Now that we have BeautifulSoup installed, let’s turn our attention to its documentation. Understanding the documentation is crucial for harnessing the full power of the library.
- BeautifulSoup Official Documentation: The official documentation is a treasure trove of information, covering everything from basic usage to advanced techniques. Take your time to explore it, and don’t hesitate to refer back to it as you dive deeper into BeautifulSoup.
Practical Examples and Tutorials
Basic BeautifulSoup Example
from bs4 import BeautifulSoup
# Create a sample HTML document
html_doc = """
<html>
<head>
<title>Sample Page</title>
</head>
<body>
<h1>Welcome to BeautifulSoup!</h1>
<p>This is a simple example.</p>
</body>
</html>
"""
# Parse the HTML document
soup = BeautifulSoup(html_doc, 'html.parser')
# Print the title
print(soup.title.text)
# Print the first paragraph
print(soup.p.text)In this fundamental case, we make an HTML report, parse it with BeautifulSoup, and extract the title and the primary paragraph.
Locating Elements by Class
from bs4 import BeautifulSoup
# HTML document with multiple elements of the same class
html_doc = """
<html>
<body>
<div class="content">Element 1</div>
<div class="content">Element 2</div>
<div class="content">Element 3</div>
</body>
</html>
"""
# Parse the HTML document
soup = BeautifulSoup(html_doc, 'html.parser')
# Find all elements with class="content"
elements = soup.find_all(class_="content")
# Print the text of each element
for element in elements:
print(element.text)In this example, we demonstrate how to find and extract elements based on their CSS class.
Parsing XML with BeautifulSoup
from bs4 import BeautifulSoup
# XML document
xml_doc = """
<data>
<item id="1">Item 1</item>
<item id="2">Item 2</item>
<item id="3">Item 3</item>
</data>
"""
# Parse the XML document
soup = BeautifulSoup(xml_doc, 'xml')
# Find an element by ID
element = soup.find(id="2")
# Print the text of the element
print(element.text)Here, we show how to use BeautifulSoup to parse XML documents and locate elements by their unique IDs.
