Hi
First, thanks for this great module!
I encountered a difference in the behavior of XML::Twig->simplify when
parsing empty elements with and without CDATA sections.
============================
Reproduce the bug
============================
When running the test script, with no options to simplify I get:
perl test.pl
$VAR1 = {
'foo' => 'something'
};
$VAR1 = {
'foo' => ''
};
$VAR1 = {
'foo' => 'something'
};
$VAR1 = {
'foo' => undef
};
but I was expecting
perl test.pl
$VAR1 = {
'foo' => 'something'
};
$VAR1 = {
'foo' => undef
};
$VAR1 = {
'foo' => 'something'
};
$VAR1 = {
'foo' => undef
};
or at least have the same behavior (either undef or '') when the
element is empty both with and without CDATA .
