title: Scrapy extract URL (href) element without tags
body: <p>I have managed to extract some data with the following program. However, when I check over the extract data result, I realise I could not grab the href element (the url) included in the 'question_content' if there is url inside the content.</p>
  
  <pre><code>import scrapy
  
  class JPItem(scrapy.Item):
      best_answer = scrapy.Field()
      question_content = scrapy.Field()
      question_title = scrapy.Field()
  
  class JPSpider(scrapy.Spider):
  
      name = "jp"
      allowed_domains = ['detail.chiebukuro.yahoo.co.jp']
  
      start_urls = [
          'https://detail.chiebukuro.yahoo.co.jp/qa/question_detail/q' + str(x)
          for x in range (12174460000,12174470000)
      ]
  
      def parse(self, response):
          item = JPItem()
  
          item['question_title'] = response.css("div.mdPstd.mdPstdQstn.sttsRslvd.clrfx div.ttl h1::text").extract_first()
          item['question_content'] = ''.join([i for i in response.css("div.mdPstd.mdPstdQstn.sttsRslvd.clrfx div.ptsQes p::text").extract()])
          item['best_answer'] = ''.join([i for i in response.css("div.mdPstd.mdPstdBA.othrAns.clrfx div.ptsQes p.queTxt::text").extract()])
  
          yield item

  <p>As seen from the picture, there is a url which I am not able to catch it in the "::text" format, but if omitting the "::text", will get other unrelated data and tags like, i.e. br, p. </p>
  
  <p><strong>How can I do to just also grab that link while not including the br and p tag?</strong> </p>
