Html extract all text

Extract text from a webpage using BeautifulSoup and Python

If you’re going to spend time crawling the web, one task you might encounter is stripping out visible text content from HTML.

If you’re working in Python, we can accomplish this using BeautifulSoup.

Setting up the extraction

Here’s how you might download the HTML:

 import requests url = 'https://www.troyhunt.com/the-773-million-record-collection-1-data-reach/' res = requests.get(url) html_page = res.content 

Now, we have the HTML.. but there will be a lot of clutter in there. How can we extract the information we want?

Creating the «beautiful soup»

We’ll use Beautiful Soup to parse the HTML as follows:

 from bs4 import BeautifulSoup soup = BeautifulSoup(html_page, 'html.parser') 

Finding the text

BeautifulSoup provides a simple way to find text content (i.e. non-HTML) from the HTML:

 text = soup.find_all(text=True) 

However, this is going to give us some information we don’t want.

Look at the output of the following statement:

 set([t.parent.name for t in text]) #

There are a few items in here that we likely do not want:

For the others, you should check to see which you want.

Extracting the valuable text

Now that we can see our valuable elements, we can build our output:

 output = '' blacklist = [ '[document]', 'noscript', 'header', 'html', 'meta', 'head', 'input', 'script', # there may be more elements you don't want, such as "style", etc. ] for t in text: if t.parent.name not in blacklist: output += '<> '.format(t) 

The full script

Finally, here’s the full Python script to get text from a webpage:

 import requests from bs4 import BeautifulSoup url = 'https://www.troyhunt.com/the-773-million-record-collection-1-data-reach/' res = requests.get(url) html_page = res.content soup = BeautifulSoup(html_page, 'html.parser') text = soup.find_all(text=True) output = '' blacklist = [ '[document]', 'noscript', 'header', 'html', 'meta', 'head', 'input', 'script', # there may be more elements you don't want, such as "style", etc. ] for t in text: if t.parent.name not in blacklist: output += '<> '.format(t) print(output) 

Improvements

If you look at output now, you’ll see that we have some things we don’t want.

There’s some text from the header:

 Home \n \n \n Workshops \n \n \n Speaking \n \n \n Media \n \n \n About \n \n \n Contact \n \n \n Sponsor \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n Sponsored by: 

And there’s also some text from the footer:

 \n \n \n \n \n \n Weekly Update 122 \n \n \n \n \n Weekly Update 121 \n \n \n \n \n \n \n \n Subscribe \n \n \n \n \n \n \n \n \n \n Subscribe Now! \n \n \n \n \r\n Send new blog posts: \n daily \n weekly \n \n \n \n Hey, just quickly confirm you\'re not a robot: \n Submitting. \n Got it!

If you’re just extracting text from a single site, you can probably look at the HTML and find a way to parse out only the valuable content from the page.

Unfortunately, the internet is a messy place and you’ll have a tough time finding consensus on HTML semantics.

If you’re doing cross-browser testing, an HTML to text converter can come in handy. For example, if you’re writing tests for a part of a web application that ensures users can’t post HTML comments to your application, you can quickly create test cases for this scenario using this programme.

After removing the HTML tags from the data, you are left with only the strings that go between the HTML tags, but the tags themselves are no longer present.

How to extract text from HTML?

Depending on your specific use case and the tools you have available, there are a few different ways to extract text from HTML. Here are a few approaches you can take:

• A regular expression can be used to search through an HTML document and extract text. If you only want to extract specific pieces of text or work with a small amount of HTML, this can be a good option
• Most modern web browsers include developer tools that allow you to inspect and extract web page elements. If you need to extract text from a live web page but don’t want to deal with the hassle of loading the HTML into your programme, this can be useful.
• Depending on the programming language you use, libraries such as Readability.js for JavaScript can help you extract main content from an article while minimizing noise such as ads, sidebar, and others.

The approach you take will be determined by your specific requirements, such as the size and structure of the HTML, the information to be extracted, and the resources available. If you need to extract text from large amounts of HTML, an HTML parser is likely to be more efficient and error-free than a regular expression.
