Links in xml looks like this

<Diretktreduktion_02>
<![CDATA[http://www.site.com/steel_agg_dr_article_en.html]]>
</Diretktreduktion_02>
.......

First I parsed links from xml to html,

Code:

---

<script type="text/javascript">
    jQuery(function ($) {
        $.ajax({
            type: "GET",
            url: 'steel_en_process.xml',
            dataType: "xml",
            success: loadDiagramData
          });
          function loadDiagramData(xml) {

              $(xml).find("aggregate_links").each(function() {
                var pfannen  = $(this).find('Pfannenbehandlung_05').text();
                var elektro  = $(this).find('Elektrolichtbogenofen_04').text();
                var brammen  = $(this).find('Brammen_Strangguss_07_01').text();
                var pfannen_1 = $(this).find('Pfannenbehandlung_05_01').text();
                var direkt    = $(this).find('Diretktreduktion_02').text();
                var torpedo  = $(this).find('Torpedopfanne_09').text();
                var hochofen  = $(this).find('hochofen_01').text();
                var brammen_1 = $(this).find('Brammen_Strangguss_07').text();
                var vakuum    = $(this).find('vakuumbehandlung_06').text();
                var sauers    = $(this).find('Sauerstoffkonverter_03').text();

Then, I want to assign in an appropriate <div> and on click, link should get additional value "view=asIframe" and iframe should be displayed like this - http://prnt.sc/d9kbz3

Code:

---

Event.observe(window, 'load', function() {
 var overlayElements = $$('#content_items a.background-color--black');
 
 for(i=0; i<overlayElements.size(); i++) {
  overlayElements[i].observe('click', function(event) {
  openOverlayPopup(this.href);
  event.stop();
  });
 }
});function openOverlayPopup(url) {
 contentUrl = url+"?view=asIframe";
/* Fix the height of the overlay */
myLightWindow._getPageDimensions();
document.getElementById("lightwindow_overlay").setStyle({ height: myLightWindow.pageDimensions.height + 'px'});
 myLightWindow.activateWindow({
  href: contentUrl,
  title: '',
  height: 560,
  width: 540,
  type: 'external'
 });
}

---

Ok, I did something, but what is happening now...

Code:

---

Event.observe(window, 'load', function() {
  var overlayElements = $$('.lightwindow');
 
  for(i=0; i<overlayElements.size(); i++) {
    overlayElements[i].observe('click', function(event) {
    openOverlayPopup(this.href);
    event.stop();
    });
  };
  });
  function openOverlayPopup(url) {
  contentUrl = url+"?view=asIframe";
  /* Fix the height of the overlay */
  myLightWindow.activateWindow({
    href: contentUrl,
    title: '',
    height: 560,
    width: 540,
    type: 'external'
  });
  };

---

With this code, onclick I managed to add view=asIframe at the end of link, but the frame does not get dimensions (height 560px and width 540px) and set it as params, but has dimensions width 100% and height 100%, which causes the iframe is a very very huge. Can you help me how to fix ?
