TreeBuilder Get embedded nodes - html

Question

Basically, I need to get the names and emails from all of these people in the HTML code.
<thead>
<tr>
<th scope="col" class="rgHeader" style="text-align:center;">Name</th><th scope="col" class="rgHeader" style="text-align:center;">Email Address</th><th scope="col" class="rgHeader" style="text-align:center;">School Phone</th>
</tr>
</thead><tbody>
<tr class="rgRow" id="ctl00_ContentPlaceHolder1_rg_People_ctl00__0">
<td>
Michael Bowen
</td><td>mbowen#cpcisd.net</td><td>903-488-3671 ext3200</td>
</tr><tr class="rgAltRow" id="ctl00_ContentPlaceHolder1_rg_People_ctl00__1">
<td>
Christian Calixto
</td><td>calixtoc#cpcisd.net</td><td>903-488-3671 x 3430</td>
</tr><tr class="rgRow" id="ctl00_ContentPlaceHolder1_rg_People_ctl00__2">
<td>
Rachel Claxton
</td><td>claxtonr#cpcisd.net</td><td>903-488-3671 x 3450</td>
</tr>
</tbody>
</table><input id="ctl00_ContentPlaceHolder1_rg_People_ClientState" name="ctl00_ContentPlaceHolder1_rg_People_ClientState" type="hidden" autocomplete="off"> </div>

I know how to use treebuilder with the nodes and such, and I'm using this code in some of my script.
my ($file) = #_;
my $html = path($file)-> slurp;
my $tree = HTML::TreeBuilder->new_from_content($html);
my #nodes = $tree->look_down(_tag => 'input');
my $val;
foreach my $node (#nodes) {
$val = $node->look_down('name', qr/\$txt_Website/)->attr('value');
}
return $val;
I was going to use the same code for this function, but I realized that I don't have much to search for, since the <td> tag is in so many other places in the script. I'm sure there's a better way to approach this problem, but I can't seem to find it.

Note: I did look on google as much as possible, but I'm not quite sure what I should search for.

Answer 1

The table element that encloses the data you need has a unique class rgMasterTable so you can search for that in look_down
I've written this to demonstrate. It pulls the HTML directly from your pastebin
use strict;
use warnings 'all';
use LWP::Simple 'get';
use HTML::TreeBuilder;
use constant URL => 'http://pastebin.com/raw/qLwu80ZW';
my $tree = HTML::TreeBuilder->new_from_content(get URL);
my ($table) = $tree->look_down(_tag => 'table', class => 'rgMasterTable');
for my $tr ( $table->look_down(_tag => 'tr') ) {
next unless my #td = $tr->look_down(_tag => 'td');
my ($name, $email) = map { $_->as_trimmed_text } #td[0,1];
printf "%-17s %s\n", $name, $email;
}
output
