Hi,
I want to extract certain tokens from a string in my DMN Decision tables using Regex. I use FEEL-Scala currently as the language.
Input : Your penalty for Form 940
Expected Output : 940
In the above example, i want to extract any number which follows the word ‘Form’. Plz note that, the number can be any, so i cannot really use ‘contains’.
Can someone help how can i achieve this in DMN Decision tables.
Hi @Chenbaga_M_K,
You can use the string function extract()

Hi @Chenbaga_M_K,
Below function extracts any sequence of digits of any length
extract("Your penalty for Form 940", "[0-9]*")
As per the docs, the result of extract function is a list of strings so the result of above example would be
["940"]
@hassang Thank you. I tried this even before and now again, but not sure why do i get “no function found with name ‘extract’ and 2 parameters”
This is how my expression looks like
extract(“penalty for Form 940 s”, “.Form (\d{3}).”)
The function extract()
is not available yet. It will be added with the new version of the FEEL engine 1.14
. (If you look at the docs for version 1.13 then you will not find this function.)
Until then, you could try to use the replace() function instead.
