[QGIS-Developer] XYZ Tile source url from TOC

[matteo]

Hi guys,

if I don't get wrong Tile Layers are QgsRasterLayers objects.

Is there any method to grab from the loaded raster layer in the legend
the same url that is used to create the Tile in the Browser?

rl.source() gives the full url

'crs=EPSG:3857&format&type=xyz&url=http://a.tile.openstreetmap.org/%7Bz%7D/%7Bx%7D/%7By%7D.png&zmax=19&zmin=0'

Thanks for any hint

Matteo
