Scrapy没找到桌子 [英] Scrapy not finding table

问题描述

我正在尝试从 http：/ /www.oddsportal.com/basketball/usa/nba-2014-2015/results/

我想要的特定表有class =table-main

The particular table I want has class="table-main"

从scrapy response.xpath（'// table'）运行

running from scrapy response.xpath('//table')

In [28]:  response.xpath('//table')
Out[28]:
[<Selector xpath='//table' data=u'<table>\n\t\t\t\t\t\t\t\t<tr>\n\t\t\t\t\t<td c
lass="bol'>,
 <Selector xpath='//table' data=u'<table class="table-main top-event">\n\t\t\t'>
,
 <Selector xpath='//table' data=u'<table>\n\t\t\t\t\t<tr>\n\t\t\t\t\t\t<td>\n\t\
t\t\t\t\t\t<tab'>,
 <Selector xpath='//table' data=u'<table class="rm-bonus-offer">\n\t\t\t\t\t\t\t
\t<'>,
 <Selector xpath='//table' data=u'<table>\n\t\t\t\t\t<tr>\n\t\t\t\t\t\t<td>\n\t\
t\t\t\t\t\t<tab'>,
 <Selector xpath='//table' data=u'<table class="rm-bonus-offer">\n\t\t\t\t\t\t\t
\t<'>]

不会返回我想要刮的表。有人可以帮忙吗？

does not return the table I wish to scrape. Can anyone help?

推荐答案

Selector(response).xpath('//table[contains(@class, "table-main")]').extract_first()

我已经测试过，它有效。

I've tested, it works.

请参阅选择器在scrapy doc
