>From HTML::Element doc,
    $h->postinsert($element_or_text...)
i suppose it means postinsert accept $element or text. and the insertion didn't yield 
any error
with text as parameter.and it looks much simpler/easier than the new_from_lol. 

using HTML::Element->new_from_lol (['tr', ['td', 'TEST']]) did lead to the correct 
html output.
but when i am not using 'TEST' directly in new_from_lol

$insert= <<TEST;
<tr><td>some more tags here</td></tr>
TEST
$h = HTML::Element->new_from_lol (['tr', ['td', $insert]]);
then do postinsert($h);

the tags in $insert still don't get decoded after output.

any idea?
