To extract a sub list from a given list (of strings) which matches a give string at the beginning

Sonu Chopra

Hello,

I want to extract a sub-list from a given list which matches a given string at beginning

For Example :- 

Given list   a = ("RM_1" "RM_2" "RM_5" "RM_6" "SRM_1" "SRM_5" "SRM_6" "M_5" "M_6")

                  b = "RM" (String to match to given list)

                Expected Output = ("RM_1" "RM_2" "RM_5" "RM_6")

I want String to match exactly at the beginning but at the end it can be anything.

I am referring to this Post  https://community.cadence.com/cadence_technology_forums/f/custom-ic-skill/38267/search-list-and-return-the-match-list but it also return ("SRM_1" "SRM_5" "SRM_6") which is not desired for me.

Can you please help me out on this point.

Regards

Sonu

    Hello Max ,

    The issue is that list b is stored in some Variable and I don't know what is exactly inside list b . So , I can't use "^RM" Directly. This Example was just for Reference.

    Not sure I understand this - in your example b is not a list but a variable containing the string that should be at the beginning of matching list elements. So correctly the setof() function should look like this:

    a = '("RM_1" "RM_2" "RM_5" "RM_6" "SRM_1" "SRM_5" "SRM_6" "M_5" "M_6")
    b="RM"
    (setof el a (pcreMatchp (strcat "^" b) el))
