G'day Geert,

++ You're asking good questions. :-)

You've received a lot of good answers, so I won't delve into those again. However, I did want to say something about abstraction.

Whenever you have code with many lines that are almost identical, consider abstracting that code into one or more subroutines. Here's an example: 

my @inputpaths = @{test_paths([1..3])};
push @inputpaths, @{test_paths([4..7])};

sub test_paths {
    my ($ids) = @_;
    state $prefix = 'C:/Temp/xml/';
    return [ map "${prefix}test${_}.xml", @$ids ];
}

That code is intended to give you an idea of abstraction based on what you originally posted.

In other scenarios, you might want to pass $prefix as an argument to give you more flexibility; and, unless all your filenames look like testN.xml, you'd probably want to do something different than passing a list of numbers (to replace N). I'd also recommend you heed the advice of ++haukex regarding the use of modules such as File::Spec.
