title: Extract raw HTML in react-native-render-html custom renderer
body: <p>I'm using react-native-render-html to render html.
  The <code>renderers</code> method allows me to provide custom function to render a particular tag. However I want to replace the children with my custom component, using the raw inner HTML from the source.</p>
  <p>Consider. I have the below html snippet provided to <code>&lt;HTML /&gt;</code> component:</p>
  <pre class="lang-html prettyprint-override"><code>&lt;a&gt; &lt;b&gt; &lt;c meta=&quot;xyz&quot;&gt; Some text &lt;/c&gt; &lt;b&gt; &lt;/a&gt;
  </code></pre>
  <p>and I have a custom renderer which returns a component that takes a html string and does some magic with it:</p>
  <pre class="lang-js prettyprint-override"><code>const renderers = {
    c: () =&gt; (
      &lt;Custom html={/** how do I get &quot;&lt;c meta=&quot;xyz&quot;&gt; Some text &lt;/c&gt;&quot;? */} /&gt;
    )
  }
  </code></pre>
