OK. You haven't shown the other subs so I can't comment on what's happening there. But you said:

When i do a scaler on @errorlist i am able to get the exact number of elements in that array

So why do you not believe scalar() with @nodes? Do you not think that perhaps it is telling the truth and the array is empty?

Again, what is in @nodes right before you call scalar() on it? 

use Data::Dumper;
print Dumper \@nodes;

I can see that you check whether the array returned by reading the file is empty, and exit if so, but then you pass that data to getNodeAttributes() (not shown), and from that point on you don't test what you have before calling scalar @nodes.

The way forward always starts with a minimal test.
