Build Status

Description

Basic bindings for cheerio. Only includes read-only functionality for now.

Installation

Install cheerio dependency:

$ npm install --save cheerio

Install this package using spago:

  • Add package to your spago.dhall:
...
dependencies = [ ..., "cheerio" ]
...
  • Install packages by running:
$ spago install

Example

From basic example.

Imports:

import Cheerio (Cheerio, find, length)
import Cheerio.Static (loadRoot)

Example html:

htmlEx :: String
htmlEx = """
  <ul id="fruits">
    <li class="apple">Apple</li>
    <li class="orange">Orange</li>
    <li class="pear">Pear</li>
  </ul>
"""

Load it and get the root element:

root :: Cheerio
root = loadRoot htmlEx

Use the query functions:

let fruitCount = root # find "#fruits" # find "li" # length
in log $ "Number of fruits: " <> show fruitCount

For more examples, please take a look at the unit tests. They cover most of the read-only cheerio functions.
