// grab the div and the first iframe inside it:
var iframe = document.getElementById('xyz').getElementsByTagName('iframe')[0];
// There are two different valid ways to set the height
// 1. Change the attribute like it was <iframe height="70" ... />
iframe.height = '70';
// 2. Change the attribute like it was <iframe style="height: 70px;" ... />
iframe.style.height = '70px';
