George_Sherston has asked for the wisdom of the Perl Monks concerning the following question:

I just swept aside the dense curtain of cobwebs over the entrance to my cell and looked round the room I used to know so well but which I haven't for so long.. and my eye lighted on the Name Space node which I indexed ages ago. I wrote a script then to update the index and it worked fine. But now when I run it I get

Prototype mismatch: sub main::head vs ($) at ns.pl line 6

I think this is an LWP::Simple prob... but it's a complete new one on me. Has something change when I was in my Rip Van Winkle sleep?

If any kind monk can put me straight I'd be most grateful, and doubly glad because then I could update the wretched index. The bit of the script that (I think) is breaking down is
#!/usr/bin/perl -w use strict; use lib '/home/httpd/lib'; use CGI qw/:standard :cgi-lib/; use LWP::Simple; my $text = get 'http://www.perlmonks.net/index.pl?node_id=110166'; my %names = (George_Sherston => 110166); while ($text =~ s#<a HREF="/index\.pl\?node_id=(\d+)">.+?</a><BR> by < +a HREF="/index\.pl\?node_id=(\d+)">(.+?)</a> on \w{3} \d{1,2}, \d{4} +at# #) { unless (defined $names{$3}) { $names{$3} = $1; } }
Many thanks - it's lovely to be back in the hallowed halls.
