Just for a lark, I thought I'd attempt to import an XML file and view it within an HTML file. I am getting stuff to print on the screen, however the javascipt "document.write" function will only work once. It seems that if I don't reference variables from HTML below, it will complain. I downloaded the slashdot XML feed and had a go. So far it works if I put all the HTML in one "document.write" command as the second is ignored. Here is my code:
<html>
<head>
</head>
<BODY>
<script type="text/javascript" for="window" event="onload">
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM")
xmlDoc.async="false"
xmlDoc.load("slashdot.xml")
nodes = xmlDoc.documentElement.childNodes
url1.innerText=xmlDoc.getElementsByTagName("url").item(0).text
title1.innerText=xmlDoc.getElementsByTagName("title").item(0).text
image1.innerText=xmlDoc.getElementsByTagName("image").item(0).text
author1.innerText=xmlDoc.getElementsByTagName("author").item(0).text
url2.innerText=xmlDoc.getElementsByTagName("url").item(1).text
title2.innerText=xmlDoc.getElementsByTagName("title").item(1).text
image2.innerText=xmlDoc.getElementsByTagName("image").item(1).text
author2.innerText=xmlDoc.getElementsByTagName("author").item(1).text
url3.innerText=xmlDoc.getElementsByTagName("url").item(2).text
title3.innerText=xmlDoc.getElementsByTagName("title").item(2).text
image3.innerText=xmlDoc.getElementsByTagName("image").item(2).text
author3.innerText=xmlDoc.getElementsByTagName("author").item(2).text
document.write("<HR><A HREF=\'" + url1.innerText + "\'>" + title1.innerText + "</A><P>Submitted by " +author1.innerText+ "</P><IMG SRC=\'http://images.slashdot.org/topics/" + image1.innerText + "\'><HR><HR><A HREF=\'" + url2.innerText + "\'>" + title2.innerText + "</A><P>Submitted by " +author2.innerText+ "</P><IMG SRC=\'http://images.slashdot.org/topics/" + image2.innerText + "\'><HR><HR><A HREF=\'" + url3.innerText + "\'>" + title3.innerText + "</A><P>Submitted by " +author3.innerText+ "</P><IMG SRC=\'http://images.slashdot.org/topics/" + image3.innerText + "\'><HR>");
</script>
<span id="url1"></SPAN>

</BODY>
</HTML>
I have messed around with placement of 'body' and other html tags to no avail. If I am going about this all wrong, please let me know. I used a downloaded version of the slashdot feed, as it complains if I access it too often. Here is the format:
