in thread Check for data in array

I'm not sure as I didn't write all this code. Most of it is taken from a Xymon sample.

Here is the peice of code that builds the Hash,

while ($line = <STDIN>) { if ($line =~ /^\@\@client\#/) { # It's the start of a new client message - the header +looks like this: # @@client#830759/HOSTNAME|1169985951.340108|10.60.65. +152|HOSTNAME|sunos|sunos # Grab the hostname field from the header @hdrfields = split(/\|/, $line); $hostname = $hdrfields[3]; # Clear the variables we use to store the message in $msgtxt = ""; %sections = (); } elsif ($line =~ /^\@\@/) { # End of a message. Do something with it. processmessage(); } elsif ($line =~ /^\[(.+)\]/) { # Start of new message section. $cursection = $1; $sections{ $cursection } = "\n"; } else { # Add another line to the entire message text variable +, # and the the current section. $msgtxt = $msgtxt . $line; $sections{ $cursection } = $sections{ $cursection } . +$line; } }

    Use Data::Dumper, try
    warn Dumper \%sections;
    before matching the regexp. With your sample data contained as string in the hash, everything should work.

      I've added warn Dumper \%sections; into my script and it still doesn't work. Any further ideas?

        Use Dumper as a debugging tool. What does it print to STDERR?
