Java Help needed in removing intermediate segments from a pipe delimited segment file

Hi,

I just stuckup in doing some regular expressions on a file.

I have data which has multiple FHS and BTS segments like:

FHS|12121|LOCAL|2323
MSH|10101|POTAMAS|2323
PID|121221|THOMAS|DAVID|23432
OBX|2342|H1211|3232
BTS|0000|MERSTO|LIABLE
FHS|12121|LOCAL|2323
MSH|10101|POTAMAS|2323
PID|121221|THOMAS|DAVID|23432
OBX|2342|H1211|3232
BTS|0000|MERSTO|LIABLE
FHS|12121|LOCAL|2323
MSH|10101|POTAMAS|2323
PID|121221|THOMAS|DAVID|23432
OBX|2342|H1211|3232
BTS|0000|MERSTO|LIABLE

I am trying to have an output which will have only one FHS at the beginning and one BTS in the ending.
And all other FHS and BTS in the middle should be deleted.

The output should look like :

FHS|12121|LOCAL|2323
MSH|10101|POTAMAS|2323
PID|121221|THOMAS|DAVID|23432
OBX|2342|H1211|3232
MSH|10101|POTAMAS|2323
PID|121221|THOMAS|DAVID|23432
OBX|2342|H1211|3232
MSH|10101|POTAMAS|2323
PID|121221|THOMAS|DAVID|23432
OBX|2342|H1211|3232
BTS|0000|MERSTO|LIABLE


I will be glad if you give me some light in solving this problem.

Thanks in advance.

NAME
tagpending - tags bugs that are to be closed in the latest changelog as pending SYNOPSIS
tagpending [options] DESCRIPTION
tagpending parses debian/changelog to determine which bugs would be closed if the package were uploaded. Each bug is then marked as pending, using bts(1) if it is not already so. OPTIONS
-n, --noact Check whether any bugs require tagging, but do not actually do so. -s, --silent Do not output any messages. -v, --verbose List each bug checked and tagged in turn. -f, --force Do not query the BTS, but (re)tag all bugs closed in the changelog. --comments Include the changelog header line and the entries relating to the tagged bugs as comments in the generated mail. This is the default. Note that when used in combination with --to, the header line output will always be that of the most recent version. --no-comments Do not include changelog entries in the generated mail. -c, --confirm Tag bugs as both confirmed and pending. -t, --to version Parse changelogs for all versions strictly greater than version. Equivalent to dpkg-parsechangelog's -v option. -i, --interactive Display the message which would be sent to the BTS and, except when --noact was used, prompt for confirmation before sending it. -w, --wnpp For each bug that does not appear to belong to the current package, check whether it is filed against wnpp. If so, tag it. This allows e.g. ITAs and ITPs closed in an upload to be tagged. SEE ALSO
