How to view the XML data using AJAX.

To view the XML data using AJAX, you can use the JavaScript XMLHttpRequest object to send a request to an XML file and retrieve the data. You can then use the responseText or responseXML properties of the XMLHttpRequest object to access the data and display it on your webpage. One common way to display the data is to use the innerHTML property of a DOM element to insert the data into the webpage. Another way is to use JavaScript to parse the XML data and create HTML elements dynamically to display the data.

Here is an example of using AJAX to view XML data:

var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
        var xmlDoc = this.responseXML;
        var x = xmlDoc.getElementsByTagName("book");
        for (i = 0; i < x.length; i++) {
            console.log(x[i].getElementsByTagName("title")[0].childNodes[0].nodeValue);
        }
    }
};
xhttp.open("GET", "books.xml", true);
xhttp.send();

In this example, an XMLHttpRequest object is created and the onreadystatechange property is set to a function that will execute when the state of the request changes. Within the function, the XML data is accessed using the responseXML property of the XMLHttpRequest object. The getElementsByTagName method is then used to access specific elements within the XML document and their values are logged to the console. The XML file "books.xml" is requested using the open and send methods of the XMLHttpRequest object.
