Scrape HTML automatically

Project description

CI status PyPI version PyPI python version

mlscraper allows you to extract structured data from HTML automatically instead of manually specifying nodes or css selectors. You train it by providing a few examples of your desired output. It will then figure out the extraction rules for you automatically and afterwards you’ll be able to extract data from any new page you provide.

Background Story

Many services for crawling and scraping automation allow you to select data in a browser and get JSON results in return. No need to specify CSS selectors or anything else.

I’ve been wondering for a long time why there’s no Open Source solution that does something like this. So here’s my attempt at creating a python library to enable automatic scraping.

All you have to do is define some examples of scraped data. mlscraper will figure out everything else and return clean data.

How it works

After you’ve defined the data you want to scrape, mlscraper will:

  • find your samples inside the HTML DOM

  • determine which rules/methods to apply for extraction

  • extract the data for you and return it in a dictionary

Getting started

mlscraper is currently short before version 1.0. If you want to check the new release, use pip install --pre mlscraper to test the release candidate. You can also install the latest (unstable) development version of mlscraper via pip install git+https://github.com/lorey/mlscraper#egg=mlscraper, e.g. to check new features or to see if a bug has been fixed already. Please note that until the 1.0 release pip install mlscraper will return an outdated 0.* version. Check the examples directory for usage examples until further documentation arrives.

Development
