循环遍历项目以提取html表的内容

时间：2015-04-15 02:45:31

标签： python scrapy

我对scrapy全新。我安装了它，我可以很简单地构建教程。我也可以通过

启动零碎的shell

scrapy shell＆＃34;网站＆＃34;

下表包含其他更高级别的内容，如div。使用scrapy，我该如何提取下表？我是否需要阅读div或者我可以直接跳到表中并提取信息吗？

我正在寻找的是这样的代码，它在dict中返回表中的所有项目，最好是在一个完全包含的代码中，我可以运行和学习：

def parse(self, response):
    hxs = HtmlXPathSelector(response)
    divs = hxs.select('//tr[@class="someclass"]')
    for div in divs:
        item['var1'] = div.select('//table/tbody/tr[*]/td[2]/p/span[2]
        yield item

注意：我从最后删除了重复的东西。

您可以根据里面的th元素找到表格，例如：

response.xpath("//table[.//th[. = 'Date']]")

您还可以找到检查其父母的表格：

response.css("div#flexBox_flex_calendar_mainCal > table")

来自Scrapy Shell的工作示例（表格中的打印时间值）：

In [1]: for row in response.css("div#flexBox_flex_calendar_mainCal table tr.calendar_row"): 
            print row.xpath(".//td[@class='time']/text()").extract()
[u'1:30am']
[u'2:45am']
[u'4:00am']
[u'4:15am']
[u'4:30am']
[u'4:45am']
[u'4:50am']
[u'4:55am']
[u'5:00am']
[u'5:30am']
[]
[u'6:01am']
[u'6:30am']
[u'6:36am']
