I have a JavaScript function code where I want to alert.

function msgalert(x,y)
{
 tempstr = x.value
if(tempstr.length>y)
 {
  alert(c_AcknowledgementText);
  x.value = tempstr.substring(0,y);
  }
}

Now I have an xml with below format:

<?xml version="1.0" encoding="utf-8" ?>
<root>
    <key name="c_ContactUsHeading">Contact Us</key>
    <key name="c_AcknowledgementText">Comments can not be more than 250 characters.</key>
</root>

I want the JavaScript code so that the message shown in above alert can be read from above xml key name "c_AcknowledgementText".

I am trying with the below code, but unable to solve the problem, can you please have a look

    <script language="javascript" type="text/javascript">
function msgalert(x,y)
{
tempstr = x.value
    if(tempstr.length>y)
     {
            $(document).ready(function(){
        		$.ajax({
        			type: "GET",
        			url: "../includes/ResourceData.xml",
        			dataType: "xml",
        			success: function(xml) {					
        				$(xml).find('key').each(function(){
        					var title = $(this).find('name').text();						
        					);
        				});					
        			}
        		});
        	});
}
}
        </script>

some where I need to modify the above function so that I can use it to give alert value through XML.

I can't really understand what you're trying to do, but this code is wrong:

var title = $(this).find('name').text();

At that point, this is the current <key> element you are looping through. To get the value of the name attribute of this element, you would need to do this:

var title = $(this).attr('name');

And then to get the contents of this element, you would do:

var title = $(this).text();

In response to your comment, I think you want this:

var title = $(this).find('key[name=c_AcknowledgementText]').text();
alert(title);

I want to match that if attribute name="c_AcknowledgementText" then it should show the alert message of the text given in attribute c_AcknowledgementText. How can I do it? – Manoj Singh Jun 26 '09 at 11:50

So there are some different ways to go about this problem, you could

$(xml).find([name='key']).each(function(){
    alert($(this).text());                                                
});

This finds all elements where the name attribute equals 'key', and then it posts an alert with the text of that element.
