I am sure that the solution to this problem will be simple but it clearly eludes me at the moment. I'm writing out to two files, #1 = volcano and #2 = label.txt. I added the label routine so I could check on the whether the data was fresh or stale.

I'm getting an error,

"my" variable $outfile masks earlier declaration in same scope at ./vo
+lcano/volcano_parsing_2 line 14.</p> <p>
syntax error at ./volcano/volcano_parsing_2 line 14, near "open "
[download]

and it's not clear to me what Perl is really complaining about. I'm not declaring things twice.

Here's the full script:

#!/usr/bin/perl -w
use strict;
use warnings;
use XML::FeedPP;
use HTML::TreeBuilder::XPath;

# input
my $source = 'http://www.volcano.si.edu/news/WeeklyVolcanoRSS.xml';

# output
my $markers_dir = "/Users/coblem/xplanet/markers";
my $outfile = "$markers_dir/volcano";
my $labelfile = "$markers_dir/label.txt"
open my $fh,">",$outfile or die "$!";
open my $label, ">", $labelfile or die "$!";

# initialize
report_header();
my $volcano_color = "Chocolate";

label_header($markers_dir);
close $label;

# process

my $feed = XML::FeedPP->new( $source );

foreach my $volcano( $feed->get_item() ) {
  
  my $title   = $volcano->get('title');
  my $name    = substr($title, 0, index($title, '(', 0)-1);
  my $locn    = $volcano->get('georss:point');
    
  print $fh <<EOF

\# Title     : $title
\# Name      : $name
\# Location  : $locn
    
$locn "" color=Yellow symbolsize=4
$locn "" color=Orange symbolsize=8
$locn "$name" color=$volcano_color align=Below
   
EOF
}

close $fh;

sub report_header {
  my $cur_time = localtime;
  print $fh <<EOF
# This Volcano file created by script "volcano_parsing_1"
# Matt Coblentz; Perl version v5.12.4
# For more information, see the website $source
# Last Updated: $cur_time
  
EOF
}

sub label_header {
    my $update_time = localtime;

    print $label <<EOF
   -65 -1 "Volcano Infomation Last Updated $update_time" color=Green i
+mage=none position=pixel;
EOF

}

I will probably be embarrassed again about the error but I'm stumped!
