getting data from an xml path to javascript

[chomp99]

Hello,

This might be a fairly easy task but I am having trouble finding a simple description on how to implement this. I have an xml path (has a url and that url is updated on this external file). I want to be able to setup javascript to get that url from that xml path and assign it to a variable so that I can create a second variable that merges the first value with other other values

example:
xml path:

http://www.url.com/links.xml

the data in that path is:
<links>
<link name="123" ref="

http://www.someurlhere.com"/>

</links>

I want to merge the ref value with other values:

http://www.someurlhere.com

with ?var1=123&var2=abc

final url

http://www.someurlhere.com?var1=123&var2=abc

Can someone help, I think the main question has to do with just getting the data out of the xml into a javascript variable.

thanks in advance for your help

Search on Google.com for xpath javascript, lots of results there

This is how you do it in ie.
[tt]
<script language="javascript">

var surl="

http://www.url.com/links.xml";

var oparser=new ActiveXObject("Msxml2.DomDocument");
oparser.async=false;
oparser.validateOnParse=false;
oparser.load (surl);
if (oparser.parseError.errorCode == 0) {
var onode=oparser.documentElement.selectSingleNode("/links/link") //underlying assumption made here
var sref=onode.getAttribute("ref");
var sname=onode.getAttribute("name");
var shref=sref+"?var1="+sname+"&var2=abc"; [green]//answer[/green]
} else {
var shref=""; //error occurred
}
onode=null;
oparser=null;

</script>
[/tt]
It might be appeared inside a function or some handler.

Different platform, you have to do similar corresponding script.
