問題描述
是否有任何 Python 庫可以讓我解析類似于 jQuery 的 HTML 文檔?
Is there any Python library that allows me to parse an HTML document similar to what jQuery does?
即我希望能夠使用 CSS 選擇器語法 從文檔中抓取任意一組節點，讀取它們的內容/屬性等.
i.e. I'd like to be able to use CSS selectors syntax to grab an arbitrary set of nodes from the document, read their content/attributes, etc.
我以前使用過的唯一 Python HTML 解析庫是 BeautifulSoup，盡管它很好，但我一直認為如果我有可用的 jQuery 語法，我的解析會更快.:D
The only Python HTML parsing lib I've used before was BeautifulSoup, and even though it's fine I keep thinking it would be faster to do my parsing if I had jQuery syntax available. :D
推薦答案
如果你精通BeautifulSoup，您只需將 soupselect 添加到您的庫中.
Soupselect 是 BeautifulSoup 的 CSS 選擇器擴展.
If you are fluent with BeautifulSoup, you could just add soupselect to your libs.
Soupselect is a CSS selector extension for BeautifulSoup.
用法:
from bs4 import BeautifulSoup as Soup
from soupselect import select
import urllib
soup = Soup(urllib.urlopen('http://slashdot.org/'))
select(soup, 'div.title h3')
