title: Regex: Match the word between tags
body: <p>I have this almost 5000 html files with this meta tag, but with different content:</p>
  
  <pre><code>&lt;meta name="Abstract" content="I must &amp;#226;follow the path."/&gt;
  </code></pre>
  
  <p>I want to match only the <code>&amp;#226;</code>, from this particular tag. I made a regex, but doesn't work:</p>
  
  <pre><code>(?s)&lt;meta name="Abstract" content=(&amp;#226;)(.*\"/&gt;)
  </code></pre>
  
  <p>Basically, <code>&amp;#226;</code> means <code>â</code> in ANSI characters. I made a mistake and I got this into this meta tag. So, I need to replace all <code>&amp;#226;</code> with simple <code>a</code>, but only in this particular meta tab, not in whole files.</p>
