title: How to skip html headings and find number with regex?
body: <p>I want to find NUMBER, but skip H1 , H2 , H3 and so on.. (all possible HTML heading variants)</p>
  
  <p>Example 1:</p>
  
  <pre><code>&lt;div&gt;Today is good day. I got&lt;h3&gt;3&lt;span&gt; lotto tickets&lt;/span&gt;&lt;/h3&gt;&lt;/div&gt;
  </code></pre>
  
  <p>Example 2:</p>
  
  <pre><code>I want to buy lotto tickets. &lt;h1&gt;Maybe 10 is enough&lt;/h1&gt;
  </code></pre>
  
  <p>Example 3:</p>
  
  <pre><code>I want to buy lotto tickets. &lt;h1&gt;4 or 5&lt;/h1&gt; is enough.
  </code></pre>
  
  <p>I have this code:</p>
  
  <pre><code>lotto tickets\D{0,15}(\d+\,\d+|\d+\.\d+|\d+)
  </code></pre>
  
  <p>But every time i get numbers from HTML tag.. <code>&lt;h3&gt;</code> (3) , <code>&lt;h1&gt;</code> (1).
  How i can skip them?</p>
  
  <p>In <strong>example 1</strong> i should get nothing</p>
  
  <p>In <strong>example 2</strong> i should get number <strong>10</strong></p>
  
  <p>In <strong>example 3</strong> i should get number <strong>4</strong></p>
  
  <p>(Numbers can be with <strong>.</strong> or <strong>,</strong> example: 2.5)</p>
