Import XML data into a database using PhoneGap and the powerful combination of jQuery and AJAX

Hello everyone, I could really use some assistance here. I am currently working on an app using Phonegap/JQuery mobile and I need help parsing XML data and storing it in a SQLite database. Can someone guide me on how to achieve this within a JavaScript function?

I have a good understanding of how to parse the XML data, but I am struggling with the process of saving it locally into the SQLite database that is accessible through Phonegap. Below is the XML data I am working with:

<?xml version="1.0" encoding="UTF-8"?>
 <orders>
    <order>
        <orderId>123456789</orderId>
        <city>Cincinnati</city>
        <state>Ohio</state>
        <zip>45451</zip>
    </order>
 </orders>

Here is a sample JavaScript function for parsing this XML data:

$(document).ready(function(){
    $.ajax({
    type: "GET",
    url: "testOrders.xml",
    dataType: "xml",
    success: function(xml) {
      $(xml).find('order').each(function(){
        orderId = $(this).find("orderId").text();
        city = $(this).find("city").text();
        state = $(this).find("state").text();
        zip = $(this).find("zip").text();
         $("#acceptedOrdersContent").append('<div>');
         $("#acceptedOrdersContent").append('<h3>'OrderId: '+ orderId + '</h3>');
         $("#acceptedOrdersContent").append('<p>');
         $("#acceptedOrdersContent").append('City: '+ city + '<br />');
         $("#acceptedOrdersContent").append('State: '+ state + '<br />');
         $("#acceptedOrdersContent").append('Zip: '+ zip +'<br />');
         $("#acceptedOrdersContent").append('</p>');
         $("#acceptedOrdersContent").append('</div>');
            });
        }
     });
 });

Thank you in advance for your help!

Setting up the database:

let database = openDatabase('PhoneGap_db', '1.0', '', 2 * 1024 * 1024);

Creating a new table:

database.transaction(function (tx) {
  tx.executeSql('CREATE TABLE IF NOT EXISTS orders (id unique, city, state, zip)');
});

Inserting data into the table:

database.transaction(function (tx) {
  tx.executeSql('INSERT INTO orders (id, city, state, zip) VALUES (orderId, city, state, zip)');
});

For optimal performance, it's recommended to include the INSERT operation within the AJAX response handler:

$.ajax({
    type: "GET",
    url: "testOrders.xml",
    dataType: "xml",
    success: function(xml) {
      $(xml).find('order').each(function(){
        orderId = $(this).find("orderId").text();
        city = $(this).find("city").text();
        state = $(this).find("state").text();
        zip = $(this).find("zip").text();
        database.transaction(function (tx) {
           tx.executeSql('INSERT INTO orders (id, city, state, zip) VALUES      (orderId, city, state, zip)');
        });
            });
        }
     });

Best of luck with your implementation!
