Making an Array from an XML with Firefox vs Explorer

[djmanfros]

Hello!

I've an XML like this:

<XML id=SlideShowData>
 <SlideShowData>
  <SLIDES>
   <SLIDE FileName="filename1.jpg" Caption="descrizione1"/>
   <SLIDE FileName="filename2.jpg" Caption="descrizione2"/>
  </SLIDES>
 </SlideShowData>
</XML>
 

My javascript should create an Array from this XML. It works with Explorer while returns "parent has no properties" error with Firefox.

This is the two functions:

function InitSlideData()
{var SlidesNode = 
FindChildNode(SlideShowData.documentElement, "SLIDES");  
  if (SlidesNode == null)
    return;
  var ChildNodes = SlidesNode.getElementsByTagName("SLIDE");
 
  for (i = 0; i < ChildNodes.length; i++) 
    {SlideImages[i] = ChildNodes.item(i).attributes.getNamedItem("FileName").value;
    SlideCaptions[i] = ChildNodes.item(i).attributes.getNamedItem("Caption").value;
    }
 }
 
function FindChildNode(parent, name)
{ var ChildNodes = parent.getElementsByTagName(name); //here occurs the error!!
for (i = 0; i < ChildNodes.length; i++)
    if (ChildNodes.item(i).nodeName == name)
      return ChildNodes.item(i);
return null;    
}

Please help me, thankyou in advance!

On line 3, you use the variable SlideShowData. Where is it defined?

It's not defined.
Isn't enough <XML id=SlideShowData>?
How should I define it?
Why with IExplorer it works?

thank you very much!

You can define it using:

var SlideShowData = document.getElementById("SlideShowData");

I shouldn't work in IE either, but it messes things up with IDs by making them accessible globally.
