I'm not quite sure of your requirement but this may help:
sub startElement { my( $parseinst, $element, %attrs ) = @_; SWITCH: { # ... if ($element eq "step") { my $command = $attrs{command}; $command =~ s/\s+//g; # get rid of spaces if ($command eq 'LaunchApp') { MyModule::LaunchApp(%attrs); } elsif ($command eq 'Changemode') { MyModule::Changemode(%attrs); } # and so on for each command last SWITCH; } } } # This is your functions module package MyModule; sub LaunchApp { my %attrs = @_; print "\n----\nIn Sub MyModule::LaunchApp\n"; for my $attr (keys %attrs) { print "$attr: $attrs{$attr}\n"; } print "Leaving Sub MyModule::LaunchApp\n----\n"; } sub Changemode { my %attrs = @_; print "\n----\nIn Sub MyModule::Changemode\n"; for my $attr (keys %attrs) { print "$attr: $attrs{$attr}\n"; } print "Leaving Sub MyModule::Changemode\n----\n"; } 1;

[choroba]: hmm... so you need something like bag from Test::Deep, but not for checking, but for generation
[Corion]: This has the dual use of easily requesting sequential URLs and also being suitable for testing
[Corion]: For testing, I want to skip all tests with the same value(s) once one test fails to cut down on the number of failing tests
[Corion]: choroba: Yes, in a way I
[Corion]: ... I'm treating the incoming value sets as bags... Maybe I'll just put the burden on the user, at least in the first attempt at a full API. generate( headers => [{ 'Content-Type' => 'text/plain' }, {'Content-Type' => 'text/json' ] ), even ...
[Corion]: ... if that is cumbersome for the caller to specify. On the other hand, maybe there isn't that big a need for permuting the header values
