学ぶ Working with Specific Elements | Decoding HTML with Beautiful Soup

Navigating an HTML document using Python attributes retrieves only the first occurrence of an element. If you want to find the first instance of an element without knowing its full path, use the .find() method and pass the tag name as a string (without < > brackets). For example, locate the first <div> element in the HTML document.


              123456789101112
            
# Importing libraries
from bs4 import BeautifulSoup
from urllib.request import urlopen

# Reading web page
url = "https://codefinity-content-media.s3.eu-west-1.amazonaws.com/18a4e428-1a0f-44c2-a8ad-244cd9c7985e/jesus.html"
page = urlopen(url)
html = page.read().decode("utf-8")

# Reading HTML with BeautifulSoup
soup = BeautifulSoup(html, "html.parser")
print(soup.find("div"))

You can also retrieve all instances of a specific element using the .find_all() method. It returns a list of all matches. For example, find all <p> tags in the HTML document.


              123456789101112
            
# Importing libraries
from bs4 import BeautifulSoup
from urllib.request import urlopen

# Reading web page
url = "https://codefinity-content-media.s3.eu-west-1.amazonaws.com/18a4e428-1a0f-44c2-a8ad-244cd9c7985e/jesus.html"
page = urlopen(url)
html = page.read().decode("utf-8")

# Reading HTML with BeautifulSoup
soup = BeautifulSoup(html, "html.parser")
print(soup.find_all("p"))

You can use the .find_all() method to locate multiple tags by passing a list of tag names. For example, collect all <div> and <title> elements.


              12345678910111213
            
# Importing libraries
from bs4 import BeautifulSoup
from urllib.request import urlopen

# Reading web page
url = "https://codefinity-content-media.s3.eu-west-1.amazonaws.com/18a4e428-1a0f-44c2-a8ad-244cd9c7985e/page.html"
page = urlopen(url)
html = page.read().decode("utf-8")

# Reading HTML with BeautifulSoup
soup = BeautifulSoup(html, "html.parser")
for el in soup.find_all(["div", "title"]):
  print(el)

すべて明確でしたか？
