body: <p>I am new to angularJs and while I am using ng-app and ng-view in HTML file, it is saying these are not valid attributes of element in HTML</p>
  
  <p>Can any one suggest </p>
  
  <p>Here is sample code:</p>
  
  <pre><code>&lt;html **ng-app**= "XXXXX" xmlns="http://www.w3.org/1999/xhtml"&gt;
      &lt;head&gt;
      &lt;/head&gt;
      &lt;body&gt;
          &lt;div **ng-view**&gt;&lt;/div&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
