title: How to modify a HTML file with angular schematics
body: <p>Let's say we have an existing angular component including <strong>menu.component.html</strong> :</p>
  
  <pre><code>&lt;ul&gt;
    &lt;li&gt;&lt;a href="/home"&gt;home&lt;/a&gt;&lt;/li&gt;
    &lt;li&gt;&lt;a href="/about"&gt;about&lt;/a&gt;&lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>The goal is to add a new link with angular schematics, just after "about"</p>
  
  <pre><code> &lt;li&gt;&lt;a href="/contact"&gt;contact&lt;/a&gt;&lt;/li&gt;
  </code></pre>
  
  <p>Any ideas?</p>
