Filtering JMESPath with contains

JMESPath is a query language for JSON, used by Azure.

Using its own example given from http://jmespath.org/ 

{
  "locations": [
    {"name": "Seattle", "state": "WA"},
    {"name": "New York", "state": "NY"},
    {"name": "Bellevue", "state": "WA"},
    {"name": "Olympia", "state": "WA"}
  ]
}

How to list all locations whose name contains a letter "l", or a string "le"? thx.

Solution

  • Filtering by character and by string works the same.

    query locations w/ names containing "l"

    locations[?name.contains(@, `l`)]

    Result:

    [
  {
    "name": "Seattle",
    "state": "WA"
  },
  {
    "name": "Bellevue",
    "state": "WA"
  },
  {
    "name": "Olympia",
    "state": "WA"
  }
]

    query locations w/ names containing "le"

    locations[?name.contains(@, `le`)]

    Result:

    [
  {
    "name": "Seattle",
    "state": "WA"
  },
  {
    "name": "Bellevue",
    "state": "WA"
  }
]

    query locations w/ names containing either "ue" or "ia"

    locations[?name.contains(@, `ue`) || name.contains(@, `ia`)]

    Result:

    [
  {
    "name": "Bellevue",
    "state": "WA"
  },
  {
    "name": "Olympia",
    "state": "WA"
  }
]
