I want to write a multi-line regex to match following requirement :
If ( leading "TEXT;" && LAYER is 131~137 && TEXTTYPE is 0)
(
get the text after "STRING"
)
so the above text result is "AVDD12"
following is my code , but it cannot work, please help! 
 #!/usr/bin/perl
use diagnostics;

while (<>) {
  if (/TEXT;\p{Space}* \n LAYER 13[1-7];\n TEXTTYPE\p{Space}* 0;\n .* 
+STRING/sxm) {
        print $1;
  }else{  
        print "not found!\n";
  }       
}
