我想使用Scrapy进行抓取。所以我为xpath或css选择器打开firefox或chrome来复制这个地址！我明白了！但这回归空！我在网站（检查元素）和response.body中使用jquery尝试此操作。它们都是一样但不起作用！例如，我的抓取页面是this 和地址是：
IN INSPECT ELEMENT:
{
FIREFOX CSS:
html body table tbody tr td div table tbody tr td center table tbody tr td table tbody tr td table.borderact tbody tr td h1
FIREFOX XPATH:
/html/body/table/tbody/tr/td/div/table[1]/tbody/tr/td[3]/center/table/tbody/tr/td[3]/table[1]/tbody/tr/td[2]/table/tbody/tr[1]/td/h1
CHROME CSS:
body > table > tbody > tr > td > div > table:nth-child(3) > tbody > tr > td:nth-child(3) > center > table > tbody > tr > td:nth-child(3) > table:nth-child(1) > tbody > tr > td:nth-child(2) > table > tbody > tr:nth-child(1) > td > h1
IN RESPONSE:
FIREFOX CSS:
html body table tbody tr td div table tbody tr td center table tbody tr td table tbody tr td table.\"borderact\" tbody tr td h1
FIREFOX XPATH:
/html/body/table/tbody/tr/td/div/table[1]/tbody/tr/td[3]/center/table/tbody/tr/td[3]/table[1]/tbody/tr/td[2]/table/tbody/tr[1]/td/h1
CHROME CSS:
