Regular Expressions 101

You would like to scan a folder containing many files (Example : *.pb, *.pbi, *.pbp and *.pbf) and you are interested only by two type of files (example : *.pb and *.pbi). This expression will match only if extension match (in this case *.pb and *.pbi) otherwise no reaction. Feel free to change file...

We have a pipe delimited text file and each new record is separated by a CRLF. Each record has a fixed number of pipes, but not every column or field is valued, so there may be 2 or more pipes together. Is there a way to write a regex to parse out the third or fifth value? Many thanks in advance.

There are 2 segments within this data that start with REF* and end with a tilde (~). I can capture one of them but not both. I've read and cant seem to figure this one out. I DO need to preface with the NM1*03 piece.
