I have installed WPS extension at GeoServer.I have generated the WPS request using GeoServer's WPS Request Builder. For it I have chosen process=gs:Bounds, Process inputs=VECTOR_LAYER and chosen any one vector layer among I have uploaded then chosen option "Generate XML from process inputs/outputs' from WPS Request Builder. After it one XML file has been generated and i have saved i with .xml extension.
I have created one website using HTML,CSS ans Java Script.
Now I want to access this XML file from the website. How could i define that code?

After you get the XML you just need to do a POST request with it. As an example:
<!DOCTYPE html>
<html>
<head>
<title>WPS Example</title>
</head>
<body>
<h1>How to send WPS request using HTML</h1>
<div><button onclick="getBounds()">Get Bounds</button></div>
<p id="result"></p>
<script>
var getBounds = function () {
var FEATURES_COLLECTION = '{ "type": "Polygon", "coordinates": [ [ [100.0, 0.0], [101.0, 0.0], [101.0, 1.0], [100.0, 1.0], [100.0, 0.0] ] ] }';
var GEOSERVER_URL = 'http://localhost/geoserver';
var myHeaders = new Headers();
myHeaders.append("Content-Type", "application/xml");
var raw = '<?xml version="1.0" encoding="UTF-8"?>\
<wps:Execute version="1.0.0" service="WPS"\

var requestOptions = {
method: 'POST',

body: raw,
redirect: 'follow'
};
fetch(GEOSERVER_URL + "/wps", requestOptions)
.then(response => response.text())
.then(result => {
document.getElementById("result").innerText = result;
console.log(result);
})
.catch(error => console.log('error', error));
};
