我需要的是在body标签之间提取文本（使用Scrapy xpath），但我根本不想要表格文本。
我试图获取所有文本的内容是：
def parse(self, response):
"""
-*-
"""
item = DummyItem()
title = response.xpath('//title/text()').extract()
body = "\n ".join(
response.xpath(
'//body//*[not(self::script or self::style)]/text()'
).extract()
)
item['title'] = title
item['body'] = body
yield item
在上面的节中，我设法提取所有我不想要的文本，包括表格。 然后我更换了＆＃34;身体＆＃34;用：
body = "\n ".join(
response.xpath(
'//body//*[not(self::table or self::script or self::style)]/text()'
).extract()
)
它没有完成这项工作。仍然提取表文本。
关于如何解决它的任何想法？
答案 0 :(得分：2)
您希望“所有不在 Intent i = this.getIntent();
u = i.getStringExtra("uname");
p = i.getStringExtra("pass");`
”中的文本节点，或“所有没有<table>祖先的文本节点”
XPath中的<table>。
/html/body//text()[not(ancestor::table)]现在您只需要从结果项中删除空格并从列表中删除空字符串。
text_nodes = response.xpath("/html/body//text()[not(ancestor::table)]").extract()
