in reply to Convert MDB File To Txt File

There follows some old code that I had knocking around on my machine from a proof of concept.

This code was from a risk management project where there was a concern that the content of Access databases could not be analysed by the risk management search tool. The idea was to locate and dump any MDB to an XML file which could then be indexed without having to know anything about the database schema.

The code is probably well dodgy...

#! /usr/bin/perl -w # # Dump access databases to XML using DBI and DBD::ODBC use strict; use warnings; use File::Find; use DBI; use IO::File; use XML::Writer; use Cwd; #use Data::Dumper; my $findpath = $ARGV[0] ? $ARGV[0] : '.'; my $output; my $xmlwriter; my $driver = "Microsoft Access Driver (*.mdb)"; # scan all files looking for *.mdb find({ wanted => \&processDatabase}, $findpath); # Process MDB files # Produce and XML file in the same directory with the same name but xm +l extension. sub processDatabase { return unless $File::Find::name =~ /([^\/]*\.mdb)/i; my $database = cwd . "/$1"; my $xmlfile = $database; $database =~ s!/!\\!g; $xmlfile =~ s/\.mdb$/.xml/i; $output = new IO::File(">$xmlfile"); $xmlwriter = new XML::Writer(OUTPUT => $output, DATA_MODE => 1, DA +TA_INDENT => 4); $xmlwriter->xmlDecl("UTF-8"); $xmlwriter->startTag ("Database", "path"=>"$database"); exportDatabase ($database); $xmlwriter->endTag ("Database"); $xmlwriter->end(); $output->close(); } # Export the database sub exportDatabase { my $database = shift; print "Exporting: $database\n"; my $dsn = "dbi:ODBC:driver=$driver;dbq=$database"; my $dbh = DBI->connect("$dsn") or die "Couldn't open database: $DBI::errstr; stopped"; my $sth = $dbh->table_info( "", "", "", "TABLE" ); while ( my ($catalog, $schema, $table, $type) = $sth->fetchrow_arr +ay() ) { if ($table) { print "Exporting $table\n"; my $sql = "select * from $table"; # Prepare the SQL query for execution my $sth = $dbh->prepare ("$sql") or die "Couldn't prepare statement:$DBI::errstr; stopp +ed"; # Execute the query $sth->execute() or die "Couldn't execute statement: $DBI:: +errstr; stopped"; $xmlwriter->startTag ("Table", "name"=>"$table"); # Fetch each row and print it while ( my (@row) = $sth->fetchrow_array() ) { $xmlwriter->startTag ("Row"); foreach (@row) { $xmlwriter->dataElement ("Column", $_); } $xmlwriter->endTag ("Row"); } $xmlwriter->endTag ("Table"); } } # Disconnect from the database $dbh->disconnect(); }
