"GET" multiple xml file in html

I am trying to show multiple xml file into html. I able get single xml file show in html table by using xmlhttp.open("GET", "204S_2000_02_17_00_30_357.xml", true). However, I can't get multiple xml file using this function.
I had tried using xmlhttp.open("GET", "*.xml", true) but doesn't get any output.
It's any solution or method to "GET" the multiple xml file into html?
Noted: xml file will continuously generate in folder with random name.(example 204S_2000_02_XX_XX_XX_XX.xml).
code that show single xml file in html table
function loadXMLDoc() {
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
myFunction(this);
}
};
xmlhttp.open("GET", "204S_2000_02_17_00_30_357.xml", true);
xmlhttp.send();
}
function myFunction(xml) {
//coding....
}

One HTTP request gets one HTTP response.
In general, you can't get multiple files back from a single request using a wildcard.
You could, if you wrote suitable server-side code, have the server recognise a wildcard in the URL and respond by (for example) sending a zip file containing all the files that matched, or generating a new XML document containing the contents of all the files that matched.
Generally, however, you will make a separate request for each resource you want. Having determined all the URLs you wanted to request, you would probably want to use an API that supported promises (i.e. fetch instead of XMLHttpRequest) so you could feed them into Promise.all and run the next stage of the program once you had collected all the data.

Javascript write to local XML file

I know there are several questions how to save changes in an XML file using Javascript, and the obvious answer is: use a server side language such as PHP.
In my case, the XML file is in the same directory as my html file locally on my computer, not on any server.
In my index.html I access the alphabets.xml this way:
function getAlphabets() {
var xhttp;var result;
xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
result = findAlphabets(this);
console.log(result);
}
};
xhttp.open("GET", "alphabets.xml", true);
xhttp.send();
}
I want to change some data in the xml file, and save it back there. Is there any possible way to do so in plain javascript?
Or another way, not using a server side language?

How to request, & output JSON from local browser storage using AJAX (not jQuery)

Is it posible to request a JSON object from my browsers local storage with Ajax? it's just a simple object that i made with Js, and converted into JSON.
I then stored it to local browser storage, but i'm not sure that will work, considering that it might only work to request from a server.
I have seen simular questions about this, but i only see examples of jQuery, not pure JavaScript and AJAX.
<p id="demo"></p>
<script>
var info = {
name: "Josh",
age: 22,
born: "New York"
};
var jason = JSON.stringify(info);
localStorage.setItem("myJason", jason)
var http = new XMLHttpRequest();
http.open("GET", "file:///D:/HTML%20Files/Nettside%20med%20JSON%20og%20AJAX/nettside.html", true);
http.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
document.getElementById("demo").innerHTML = this.responseText;
}
};
http.send();

If you are running the html file from the local disk then yes you can access it by navigating the file structure using "../" to go up a file, however if the HTML file has been loaded from a web server then the only way to access it is to use a file input and then read the file contents. The user must choose the file though.
Here is an article on reading binary data from a file that the user has selected.

how to get a html page as response in xmlhttprequest

var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
alert(this.responseText);
}
};
xhttp.open("GET", "https://zbapi.herokuapp.com/", true);
xhttp.setRequestHeader("Content-type", "application/json");
xhttp.send();
This is my code. It is returning html text but i want it to load html output.

It is returning html text but i want it to load html output.
alert expects to be passed plain text.
You need to put the HTML source code somewhere which expects HTML source code.
For example, the innerHTML of an Element object.
The URL you are requesting, however, includes relative URLs and has its own JS. It doesn't make much sense to request it with JS and then try to render it. You would also certainly be better off just triggering navigation with location = "https://zbapi.herokuapp.com/".

You need to parsing HTML page to JSON with some parser on the server and send parsed data to the client in JSON format. For example, Himalaya (in Node.js).
Official repository of Himalaya
or use html2json (NPM Repository) to parse on client

save blob audio file on server with xmlhttprequest

I'm working on an audio web application where you can play along with music and record yourself. I'm working with a recorder plugin and I'm trying to save what has been recorded in a folder on a server. I get a blob file from the plugin via this javascript code:
recorder.exportWAV(function(blob) {
var xhr = new XMLHttpRequest();
var url = '../../audio/recordings/test.wav';
xhr.open('POST',url,true);
xhr.onload = function(e) {
if (this.status == 200) {
console.log(this.responseText);
}
};
xhr.send(blob);
},'audio/wav');
I have never worked with this before so I'm not sure if my code is right. But I get no errors my file is just not saved. I have been searching the internet for this and what I have found is that a lot of people use a php file as url. Why? What php file are they using?
Thanks!
