You can use the String.prototype.replace function to "loop" through all the relevant lines of the data. It accepts a regex pattern, and a function to handle the the matched text and return the replacement text. Here, however, we don't care about actually replacing anything; we just just use it to find each key/value pair
function parsePlaylist(data) {
var tracks = [], currentTrack;
// do a multi-line replace-all for "(key): (value)", but don't
// bother actually replacing anything, or storing the resulting
// string. We're just using it to walk through the data
data.replace(/^([^:]+):\s*(.+)$/gmi, function (match, key, value) {
// if this is the start of a new track (indicated
// by a "file" field), or the start of the loop,
// create a new object to hold the data
if( !currentTrack || key === "file" ) {
currentTrack = {};
tracks.push(currentTrack);
}
// add the key/value pair
currentTrack[key] = value;
});
return tracks;
}
That'll give you this:
