Chopper is a tool to extract elements from HTML by preserving ancestors and CSS rules.

Compared to other HTML parsers Chopper is designed to retain original HTML tree but eliminate elements that do not match parsing rules. Meaning, we can parse HTML elements and keep thei structure for machine learning or other tasks where data structure is needed as well as the data value.

Example Use


HTML = """
<html>
  <head>
    <title>Test</title>
  </head>
  <body>
    <div id="header"></div>
    <div id="main">
      <div class="iwantthis">
        HELLO WORLD
        <a href="/nope">Do not want</a>
      </div>
    </div>
    <div id="footer"></div>
  </body>
</html>
"""

CSS = """
div { border: 1px solid black; }
div#main { color: blue; }
div.iwantthis { background-color: red; }
a { color: green; }
div#footer { border-top: 2px solid red; }
"""

extractor = Extractor.keep('//div[@class="iwantthis"]').discard('//a')
html, css = extractor.extract(HTML, CSS)

# will result in:
html
"""
<html>
  <body>
    <div id="main">
      <div class="iwantthis">
        HELLO WORLD
      </div>
    </div>
  </body>
</html>"""

css
"""
div{border:1px solid black;}
div#main{color:blue;}
div.iwantthis{background-color:red;}
"""
