HTML::TreeBuilder
Hi, my problem: I am parsing a html page looking for table-tags. The Treebuilder has a look_down function: $tree-look_down(_tag,table);#lists all tables in the html $tree-look_down(_tag,table, width,170);#lists all tables in the html with width 170 However, how can I list all tables that have no attributes? Ie somehow listing tag attributes and checking that the @list == 0?

working with array references.
Hi list,
given an array reference in a hash, how can I append an item to the end of
that array? Or find the length so that I can assign it using $ref-[$n]
type notation?
I have tried various comboes...
$hash{$key} holds a reference to an array in the sample code presented.
*) push(@$hash{$key},$item);
# --- gives an error message, not a valid array for push
*) $hash{$key}-[scalar $hash{$key}]=$item;
#no good either
*) $hash{$key}-[scalar @$hash{$key}]=$item;
#no good
*) $hash{$key}-[scalar @{[$hash{$key}]}]=$item;
#no good either
The following notation turned out to work though...
my $r=$hash{$key};
my @l=@$r;
$hash{$key}-[scalar @l]=$item;
...but I dont like the idea of _having_ to use those extra lines of code
there, there should be a way to append an item to a list reference in
one single operation.

Hi list, what module should I use to browse file shares on our home LAN? I tried simply 'opendir(DIR,\\server\share)', also with escaped \'s, but it wouldnt do the trick. Searching for 'net'-modules yields 1000 answers, I will be greatfull for any pointers!
