用BeautifulSoup 分析HTML 標籤、屬性和值

BS4HTML.py

from bs4 import BeautifulSoup as soup
fin=open('web.htm', encoding='utf-8')  #將html檔案放置 web.htm(再轉換到fin開啟)
s=fin.read()
htm=soup(s,'html.parser')
print(htm.title.prettify())
print(htm.title.contents)
print(htm.contents[0])
print(htm.title.name)
print(htm.title.string)
print(htm.meta)
print(htm.meta['content'])
for item in htm.find_all('td'):
    print('item')
for item in htm.find_all('td',class_='table_head'):
    print('item')
for item in htm.find_all('td',class_=table_siteurl):
    print(item.a['href'])
