The split function splits a string based on the splitter given and saves the result in an array.

Syntax

output = split(expression, splitter)

Inputs

expression : a reference to a variable or any [[expression|Expressions]]. splitter : a string or a character based on which you want to split the string

Output

output : an array of strings resulted from splitting input.

Example flow

Schema splitWordSchema {
    splitWord1 [string word1]
    splitWord2 [string word1]
    splitWord3 [string word1]
    splitWord4 [string word1]
    splitWord5 [string word1]
    splitWord6 [string word1]   
}

Schema wordSchema {
    string word1
    string word2
    string word3
    string word4
    string wordSplit
}

value dummyWord -> wordSchema {
    "a|b|c"
    "a.b.c"
    "[CS]v1|2C0872A1051D7A42-6000190C600082FB[CE]"
    "null"
}


Mapping splitMapping input dummyWord as dummyWord output splitWordSchema {
    splitWordSchema.splitWord1 = if(contains(dummyWord.word1,"a")) then split(dummyWord.word1,"\\|") else null
    splitWordSchema.splitWord2 = split(dummyWord.word2,"\\.")
    splitWordSchema.splitWord3 = split(dummyWord.word3,"\\|")
    splitWordSchema.splitWord4 = if(!contains(dummyWord.word4,"a")) then split(dummyWord.word4,"\\|") else null
    splitWordSchema.splitWord5 = split(dummyWord.word1,"\\.")
    splitWordSchema.splitWord6 =    split(splitWordSchema.splitWord3[1],"\\[") 
}
