Yes, normally you should be able to parse the transaction data. It has only been tested with a few blocks but normally everything can be red. It even recognises transaction scripts and tries to decompile them. For instance, it will see if the embedded data is pure ASCII text. That's how for instance the times headline can be explicitely seen when you read the genesis block.
So, assuming your transaction is in the binary string $tx, the following code should work, but you'll have to convert it into Bitcoin::DataStream first (I haven't made that automatic)
my $stream = new Bitcoin::DataStream $tx;
say +Dump Bitcoin::Transaction->new($stream);
I did use cryptographic libraries for digests, but I've found no perl library for ECDSA, and I've found using C libraries with XS or something much too complicated for me.
