Filter Single Item JSON Array?

Questions
1

Hello,

I use a HTML (extract HTML Content) node to filter a webpage and extract text for a specific class.
As output I get a (single item) JSON array like this :

[
  {
    "data": [
      "AAA BBB CCC",
      "AAA AA DDD",    <<< to keep
      "BBBB CCC",
      "AAAAA EE",
      "BBB FF",
      "C JJJ",
      "GG HHHHHHH",
      "II AAA AA HHH"   <<< to keep
    ]
  }
]

My goal is to filter items of this JSON array in order to keep those who match a pattern (eg AAA AA).

I tried the filter node (eg {{ $json.data }} contains "AAA AA" and code nodes without success.
I reviewed forums and tutorials without success either.
I’ve seen examples to iterate over multiple items but not for a single item array/list.

Does anyone have an example to achieve this ?
Thanks
Samp.
