Re^5: duplicate table with HTML::TreeBuilder look

"I am trying to loop through the array ref but I am can't to able to. Am I missing something?"

Your problem is looping through an arrayref!

An arrayref is a single scalar. In this case: "ARRAY(0x2ae4b40)".

You probably want to loop through the actual array (@tds), not the arrayref (\@tds).

This will output each element of @tds:

for my $td (@tds) {
    say $td;
}

If I try to loop through the @tds I still get arrayref. Code: `foreach my $td (@tds) { say $td; }` [download] Output: `ARRAY(0x2a70c90) ARRAY(0x2a705b8)` [download]	[reply] [d/l] [select]

That is because you are working with a two dimensional array. You are very close, you just need to further dereference the variable `$td` `foreach my $td (@tds) { say for @$td; }` [download] However ... what are you going to do with the results, which are bits of HTML stored as strings? You most likely need something more like this: Read more...

It is to extract the class tags with Warning and Error in a very, very long html report and print only the Warning/Errors. Extracting the values and dump them into array is something I had in mind, thanks a lot Jeff!! (And I don't know you can emulate range function!)	[reply]
