title: Get InnerHTML from Frameset
body: <p>i am trying to export the innerHTML from a FrameSet to excel (.xlsx).
  Is there a way für JavaScript like "this.document.getElementById('completeFrameSet').InnerHTML" ?</p>
  
  <pre><code>&lt;frameset onLoad="init()" onResize="balken()" framespacing="0" frameborder="0" cols="286,*" id="completeFrameSet"&gt;
     &lt;frameset id="links" rows="32,*"&gt;
       &lt;frame marginheight="0" marginwidth="0" scrolling="no" name="obLi" src="content_LeftTop.php &gt;
       &lt;frame marginheight="0" marginwidth="0" scrolling="no" name="untLi" src="content_LeftBottom.php"&gt;
     &lt;/frameset&gt;
     &lt;frameset id="rechts" rows="32,*"&gt;
       &lt;frameset id="oben" cols="*,13"&gt;
          &lt;frame marginheight="0" marginwidth="0" scrolling="no" name="obRe" src="content_RightTop.php"&gt;
          &lt;frame scrolling="no" src="leer.html"&gt;
       &lt;/frameset&gt;
       &lt;frame marginheight="0" marginwidth="0" scrolling="auto" name="untRe" src="content_RightBottom.php"&gt;
     &lt;/frameset&gt;
  &lt;/frameset&gt;
  </code></pre>
