Python中类似jquery的HTML解析? [英] jquery-like HTML parsing in Python?

问题描述

是否有任何Python库可以让我解析类似于jQuery的HTML文档?

Is there any Python library that allows me to parse an HTML document similar to what jQuery does?

即我希望能够使用CSS选择器语法从文档中获取任意节点集，读取其内容/属性等.

i.e. I'd like to be able to use CSS selector syntax to grab an arbitrary set of nodes from the document, read their content/attributes, etc.

我之前使用过的唯一Python HTML解析库是BeautifulSoup，尽管很好，但我一直认为，如果我有jQuery语法，解析起来会更快. :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

推荐答案

如果您精通 BeautifulSoup ，您可以将 soupselect 添加到您的库中.
Soupselect是BeautifulSoup的CSS选择器扩展.

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 BeautifulSoup import BeautifulSoup as Soup
>>> from soupselect import select
>>> import urllib
>>> soup = Soup(urllib.urlopen('http://slashdot.org/'))
>>> select(soup, 'div.title h3')
