Array of array

Hello,

Is it possible to parse an array of array ?
Like :

{
“events”: [
{
“assets”: [
[ “bonus”, “/events/checkpoint-hard-on/bonus.png?PiPicZKT”, “image/png”, 499, 709, 0 ],
[ “bonus”, “/events/checkpoint-hard-on/bonus.jpg?EnSpC2oB”, “image/jpeg”, 1200, 630, 0 ]
],
“start”: “xxx”,
“end”: “xxxx”,
},
{
…
}
}

How to have access to display the second field (the url) of each element of the array assets ?
