ScrapeGraphAI is a web scraping python library that uses LLM and direct graph logic to create scraping pipelines for websites, documents and XML files. Just say which information you want to extract and the library will do it for you!
The reference page for Scrapegraph-ai is available on the official page of pypy: pypi.
pip install scrapegraphaiyou will also need to install Playwright for javascript-based scraping:
playwright installNote: it is recommended to install the library in a virtual environment to avoid conflicts with other libraries 🐱
Official streamlit demo:
Try it directly on the web using Google Colab:
Follow the procedure on the following link to setup your OpenAI API key: link.
The documentation for ScrapeGraphAI can be found here.
Check out also the docusaurus documentation.
You can use the SmartScraper class to extract information from a website using a prompt.
The SmartScraper class is a direct graph implementation that uses the most common nodes present in a web scraping pipeline. For more information, please see the documentation.
Remember to download the model on Ollama separately!
from scrapegraphai.graphs import SmartScraperGraph
graph_config = {
"llm": {
"model": "ollama/mistral",
"temperature": 0,
"format": "json", # Ollama needs the format to be specified explicitly
"base_url": "http://localhost:11434", # set Ollama URL
},
"embeddings": {
"model": "ollama/nomic-embed-text",
"base_url": "http://localhost:11434", # set Ollama URL
}
}
smart_scraper_graph = SmartScraperGraph(
prompt="List me all the articles",
# also accepts a string with the already downloaded HTML code
source="https://perinim.github.io/projects",
config=graph_config
)
result = smart_scraper_graph.run()
print(result)Note: before using the local model remember to create the docker container!
docker-compose up -d
docker exec -it ollama ollama pull stablelm-zephyr
You can use which models available on Ollama or your own model instead of stablelm-zephyr

print(result)The output for all 3 the cases will be a dictionary with the extracted information, for example:
