title: Web scraping: Extract text in R using RVEST
body: <p>I'm doing work for college using R, how I can extract information "<strong>| 20 de Novembro de 2015</strong>" using RVEST package? I tried to get the class "widget-info" but brought a "widget-author" class also</p>
  
  <pre><code>&lt;div class="home-list-content"&gt;
              &lt;span class="widget-info"&gt;
                  &lt;span class="widget-author"&gt;
                      Rúben Campanacho
                  &lt;/span&gt; 
                  | 20 de Novembro de 2015
              &lt;/span&gt;
              &lt;h2&gt;
                  LG Pay é o sistema de pagamentos móveis da LG
              &lt;/h2&gt;
          &lt;/div&gt;
  </code></pre>
  
  <p>My code:</p>
  
  <pre><code>pagina &lt;- read_html("http://www.tecnologia.com.pt")
      data &lt;- pagina %&gt;% 
        html_nodes(".widget-info") %&gt;%
        html_text() %&gt;%
        as.data.frame()
  </code></pre>
  
  <p>The result:</p>
  
  <pre><code>Rúben Campanacho | 20 de Novembro de 2015
  </code></pre>
  
  <p>I want just <strong>| 20 de Novembro de 2015</strong></p>
