So what I need is a simple script that receives an amount from another website and outputs it as raw text.

So theres 18.53 CHF currently HERE. That amount's always changing and i would like to "extract" this amount and have it as raw text shown on another website.

Is that possible?

You could do it with DOM elements, search through and find what class/tag it's in and scan the HTML for it. Or you could take a look and see if they have some form of API, I would look for you but I can't understand a word :P

You should be able to use something like jQuery's get method, and then write a script to parse for whichever class/tag the html you're after is in.

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
    $("button").click(function(){
        $.get("http://www.finanzen.ch/rohstoffe/silberpreis/CHF", function(data, status){
            alert("Data: " + data + "\nStatus: " + status);
        });
    });
});
</script>
</head>
<body>

<button>Button</button>

</body>
</html>

That's what i got so far. What else do i miss? I would need the data: part

Pointlessly using jQuery for basic DOM and XMLHttpRequest operations ... 9_9

 

But since you already added that nasty framework thingy, you could as well use it to parse the website. I assume you stored the HTML in a variable: 

var elemente = $(deinHTML);
var silberpreisTH = $('.main_left .pricebox th:first', elemente);

The .html() attribute of silberpreisTH contains your value.

 

edit: Or, even better, get yourself an OpenExchangeRates account (it's free), they provide plain-text JSON files for exchange rates, easy to parse without jQuery.

Write in C.
