beautifulsoup4 Xpath指定で要素を取得

Last updated at Posted at 2020-01-30

やり方

  • lxmlを使えばOK
    • beautifulsoup単体ではXpath指定不可

流れ

  1. beautifulsoupでhtmlをパースして、
  2. lxmlで変換すると、
  3. xpath指定できる!
.py
import urllib2
from lxml import html
from bs4 import BeautifulSoup

data = urllib2.urlopen("http://example.com")
soup_parsed_data = BeautifulSoup(data, 'html.parser')

lxml_coverted_data = html.fromstring(str(soup_parsed_data))

# あとはお好きにどうぞ
lxml_coverted_data.xpath('xxx/yyy/...')

Xpath書き方
