in reply to Regular Expression help, MS Access Pipe delimited export gone bad

How about this:
#!/usr/bin/perl -w use strict; my ($line, $spacer); while(defined($_=<>)) { s/\n//g; if ($_ =~ /^[0-9]{3,5}/) { print "$line\n" if defined($line); $line=$_; } else { $spacer = (/^\|/ || $line =~ /\|$/) ? "" : " "; $line.="$spacer$_"; } } print "$line\n"; #get last one...
If a line starts or ends with a pipe ("|"), then it assumes you do not want extra whitespace around it. Otherwise, it should honor any leading and trailing whitespace on each line (so if one line ends with a tab, and the next starts with one, the code will spit out two tabs in a row).
