Updated

Description

Parses a JSON string, constructs a value of the set type and sends it through the result output.

Properties

Specific

Value

EXPRESSION (string)

JSON string to be parsed.

Inputs

seqin

SEQ | OPTIONAL

A standard sequence input.

text

DATA(string) | MANDATORY

The input through which the JSON string to be parsed is received. This input can be deleted (we delete it in the Flow – Inputs list) if it is not needed, i.e. if we want to parse a string obtained by evaluating an arbitrary expression set through Value property.

Outputs

seqout

SEQ | OPTIONAL

A standard sequence output.

result

DATA(any) | MANDATORY

Data output to which the constructed value is sent. The type of that value must be specified – this should be done in the Flow – Outputs section:

In the JSON example mentioned below, we have a JSON string that looks like this:

[
    {
        "country": "Afghanistan",
        "city": "Kabul"
    },
    {
        "country": "Albania",
        "city": "Tirana"
    },
    {
        "country": "Algeria",
        "city": "Alger"
    },
    ...
]

The constructed value returned by this Action should be of type array:CountryCity, where CountryCity is a structure that has two fields (the name of the structure CountryCity is arbitrarily chosen by the developer):

  • country, whose type is string
  • city, whose type is string

The definition of that structure looks like this in the Project editor:
