You're over-complicating the code. This isn't helped by having nested "fein"
nodes. So your fein array will have 4 items. Why not just loop through the
company items?
var company_array = xml.getElementsByTagName("compamy");
for (var i = 0; i < company_array.length; i++)
{
document.write("<p>" + company_array[i].text + "</p>");
}
I also suggest setting:
xml.async = false;
before loading the xml document as otherwise with a larger document the
parser will not have finished building the dom tree before you start
examining it.
