I'm messing around with lxml
in Python, but can't seem to figure out how to use the cssselect()
function to get all div
's with the class reddit-entry
, as it seems to dislike the -
character. Any other class name without -
works fine.
That's a bug in the parser in lxml.cssselect. I took over maintenance of the project and extracted it from lxml. The bug is fixed in the new cssselect: http://packages.python.org/cssselect/
lxml 2.4 will use the new cssselect, but until then the way to use it is:
from cssselect import HTMLTranslator
result = lxml_document.xpath(HTMLTranslator().css_to_xpath('div.reddit-entry'))
如果您通过xpath运行cssselector使用的代码,它确实可以工作...
obj.xpath("//div[contains(concat(' ', normalize-space(@class), ' '), ' reddit-entry ')]")
