python - How can I get all the plain text from a website with Scrapy?

Question

I would like to have all the text visible from a website, after the HTML is rendered. I'm working in Python with Scrapy framework. With xpath('//body//text()') I'm able to get it, but with the HTML tags, and I only want the text. Any solution for this?

Answer 1

The easiest option would be to extract //body//text() and join everything found:

''.join(sel.select("//body//text()").extract()).strip()

where sel is a Selector instance.

Another option is to use nltk's clean_html():

>>> import nltk
>>> html = """
... <div class="post-text" itemprop="description">
... 
...         <p>I would like to have all the text visible from a website, after the HTML is rendered. I'm working in Python with Scrapy framework.
... With <code>xpath('//body//text()')</code> I'm able to get it, but with the HTML tags, and I only want the text. Any solution for this? Thanks !</p>
... 
...     </div>"""
>>> nltk.clean_html(html)

Another option is to use BeautifulSoup's get_text():

get_text()

If you only want the text part of a document or tag, you can use the get_text() method. It returns all the text in a document or beneath a tag, as a single Unicode string.

>>> from bs4 import BeautifulSoup
>>> soup = BeautifulSoup(html)
>>> print soup.get_text().strip()

Another option is to use lxml.html's text_content():

.text_content()

Returns the text content of the element, including the text content of its children, with no markup.

>>> import lxml.html
>>> tree = lxml.html.fromstring(html)
>>> print tree.text_content().strip()
