using xml in javascript

[shailu]

Hi,

I am calling an xml using javasript.I am able to call the xml but the xml is getting cached on client machine forever.Even though if any changes done in the xml file still the cached xml is used from the client machine.Since the http request is used for calling a xml hence ideally the cached xml is used from the client machine untill its contents are changed.


Pls find the code I have used...

pls help before my boss kills me

// to load the xml
function loadreq(url)

{

// branch for native XMLHttpRequest object
if (window.XMLHttpRequest) {
req_Head = new XMLHttpRequest();
req = new XMLHttpRequest();
req.onreadystatechange = processReqChange;
req.send(null);
req.open("GET", url,true);
} else if (window.ActiveXObject) {
req = new ActiveXObject("Microsoft.XMLHTTP");
req_Head = new ActiveXObject("Microsoft.XMLHTTP");
if (req) {
req.onreadystatechange = processReqChange;
req_Head.open("HEAD", url,true);
req.open("GET", url, true);
req.send();

}
}
}


//to read the xml
function processReqChange()
{
if (req.readyState == 4) {
if (req.status == 200) {
var Gujarati_News ;
var response = req.responseXML.documentElement;
var news=response.getElementsByTagName("news")
i= 0
var news_texts ;
news_texts = ""

for(var i=0; i<= news.length-1; i++){
// create a string
news_texts = news_texts + "<a href='../quressan/news.asp?newsid=" + news[i].getAttribute("links") +"&typeid="+news[i].getAttribute("typeid")+"'><font size='2' color='#1c355d' face='arial'><b>*" + response.getElementsByTagName("news")[i].firstChild.nodeValue+ ">> </b></font></a>"

if(news[i].getAttribute("dt_tm")!=""){
dt_tm = news[i].getAttribute("dt_tm")
news_texts = news_texts + "<br><font size='1' color='#1c355d' face='arial'>(" + dt_tm + ")</font>"
}
news_texts = news_texts + "<br><br>"
}
news_text.innerHTML = news_texts ;

} else {
alert("There was a problem retrieving the XML data:\n" + req.statusText);
}
}
}
