title: rvest function html_nodes returns {xml_nodeset (0)}
body: <p>I am trying to scrape data frame the following website</p>
  
  <p><a href="http://stats.nba.com/game/0041700404/playbyplay/" rel="nofollow noreferrer">http://stats.nba.com/game/0041700404/playbyplay/</a> </p>
  
  <p>I'd like to create a table that includes the date of the game, the scores throughout the game, and the team names</p>
  
  <p>I am using the following code:</p>
  
  <pre><code>game1 &lt;- read_html("http://stats.nba.com/game/0041700404/playbyplay/")
  
  #Extracts the Date
  html_nodes(game1, xpath = '//*[contains(concat( " ", @class, " " ), concat( " ", "game-summary-team--vtm", " " ))]//*[contains(concat( " ", @class, " " ), concat( " ", "game-summary-team__lineup", " " ))]')
  
  #Extracts the Score
  html_nodes(game1, xpath = '//*[contains(concat( " ", @class, " " ), concat( " ", "status", " " ))]//*[contains(concat( " ", @class, " " ), concat( " ", "score", " " ))]')
  
  #Extracts the Team names
  html_nodes(game1, xpath = '//*[contains(concat( " ", @class, " " ), concat( " ", "game-summary-team__name", " " ))]//a')
  </code></pre>
  
  <p>Unfortunately, I get the following </p>
  
  <pre><code>{xml_nodeset (0)}
  {xml_nodeset (0)}
  {xml_nodeset (0)}
  </code></pre>
  
  <p>I have seen a bunch of questions and answers to this problem but none of them seem to help.  </p>
