Your program never reaches the my @node_list = $node->findvalues('td/tr')
due to the next
on the preceding line, so @node_list
never gets populated.
A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
