Question

So this is really getting on my nerves. I needed to explain this a bit better so here it is. I\'m trying to make my script log in google\'s console a specific way. I\'ve got

Answer 1

Your code was almost there, but what you were logging to the console was ridiculous, since it was just the points attribute, unmodified

So, something like this

const polylines = Array.from(xmlDoc.getElementsByTagName('polyline'));
const Lines = polylines.map(pl => pl.getAttribute('points').split(' ').map(pair => pair.split(',').map(Number)));

Lines.forEach(line => console.log(JSON.stringify(line)));

Or, given that the second argument to Array.from is a map function, you can further simplify the code to

const Lines = Array.from(xmlDoc.getElementsByTagName('polyline'), pl => pl.getAttribute('points').split(' ').map(pair => pair.split(',').map(Number)));

Lines.forEach(line => console.log(JSON.stringify(line)));

Note, the console.log is done AFTER the processing

as for the comment

Lines.forEach(line => {
    // here you can post each line to whatever you need
});
