您可以使用字典将文章分成几个部分，将标题作为关键字，将段落作为内容。这样就可以更容易地确定哪个是标题，哪个文本属于哪个文章。
例如：

import scrapy

class NewsSpider(scrapy.Spider):
    name = "travelandleisure"

    def start_requests(self):
        url = "https://www.travelandleisure.com/travel-news/where-can-americans-travel-right-now-a-country-by-country-guide"

        yield scrapy.Request(url, callback=self.parse_dir_contents)

    def parse_dir_contents(self, response):
        sections = {}
        header,paragraphs  = "main", []
        for element in response.xpath('//*[@id="mntl-sc-page_1-0"]/*'):
            tag = element.re(r"<(\w+)\s")  # get the tag name
            # if its a paragraph add it to the paragraph list
            if tag[0] == "p":              
                paragraphs += element.xpath(".//text()").getall()
            # if it's a heading place the heading and paragraphs in the
            # dictionary and start a new heading with the current text.
            elif tag[0] == "h3":
                sections[header] = ''.join(paragraphs)
                header = ' '.join(element.xpath(".//text()").getall()).strip()
                paragraphs = []
        yield sections  # yield all sections
