使用Beautiful Soup提取H2标签中的文本内容

Let's break down what's going wrong with your current code, then fix it to extract the text from those <h2> tags correctly.

What's Off in Your Current Code #

• Each item in your data list is already an <h2> tag object. When you call item.findAll('h2'), you're asking that single h2 tag to find more h2 tags inside itself (which don't exist), and this returns a list of elements. Lists don't have a get_text() method—that's why your code throws an error.
• Your code also has indentation issues: Python relies on indentation to define code blocks, so the for loop needs to be properly indented under the variable assignment.

Correct Approach #

Assuming you've already parsed your HTML with Beautiful Soup, here's how to extract the text properly:

Step 1: Parse HTML and Fetch Target H2 Elements

First, correctly grab all the <h2> tags using their specific class:

from bs4 import BeautifulSoup

# Replace this with your actual HTML content
html_content = """
<h2 class="ArticleBody-styles-makeit-subtitle--LnHeO">1. Python</h2>
<h2 class="ArticleBody-styles-makeit-subtitle--LnHeO">2. HTML</h2>
"""

# Parse the HTML
soup = BeautifulSoup(html_content, "html.parser")

# Get all h2 tags matching the class
data = soup.find_all("h2", class_="ArticleBody-styles-makeit-subtitle--LnHeO")

Step 2: Extract Text from Each Tag

Now that data is a list of <h2> tag objects, loop through them and call get_text() directly on each item:

for item in data:
    # Extract and print the inner text
    print(item.get_text())

This will output exactly what you need:

1. Python
2. HTML

Key Notes #

• Use class_ instead of class in the find_all() call—class is a reserved keyword in Python, so Beautiful Soup uses class_ to target CSS classes.
• If you only need a single <h2> tag instead of all matching ones, use soup.find() (singular) instead of find_all()—this returns a single tag object, not a list.
