awk extended pattern matching (embedding pattern matching in actions for already matched strings) [closed]

Question

I want handle strings of the form:

PREFIX_TYPE_N,DATA

So, does the *awk (gawk, mawk, nawk) support including pattern matching in the action for already matched string? Something like this (of course, doesn't work for me):

*awk 'BEGIN { FS="," }
     /PREFIX/ {
                /TYPE_1/  {printf "[TYPE1] [DATA: $2]"}    // <-- included pattern 
                /TYPE_2/  {printf "[TYPE2] [DATA: $2]"}    // <-- another included pattern
                ...                                        // <-- some more included patterns
              }' "filename"

Or do I still need if/else or switch/case?

Answer 1

This should work, but I'm not an expert of awk so there might be better answers if you wait:

*awk 'BEGIN { FS="," }
     /PREFIX/ {
                if ($0 ~ /TYPE_1/)  {printf "[TYPE1] [DATA: $2]"}    // <-- included pattern 
                if ($0 ~ /TYPE_2/)  {printf "[TYPE2] [DATA: $2]"}    // <-- another included pattern
                ...                                        // <-- some more included patterns
              }' "filename"
