XML::Rules: Can hierarchy be changed?

[hoppfrosch]

Hi, I've got a simple xml:

<root>
  <parent>p1 p2 <ch1>c1_1</ch1> p3 <ch2>c2</ch2> p4 <ch1>c1_2</ch1> p5
+</parent>
</root>

What I want to do is parsing this into a hash:

'root' => {
          'parent' => [
                      {
                        'text' => 'p1 p2 p3 p4 p5'
                        'ch2' => [
                                 'c2'
                               ],
                        'ch1' => [
                                 'c1_1',
                                 'c1_2'
                               ]
                      }
                      ]
          }

What I tried is (with XML::Rules):

my $parser =  XML::Rules->new (
  rules => [
    root => 'no content',
    parent => 'no content array',
    ch1 => 'content array',
    ch2 => 'content array',
    ]
);
my $result = $parser->parsestring($xml);

What I cannot figure out yet, is howto parse the "contents" of tag <parent> (I have to consider "p1 p2 "." p3 "." p4 "." p5" as content for some reason) into a child "text" of the item "parent" in my (desired) hash .... I tried several things like

# different Rule for "parent"
  parent => sub {$_[0]->{text} => $_[1]->{_content}},

but had no success yet ... (It's clear that above syntax does not make sense - but I think it expresses what I want to achieve)
Any help welcome!
