我一直试图在Scrapy中连接一些嵌套文本和xpath。我认为它使用xpath 1.0?我看了一堆其他职位,但似乎没有得到相当我想要的东西在Scrapy中连接Xpath嵌套文本
下面是HTML的特定部分(实际页http://adventuretime.wikia.com/wiki/List_of_episodes):
<tr>
<td colspan="5" style="border-bottom: #BCD9E3 3px solid">
Finn and Princess Bubblegum must protect the <a href="/wiki/Candy_Kingdom" title="Candy Kingdom">Candy Kingdom</a> from a horde of candy zombies they accidentally created.
</td>
</tr>
<tr>
<td colspan="5" style="border-bottom: #BCD9E3 3px solid">
Finn must travel to <a href="/wiki/Lumpy_Space" title="Lumpy Space">Lumpy Space</a> to find a cure that will save Jake, who was accidentally bitten by <a href="/wiki/Lumpy_Space_Princess" title="Lumpy Space Princess">Lumpy Space Princess</a> at Princess Bubblegum's annual 'Mallow Tea Ceremony.'
</td>
</tr>
(much more stuff here)
这里是我的结果想回:
[u'Finn and Princess Bubblegum must protect the Candy Kingdom from a horde of candy zombies they accidentally
created.\n', u'Finn must travel to Lumpy Space to find a cure that will save Jake, who was accidentally bitten', (more stuff here)]
我已经使用了答案试图从 HTML XPath: Extracting text mixed in with multiple tags?
description =sel.xpath("//table[@class='wikitable']/tr[position()>1]/td[@colspan='5']/parent::tr/td[descendant-or-self::text()]").extract()
但这只是让我回来
[u'<td colspan="5" style="border-bottom: #BCD9E3 3px solid">Finn and Princess Bubblegum must protect the <a href="/wiki/
Candy_Kingdom" title="Candy Kingdom">Candy Kingdom</a> from a horde of candy zombies they accidentally created.\n</td>',
的string()
答案似乎并没有对我也工作...我回来只有一个条目清单,并应该有很多。
我已经得到最接近的是:
description = sel.xpath("//table[@class='wikitable']/tr[position()>1]/td[@colspan='5']//text()").extract()
,这让我回
[u'Finn and Princess Bubblegum must protect the ', u'Candy Kingdom', u' from a horde of candy zombies they accidentally
created.\n', u'Finn must travel to ', u'Lumpy Space', u' to find a cure that will save Jake, who was accidentally bitten, (more stuff here)]
任何人有XPath的技巧上串联?
谢谢!
编辑:蜘蛛代码经由手动join()
class AT_Episode_Detail_Spider_2(Spider):
name = "ep_detail_2"
allowed_domains = ["adventuretime.wikia.com"]
start_urls = [
"http://adventuretime.wikia.com/wiki/List_of_episodes"
]
def parse(self, response):
sel = Selector(response)
description = sel.xpath("//table[@class='wikitable']/tr[position()>1]/td[@colspan='5']//text()").extract()
print description
'加入()'是不是完全是我要找的。我应该更具体一点。请注意,在我想要返回的数据中,不止有一个字符串。我只想将文本与其他标签组合在一起,但不是将所有文本和标签组合在一起。我会更新我的html真的很快... – pyramidface
@pyramidface你可以也可以用'join()来解决它。除此之外,您可能需要遍历行以制作说明列表。你还可以发布完整的蜘蛛代码,以便我可以更好地理解上下文吗?谢谢! – alecxe
@pyramidface好的,我已经更新了答案,包括获取描述列表的代码。这是你问的吗?谢谢。 – alecxe
