title: Web scraping with rvest - Unexpected behaviour
body: <p>I would like to scrape all the links from this web page with <code>rvest</code>: <a href="http://finanzalocale.interno.it/apps/revisori.php/albo_revisori/elencoRevisori/indice/15" rel="nofollow noreferrer">http://finanzalocale.interno.it/apps/revisori.php/albo_revisori/elencoRevisori/indice/15</a></p>
  
  <p>I have tried with the following: </p>
  
  <pre><code>library(rvest)
  
  url &lt;- read_html('http://finanzalocale.interno.it/apps/revisori.php/albo_revisori/elencoRevisori/indice/15')
  nodes &lt;- html_nodes(x = url, css = 'a') %&gt;%
           html_attr('href')
  </code></pre>
  
  <p>Rather than getting all of them, I only got 3. I had a look at the HTML structure of the page and there are definitely more links - particularly in the table. </p>
  
  <p>I then tried to get those ones - the table is in the <code>block_content</code> div:</p>
  
  <pre><code>url &lt;- read_html('http://finanzalocale.interno.it/apps/revisori.php/albo_revisori/elencoRevisori/indice/15')
  nodes &lt;- html_nodes(x = url, css = '.block_content') %&gt;%
           html_attr('href')
  </code></pre>
  
  <p>I didn't get any. How do I go ahead?</p>
