Ok, I had a practical need for this method, and I think the API I have
is quite useable... here is the POD for what I plan to upload soon:
=head3 $elem->hash_map(hash => \%h, to_attr => $attr, excluding =>
\...@excluded)
This method is designed to take a hashref and populate a series of
elements. For example:
<table>
<tr sclass="tr" class="alt" align="left" valign="top">
<td sid="people_id">1</td>
<td sid="phone">(877) 255-3239</td>
<td sid="password">*********</td>
</tr>
</table>
In the table above, there are several attributes named C<sid>. If we
have a hashref whose keys are the same:
my %data = (people_id => 888, phone => '444-4444', password =>
'dont-you-dare-render');
Then a single API call allows us to populate the HTML while excluding
those ones we dont:
$tree->hash_map(hash => \%data, to_attr => 'sid', excluding =>
['password']);
Of course, the other way to prevent rendering some of the hash mapping
is to not give that element the attr
you plan to use for hash mapping.
