      title_reg = r'<h1 class="title" id="[\d]+">(.*?)</h1>'
      content_reg = r'<div class="card-summary-content">(.*?)</p>'
      title = re.compile(title_reg).findall(html)
      content = re.compile(content_reg).findall(html)
      title[0] = re.sub(r'<[^>]*?>', '', title[0])
      content[0] = re.sub(r'<[^>]*?>', '', content[0])
