Personally, I'd use a hash. First, populate a hash of good node values
like this:
foreach (1, 2, 3, 4) { # Good node values
$goodNode{$_} = 1; # Set to "true"
}
Then for each node you find in the file, test against %goodNode:
if ($goodNode{$questionableNode}) { success }
Good Luck!

Subject: To read from a file using RegExp
I have a file as follows:
.SUBCKT JTJTAG Z@@793 Z@@753 Z@@109 Z@@86 Z@@15 Z@@296 Z@@61 Z@@207
Z@@135
+ Z@@275 Z@@313 Z@@1134 Z@@232 Z@@184 Z@@162 Z@@976 Z@@1014 Z@@253
+ Z@@954
Z@@39
+ Z@@138 Z@@622 Z@@1060 Z@@405 Z@@368 Z@@735
"Z@@xxx" stands for a node.
What I need to do is that read every node in the file and compare
everyone
with a given node to see whether it is in this file. What can I do
using
RegExp? Thanks:-)
