If you solved your problem then you won't need this.
But, just in case you are interested in looking at it from a little
different view....
It is not a complete solution, just an idea.

inp = <<DATA
05Topic 5
1Topic 1
2.002.1Topic 2.2.1
2.1Topic 2.1
2.2.02Topic 2.2.2
DATA

err1 = inp.select{|a| a =~ /^0|\.0/}
puts "A number may not start with zero" unless err1.empty?
print err1
puts
err2 = inp.select{|b| b =~ /^\d+\.\d+\.\d/}
puts  "No more that two numbers may be prefixed" unless err2.empty?
print err2
