Thanks. That looks pretty straightforward. Is it possible to use that all on a command line invocation? Right now I have something like: 

perl -pe "s/^(.*?)\t(.*?)\|(.*?)\t(.*?)(?=\n)/<wrapper1>$1</wrapper1><
+wrapper2>$2\|$3</wrapper2><wrapper3>$4</wrapper3>/g;" inputfile

[download]
and then a follow-up to expand wrapper2 and the delimited fields within.
