Introduction to BeautifulSoup get text
BeautifulSoup obtain text refers to the practise of extracting text from a website’s HTML or XML content with the use of web scrapers, which are software robots. This data-gathering tool is a Python package. By working in tandem with a parser, BeautifulSoup facilitates iteration, searching, and customization of the parser’s output (in the form of a parse tree). Because of this, using BeautifulSoup for web crawling is a breeze.

What is BeautifulSoup get text?
- Handling the documents of XML and HTML requires several parsers, such as lxml and html parser.
- BeautifulSoup allows us to travel around the HTML document tree and edit it programmatically in addition to extracting data.
- BeautifulSoup is typically used with the requests package, which gets a page from which BeautifulSoup extracts the data.
- A string is one of the most basic types of filter. BeautifulSoup will do a match on a string if we pass it to the search method. We can search for all tags that begin with a specific string or tag.
- The get text method in BeautifulSoup is used to get the text from an element. We can use it by simply invoking the object method. However, because the object represents a string, get text does not operate on Navigable String.
- BeautifulSoup gives several parameters to help us refine our search, one of which is a string.
- We have a variety of filters that we are passing into this method, and it’s essential to understand them because they’re used often throughout the search API.
- These filters can be applied to tags based on their names, attributes, string text, or combination.
- The HTML file can be found in the anchor tag a>, span span span>, paragraph tag p>, and other tags. As a result, the lovely soup assists us in obtaining our desired output, such as extracting paragraphs from a specific url/html file.
- BeautifulSoup package for extracting information from HTML and XML documents. Python doesn’t include this module by default.
- Queries make it incredibly simple to send HTTP/1.1 requests. Unfortunately, python does not include this module as well.
BeautifulSoup get text Web Pages
The instructions below outline how to use BeautifulSoup to generate a sample of “get text” web pages:
First, use the pip command to get the bs4 package installed. Because the bs4 package has already been installed on our system and the example below assumes that it is, this precondition will be seen to be met and further action will be unnecessary. Code:
Resulting pip install bs4
:
2. Here, we begin by installing the bs4 package, then proceed to install the other packages. In the following example, because the requests package is already present in the system, the requirement will be marked as fulfilled and no further action will be required. Code:
Produced pip install requests
:
After all the modules have been installed, the python3 command is used to launch the python shell. Code:
Resulting python3
:
In this fourth step, after entering the python shell, we verify (through bs4) that the requests package has been added to our distribution. Code:
The Results of a import bs4
CPU are:
import requests
Five, after making sure we have all we need, we bring in the bs4 and request packages libraries. Code:
The Results of the from bs4 import BeautifulSoup
Algorithm
import requests
6. At this stage, when the library has been imported, the URL is assigned; in this case, we utilise the Google URL. Code:
Output
:
url = https://www.google.com/
Step 7: We now get the raw HTML content from the URL we just assigned. Code:
Output py_con = requests.get(url).text
:
8. In this stage, we get raw HTML material, parse through the content, and then print the text based on our findings. Code:
Generating py_soup = BeautifulSoup(py_con, "html.parser")
:
print(py_soup.find('title').text)
BeautifulSoup get text Method
Code:
- The URLLib method corresponds to the specified URL. After obtaining the HTML using the urlopen (html).read() function, BeautifulSoup’s get text() method is used to acquire the HTML text.
- NLTK.clean html() is recommended in a few NLP publications. However, in the latest NLTK implementation, the NLTK.clean html method is deprecated.
- To remove HTML markup, utilise BeautifulSoup’s get text() function, according to the NLTK.clean html technique.
- Once HTML content has been acquired, use the NLTK word tokenize method to recover words and punctuations.
- Then, using word filtering techniques, we can further filter out terms that fit the criteria, such as word length.
- We may also use NLTK Text to construct frequency distributions using NLTK. The below example shows BeautifulSoup get text method.
Resulting from bs4 import BeautifulSoup
import requests
py_url = "https://www.google.com/"
py_con = requests.get (py_url).text
py_soup = BeautifulSoup (py_con, "html.parser")
print (py_soup.find ('title').text)
0
- In the above example, after assigning the URL, we fetched the raw content after parsing the content using the py_soup variable.
BeautifulSoup get text Tags
Number-Code
- Every time a tag is closed, BeautifulSoup get text and adds a new line character. Therefore, there are situations when we need to split it by br> tags rather than the correct tags.
- The below example shows the use of BeautifulSoup get text.
The Results of the html = """<div class="soup">
Algorithm
BeautifulSoup get text tags
BeautifulSoup get text.
BeautifulSoup <a class="get" href="soup.com">text</a>
BeautifulSoup.
BeautifulSoup get text tags.
</div>"""
from bs4 import BeautifulSoup
import requests
py_soup = BeautifulSoup(html, "lxml")
py_ele = py_soup.find("div", class_="soup")
print (py_ele.get_text(separator=" "))
1
For demonstration purposes, we will substitute strings for all tags in the code below. Code:
Resulting html = """<div class="soup">
BeautifulSoup get text tags
BeautifulSoup get text.
BeautifulSoup <a class="get" href="soup.com">text</a>
BeautifulSoup.
BeautifulSoup get text tags.
<br>
</div>"""
from bs4 import BeautifulSoup
import requests
html = html.replace ("<br>", "python")
py_soup = BeautifulSoup(html, "lxml")
py_ele = py_soup.find("h1")
py_out = py_out.replace ("python", "\n")
