Primary installation method is with a Python package manager: pip install trafilatura. See installation documentation.

With Python

The only required argument is the input document (here a downloaded HTML file), the rest is optional.

>>> import trafilatura
>>> downloaded = trafilatura.fetch_url('https://github.blog/2019-03-29-leader-spotlight-erin-spiceland/')
>>> trafilatura.extract(downloaded)
# outputs main content and comments as plain text ...
>>> result = trafilatura.extract(downloaded, output_format="xml")
>>> print(result)
# formatting preserved in XML structure ...
>>> trafilatura.extract(downloaded, xml_output=True, include_comments=False)
# outputs main content without comments as XML ...

The use of fallback algorithms can also be bypassed in fast mode:

>>> result = trafilatura.extract(downloaded, no_fallback=True)
# shorter alternative to import and use the functions
>>> from trafilatura import fetch_url, extract
>>> extract(fetch_url('...'))

On the command-line

URLs can be used directly (-u/–URL):

$ trafilatura -u "https://github.blog/2019-03-29-leader-spotlight-erin-spiceland/"
# outputs main content and comments as plain text ...
$ trafilatura -h
# displays help message

You can also pipe a HTML document (and response body) to trafilatura:

$ cat myfile.html | trafilatura # use the contents of an already existing file
$ < myfile.html trafilatura # same here
