Topic: split operation in mapping rules

Hello all,
In am trying to create Immunization resource using mapping rules.
In Immunization resource doseQuantity is of data type SimpleQuantity.
In my input json i have a field called dose which has both value an unit separated by a space between.
For E.g. "dose" : "<Some Value> <Unit> ", here before writing the mapping rule, I want to split the field "dose" from input json based on space and get the value and unit.
Is it possible to split any field based on a character/string in mapping rules.

yes, but you would need to split it in the target, e.g. you can use the fhirPath functions substring and indexOf, see an example here

Hello @Oliver Egger ,
Thank You for quick response , i tried this , but it is not working.
src->tgt.doseQuantity = create('SimpleQuantity') as doseQuantity then{
src.dose as dose->doseQuantity.value = dose.substring(0,dose.indexOf(' ') -1) "value";
src.dose as dose->doseQuantity.unit = dose.substring(dose.indexOf(' ')) "unit";
}"doseQuantity";
Input : "dose" : "0.5 ml"

@amit bodhwani try to use the evaluate() function or the shortcut () of it, e.g: doseQuantity.value = (%dose.substring(0,%dose.indexOf(' ') -1)) "value";

Thank you for quick response @Oliver Egger , it works using shortcut operator.

on a slightly off topic/related question, is there any effort to pull together common FML helper functions (e.g. split() ) into a library?
