OpenLayer 3 read KML /Document/name - openlayers-3

Question

Is there a way to read the KML /Document/name to set a layer title within an OpenLayers 3 map?
I have some dynamic KML layers, and I would like to read the titles from the KML layers themselves.
I am currently using code like this to load my KML layers.
layer = new ol.layer.Vector({
source: new ol.source.Vector({
url: kmlurl,
format: new ol.format.KML({
extractStyles: true
})
})
});
map.addLayer(layer);
Currently using OL 3.6.0.
Are there any events I can hook into to get at the raw KML so I can parse it manually?
thanks!

It's possible to do it with jQuery. Use this following code.
The code take the first element with the tag 'Folder' and give the content of the first tag called 'name'.
var url = 'data/my_kml_file.kml'; // your kml file
var elemTagName = 'Folder'; // the element you want the name
// jQuery
$.get( url , function( kmlDatas ) {
var myElem = kmlDatas.getElementsByTagName( elemTagName )[0];
var myElemName = myElem.getElementsByTagName( "name" )[0].innerHTML;
console.info( "KML " + elemTagName + " name: " + myElemName );
});
'elemTagName' got the value 'Folder' because i don't see a 'name' tag in 'Document' of my KML files. Instead there is a 'Folder' > 'name'.
If you really want to use 'Document' > 'name' , just replace the elemTagName by 'Document'.
