title: Reliable method of scraping page source i.e the tv at the beginning of each line?
body: <p>When extracting data you can use CSS/xpaths.  But is there a similar or reliable method of doing this in the page source. </p>

  <p>You could get the page source and then parse using Regex but probably not be reliable if for instance the tv did not load on the page. I have looked up various solutions but I have yet to find one that mentions getting every tv at start of each line (1, 4, 7 etc,, in source) or using a reliable method e.g Css/xpaths in source of a page. </p>
  
  <p>What would is the golden standard of reliable method of doing what I am after?</p>
