Question

我想以下列格式解析包含CDATA元素的xml

<showtimes><![CDATA[6:50 PM,https://www.movietickets.com/purchase.asp?afid=rgncom&house_id=6446&language=2&movie_id=87050&perft=18:50&perfd=03012011,9:40 PM,https://www.movietickets.com/purchase.asp?afid=rgncom&house_id=6446&language=2&movie_id=87050&perft=21:40&perfd=03012011]]> </showtimes>

请帮我找一个解决方案。

Answer 1

这不应该是任何问题 - 例如与lxml：

from lxml import etree

input = '<showtimes><![CDATA[6:50 PM,https://www.movietickets.com/purchase.asp?afid=rgncom&house_id=6446&language=2&movie_id=87050&perft=18:50&perfd=03012011,9:40 PM,https://www.movietickets.com/purchase.asp?afid=rgncom&house_id=6446&language=2&movie_id=87050&perft=21:40&perfd=03012011]]> </showtimes>'

f = etree.fromstring(input)
for s in f.xpath("//showtimes"):
    print s.text

...打印：

下午6:50，https：//www.movietickets.com/purchase.asp？afid = rgncom＆amp; house_id = 6446＆amp; language = 2＆amp; movie_id = 87050＆amp; perft = 18:50＆amp; perfd = 03012011,9：下午40点，https：//www.movietickets.com/purchase.asp？afid = rgncom＆amp; house_id = 6446＆amp; language = 2＆amp; movie_id = 87050＆amp; perft = 21:40＆amp; perfd = 03012011

Answer 2

我不确定你在找什么。这是基于一些疯狂假设的答案。

PS：此解决方案需要lxml。

>>> s = """<showtimes><![CDATA[6:50 PM,https://www.movietickets.com/purchase.asp?afid=rgncom&house_id=6446&language=2&movie_id=87050&perft=18:50&perfd=03012011,9:40 PM,https://www.movietickets.com/purchase.asp?afid=rgncom&house_id=6446&language=2&movie_id=87050&perft=21:40&perfd=03012011]]> </showtimes>"""
>>> from lxml import etree
>>> import urlparse
>>> doc = etree.fromstring(s)
>>> _time, url = doc.text.split(',', 1)
>>> _time # Not sure if you want this
'6:50 PM'
>>> for key, value in urlparse.parse_qs(urlparse.urlsplit(url).query).items():
    print key, value


perfd ['03012011,9:40 PM,https://www.movietickets.com/purchase.asp?afid=rgncom', '03012011 ']
movie_id ['87050', '87050']
language ['2', '2']
perft ['18:50', '21:40']
afid ['rgncom']
house_id ['6446', '6446']
>>>

据我所知，standard python SAX解析器正确处理CDATA。你将能够解析它。
