Hi gbwien,

your code is based on a suggestion I made a few days ago in another thread that you opened (http://www.perlmonks.org/?node_id=1209051).

But, in that post, based on the data that you had originally shown, I was using an MSISDN line to detect the beginning of the new record block. You're now showing data where there is not always a line with an MSISDN. So you need to use something else to detect the beginning of a record. See my solution posted today (http://www.perlmonks.org/?node_id=1209603), where <SUBEND is used to detect the end of a block.

As I already pointed out in that previous thread, you're using too many parentheses in your regex, making your life more difficult than it needs to be.

For example, replace: 

if (/^(\t*MSISDN=(\d+));/) {

[download]
with: 
if (/^\t*MSISDN=(\d+);/) {

[download]
and use $1 rather than $2.
