain Agent. See here for examples.
