Hello,

I working with an application that stores the body of an e-mail within the "text" column (which is a binary datatype) of a SQL Server database table.

I'm using Matt's XML::Generator::DBI module and the DBD::ODBC driver to connect to the datasource. According to Matt's documentation he encodes binary data as Base64.

I need to convert this binary date (now Base64) back into the original e-mail message however, I'm not quite sure how to tackle the problem. Can anybody offer any help?

Here's a code sample showing how I connect to the datasource: 

# Instantiate a handle to the database.
use DBI;
my $dbh = DBI->connect("dbi:ODBC:$opt_hash{dsn}", $opt_hash{user}, $op
+t_hash{pass}, {LongTruncOk => 1}) 
   or die "Couldn't open database : '$DBI::errstr'; stopped";

# Instantiate the generator.
use XML::Generator::DBI;
my $generator = XML::Generator::DBI->new(RowElement => "Message", Hand
+ler => $builder, dbh => $dbh);

# Obtain a reference to the DOM.
my $dom = $generator->execute("exec $opt_hash{sp} \'$opt_dates{start}\
+', \'$opt_dates{end}\'");

# Print the result
print $dom->toString;

The XML output looks as follows: 
<Message>
 <ID>157</ID>
 <createdate>2002-05-21 09:39:16.343</createdate>
 <Subject>Msg4</Subject>
 <MessageBody>LCBJIGFtIHN0aWxsIHVuYWJ</MessageBody>
</Message>
