XML Datafeed Help - Almost there...just need a hand!?

Hi I have an xml datafeed from http://xmlfeed.laterooms.com/index.aspx?aid=4066&r...

I have made a local xml copy http://www.cytravel.co.uk/test/html/england.xml

And currently the page displays ok here http://www.cytravel.co.uk/test/html/cheap_hotels_i...

What I actually want to do is make all the "region_descriptions" linkable using the url next to them so "Central and South England" should jst be clickable through to http://www.laterooms.com/en/p4066/r242_hotels-in-c... and the same for each region (preferably with an alt tag that states "click here for cheap hotels in (region_description)

The code I am currently using is below...please can someone help me as it is driving me nuts!!

TIA

<script type="text/javascript">

var xmlDoc;

if (window.XMLHttpRequest)

{

xmlDoc=new window.XMLHttpRequest();

xmlDoc.open("GET","england.xml",false);

xmlDoc.send("");

xmlDoc=xmlDoc.responseXML;

}

// IE 5 and IE 6

else if (ActiveXObject("Microsoft.XMLDOM"))

{

xmlDoc=new ActiveXObject("Microsoft.XMLDOM");

xmlDoc.async=false;

xmlDoc.load("england.xml");

}

document.write("<table border='1'>");

var x=xmlDoc.getElementsByTagName("region");

for (i=0;i<x.length;i++)

{

document.write("<tr><td>");

document.write(x[i].getElementsByTagName("region_description")[0].childNodes[0].nodeValue);

document.write("</td><td>");

document.write(x[i].getElementsByTagName("region_url")[0].childNodes[0].nodeValue);

document.write("</td></tr>");

}

document.write("</table>");

</script>

Update:

Can you please stop listing paysites..I just need a couple of lines tweaking..but I can't work out which ones :-(

Update 2:

The text above is all trunicated hence you cannot read the code, I have uploaded the full explanation in a text file to http://www.cytravel.co.uk/test/help.txt

I am desperate to get this project underway so any help would be very appreciated

    Hi OKBusinessGroup,

    I use the createDOM() method to transform the responseText into a DOM document:

    <script type="text/javascript">

    var xmlDoc;

    function createDOM(sXml){

    var browser = navigator.appName;

    var oXmlDom = null;

    if(browser == "Microsoft Internet Explorer") {

    oXmlDom=new ActiveXObject("Microsoft.XMLDOM");

    oXmlDom.async="false";

    oXmlDom.loadXML(sXml);

    }

    else {

    var oParser = new DOMParser();

    oXmlDom = oParser.parseFromString(sXml, "text/xml");

    }

    return oXmlDom;

    }

    function loadXMLDoc(url){

    xmlDoc=null;

    if(window.XMLHttpRequest){

    xmlDoc=new XMLHttpRequest();

    }

    else if (window.ActiveXObject){

    xmlDoc=new ActiveXObject("Microsoft.XMLHTTP");

    }

    if(xmlDoc!=null){

    xmlDoc.onreadystatechange=stateChange;

    xmlDoc.open("GET",url,false);

    xmlDoc.send(null);

    }

    }

    function stateChange(){

    if(xmlDoc.readyState==4){

    if(xmlDoc.status==200){

    var xmlres = createDOM(xmlDoc.responseText);

    var country = xmlres.getElementsByTagName('country')[0];

    var regions = country.getElementsByTagName('region');

    document.write("<table border='1'>");

    for(var i = 0; i < regions.length; i++){

    document.write("<tr><td>");

    var tag1 = regions[i].getElementsByTagName("tag1");

    document.write(tag1[0].childNodes[0].nodeValue);

    document.write("</td><td>");

    var tag2 = regions[i].getElementsByTagName("tag2");

    document.write(tag2[0].childNodes[0].nodeValue);

    document.write("</td></tr>");

    }

    document.write("</table>");

    }

    }

    }

    window.onload = function(){

    loadXMLDoc('england.xml');

    }

    </script>

    england.xml

    <?xml version="1.0" encoding="windows-1250"?>

    <country>

    <region>

    <tag1>yep</tag1>

    <tag2>nope</tag2>

    </region>

    <region>

    <tag1>hey</tag1>

    <tag2>wow</tag2>

    </region>

    <region>

    <tag1>yes</tag1>

    <tag2>ok</tag2>

    </region>

    </country>

    Best regards,

    EDIT:

    One line got truncated:

    var country = xmlres. getElementsByTagName ('country')[0];
