Can't find a way to send post request

So my problem is that I'm tying to get the stroke values to send as a post request just like my script currently does the pointsattribute values in the post request... l: (JSON.stringify(line)) << Just like that in the post request but I need it to do the stroke values. So if it's possible to use something like c: (JSON.stringify(stroke))

I want to match the lines with their stroke colors and send the request with the color just like the line.

The stroke value is inside the style attribute of that SVG. Here's a image showing exactly what I need to log just like it does the points.

So yeah, simply parse and send it like it does the points values..

I've tried making a const just like the LINES but no luck.

xhr=new XMLHttpRequest();
xhr.open("GET", "http://colorillo.com/blqu.inline.svg");
xhr.addEventListener("load", function() {
const xmlDoc = new DOMParser().parseFromString(
this.responseText.trim(),
"image/svg+xml"
);
const Lines = Array.from(xmlDoc.getElementsByTagName('polyline'), pl => 
pl.getAttribute('points').split(' ').map(pair => 
pair.split(',').map(Number)));

Lines.forEach(line => $.post("/draw.php?ing=_index", {
                l: (JSON.stringify(line)), 
                w: ("1"),
                c: (JSON.stringify(Stroke)), //<<<< MY ERROR IS HERE!!!
                o: ("75"),
                f: ("1"),
                _: ("false")
            }));
});
xhr.send();
