"Scrapy截取长字符串"

Question

我想从论坛帖子中提取文本数据。这是我的工作蜘蛛：

import scrapy
import csv #not used yet


class QuotesSpider(scrapy.Spider):
    name = "quotes2"
    start_urls = [
        'https://www.motor-talk.de/faq/mercedes-e-klasse-w210-q89.html#Q3512477',
    ]

    def parse(self, response):
        xString= ' '
        xStringLink = ' '

        for i in range(4, 6): # start, stop
            xString='//*[@id="questions"]/div[2]/div['+str(i)+']/div[2]/div[1]/table/tr/td/div/text()'
            xStringLink='//*[@id="questions"]/div[2]/div['+str(i)+']/a/@name'

            scraped_info = {
                'forum post': response.xpath(xString).extract(),
                'link': response.xpath(xStringLink).extract()
            }
            yield scraped_info

但是，我只得到以下输出：如您所见，论坛帖子被切断：（：

实际上，这些帖子要长得多，但字符串只是被切断了。你知道吗
