Re: HTML::TableExtract

OT for [EMAIL PROTECTED] - the answer is the same regardless of the OS 
you happen to be using. This would be more appropriate for a general 
Perl forum, perhaps comp.lang.perl.modules. Having said that...

Define "bombs". Do you get an error message? If so, what is it?
I would like to check to see if it matched, but I don't know what to 
check.  Can someone please help me.

    my $te = new HTML::TableExtract( headers => ["1 Year", "3 Year", 
"5 Year", "10 Year"] );
    $te->parse($html);
  >>  my $p  = ($te->rows)[0];
You're pretty much asking for errors here, by subscripting the return 
value from a method that might return an empty list. You should check 
it first:

my @table_rows = $te->rows();
if (@table_rows) {
    my ($one, $three, $five, $ten) = @{$table_rows[0]};
}
