Code Analysis
|
|
|
|
Objective:
|
|
The objective of the "scrape_text" function is to scrape the text content from
|
|
a given URL and return it as a string, after removing any unwanted HTML tags and
|
|
scripts.
|
|
|
|
Inputs:
|
|
- url: a string representing the URL of the webpage to be scraped.
|
|
|
|
Flow:
|
|
1. Send a GET request to the given URL using the requests library and the user agent
|
|
header from the config file.
|
|
2. Check if the response contains an HTTP error. If it does, return an error message.
|
|
3. Use BeautifulSoup to parse the HTML content of the response and extract all script
|
|
and style tags.
|
|
4. Get the text content of the remaining HTML using the get_text() method of
|
|
BeautifulSoup.
|
|
5. Split the text into lines and then into chunks, removing any extra whitespace.
|
|
6. Join the chunks into a single string with newline characters between them.
|
|
7. Return the cleaned text.
|
|
|
|
Outputs:
|
|
- A string representing the cleaned text content of the webpage.
|
|
|
|
Additional aspects:
|
|
- The function uses the requests library and BeautifulSoup to handle the HTTP request
|
|
and HTML parsing, respectively.
|
|
- The function removes script and style tags from the HTML to avoid including unwanted
|
|
content in the text output.
|
|
- The function uses a generator expression to split the text into lines and chunks,
|
|
which can improve performance for large amounts of text.
