title: How to access a <div> from the HTML embedded by <object>
body: <p>I have a webpage that has several <code>&lt;div&gt;</code> sections ("navcol" and "maincol"). The "navcol" div contains <code>&lt;object data="mypage.html"&gt;</code>.  Inside mypage.html there are buttons the user can click to select pages to be inserted into "maincol". I need to gain access to the innerHTML of "maincol" in the main page with Javascript, so I can do the insertion (like using an iframe). Can someone put me on the right track? </p>
  
  <p>PS. I am using <code>&lt;object&gt;</code>, because I want to have HTML 4.0 "Strict" and Iframes are not in "Strict", but s are.</p>
