Struggling with Queries

[mfreeman-xtivia]

Given some input JSON like:

{"foo" : [
  {"name": "Smith", "age": 22},
  {"name": "Jones", "age": 30},
  {"name": "Doe", "age": 35}
]}

what is the JSLT expression that one would use to extract age "where name==Jones"?

[contatolucascosta]

That's it.

let ageJones = array([for(.foo).age if(.name=="Jones")])[0]

{ "AgeJones" : $ageJones }
