title: Find missing words in rows in Notepad++
body: <p>I have a folder with 2 kind of sentences/rows. One that has <code>&lt; h1 &gt;</code> tag, and other doesn't. Like so:</p>
  <pre><code>&lt; td class=&quot;articles&quot;&gt;Mama&lt; /td&gt;
  &lt; td class=&quot;articles&quot;&gt;&lt; h1&gt;Tata &lt; /h1&gt;&lt; /td&gt;
  </code></pre>
  <p>I want to find with Notepad++ only the rows that doesn't have the word <code>&lt; h1&gt;</code></p>
  <p>Does anybody know how to do this?</p>
