i suspected to be wrong there. thanks. Maybe that syntax (strats-with(name)..) is not available in XML::Twig, or, more probably i'm not able to get rid of:

  my @all = $twig->get_xpath ('/Root/Parent/child*');
  #gives:error in xpath expression...

  my @all = $twig->get_xpath ('/Root/*/*[starts-with(name(), "child")]
+');
  #also gives error in xpath expression..

  #someresults with the findnodes method..
[download]

XML::Twig docs says these methods are similar to the XML::LibXML method. Being probably 'similar' the key word.

Albeit, if someone is able...welcome!
