title: Cannot import data using HTML Scraping
body: <p>So I am making a python project where I've decided to make a supermarket comparison thing. I've decided to leech the prices from an existing supermarket comparison website.</p>
  
  <p>I used this website to learn:
  <a href="https://docs.python-guide.org/scenarios/scrape/" rel="nofollow noreferrer">https://docs.python-guide.org/scenarios/scrape/</a></p>
  
  <p>To start I've attempted to fetch the price of apples (at Tesco) from this website:</p>
  
  <p><a href="http://www.mysupermarket.co.uk/tesco-price-comparison/Fruit/Tesco_Gala_Apple_Approx_160g.html" rel="nofollow noreferrer">http://www.mysupermarket.co.uk/tesco-price-comparison/Fruit/Tesco_Gala_Apple_Approx_160g.html</a></p>
  
  <p>using an edited version of the docs code which is:</p>
  
  <pre><code>import requests
  from lxml import html
  page = requests.get('http://www.mysupermarket.co.uk/tesco-price-comparison/Fruit/Tesco_Gala_Apple_Approx_160g.html')
      tree = html.fromstring(page.content)
      price_tesco = tree.xpath('//*[@id="PriceWrp"]/div[2]/span')
      print(price_tesco)
  </code></pre>
  
  <p>I've tried the xpath code for the price but when I print the price, it returns nothing (an empty list)</p>
  
  <p>So how would I fix this?</p>
  
  <p>Note - I am new to HTML Scraping and have a basic knowledge of python but decided to have a bit of a challenge.</p>
  
  <p>Thanks in advance.</p>
