Are there any way to filter out nulls from result?

See original GitHub issue

Hello, I have the following JSLT file:

{
  "formId": "Company",
  "fieldValues":
    [
        {
            "name": "CompanyName",
            "value": {
                "en_US": string(.data.companyName)
            }
        },
        if (contains("Android", array(.data.platforms)))
        {
            "name": "PlatformAndroid",
            "value": {
                "en_US": true
            }
        },
        if (contains("IOS", array(.data.platforms)))
        {
            "name": "PlatformIOS",
            "value": {
                "en_US": true
            }
        },
        if (contains("MicrosoftStore", array(.data.platforms)))
        {
            "name": "PlatformMicrosoftStore",
            "value": {
                "en_US": true
            }
        },
        {
            "name": "Pack",
            "value": {
                "en_US": string(.data.pack)
            }
        }
    ]
}

But the fieldValues array contains nulls if there are no platforms checked because of the behavior of if statement.

Before this solution, I tried to iterate over .data.platforms but I couldn’t because in this case the result will be a separated array. After that I tried to define a new function for that, but I couldn’t.

Do you have any idea? Thank you.

Hi @shark300

Follow the solution. Basically you transform all content in a array, then you print (with loop “for”) the elements != null

Jslt:

{ “formId”: “Company”, “fieldValues”: [for(array( [ { “name”: “CompanyName”, “value”: { “en_US”: string(.data.companyName) } }, if (contains(“Android”, array(.data.platforms))) { “name”: “PlatformAndroid”, “value”: { “en_US”: true } }, if (contains(“IOS”, array(.data.platforms))) { “name”: “PlatformIOS”, “value”: { “en_US”: true } }, if (contains(“MicrosoftStore”, array(.data.platforms))) { “name”: “PlatformMicrosoftStore”, “value”: { “en_US”: true } }, { “name”: “Pack”, “value”: { “en_US”: string(.data.pack) } } ] )). if( . != null)] }
