soupstars 2.1.0

Declarative web parsers

Soupstars :stew: :star: :boom:

Soupstars makes it fast and easy to build web parsers in Python.

It supports python 3.7+

Quickstart

Install it with pip.

pip install soupstars

Create a new parser using the soupstars command. The create command will use a template parser.

soupstars create -m myparser.py

Parsers are simple python modules.

cat myparser.py

Notice that the only set up required is the special parse decorator and a variable named url for the web page you want to parse.

from soupstars import parse

url = "https://corbettanalytics.com/"

@parse
def h1(soup):
    return soup.h1.text

You can test that the parser functions correctly.

soupstars test -m myparser.py

The output is a json object.

{
    "data": {
        "h1": "Level up your analytics"
    },
    "status": 200,
    "url": "https://corbettanalytics.com/",
    "errors": {}
}
