What I need is to satisfy the condition of AC element(i.e. search for n="CCC", or any other value being search for), from there I then need to look in a similar fashion the AI element 'n=???' and/or 'set=???' conditions. This should then allow me to extract the text from the other tags between <ID> and </ID> tags.

That's what I'm really after plus the text between <Desc>???</Desc> starting from the just below the <AC> tag. The text between the <Desc>???</Desc> is quite important because that can be changed/amended

Also, is it possible to substitute "CCC" below with a variable e.g my $CCC = "CCC"
XML::Twig->new( twig_handlers => { 'AC@n=$CCC//AI' => sub { print $_->start_tag, "\n"; }->parsefile( "my.xml");

ID will always be direct children of AI
AI will always be direct children of AC
All of the above will always have a <Desc>???</Desc> below them describing what they're all about.

<World n="earth" >
  <Space n="XXX">
    <CL n="XXX">
      <Desc>CL desc</Desc>
      <Other/>
      <AC n="AAA" set="n">
        <Desc>AC AAA desc</Desc>
      
        <AI n="AAA" set="n">
          <Desc>AI AAA desc</Desc>
          <ID n="AAA" set="y">
            <Desc>AAA ID desc</Desc>
            <What>What AAA ID </What>
            <AR>ID_aaa</AR>
          </ID>
            
          <ID n="BBB" set="y">
            <Desc>BBB ID desc</Desc>
            <What>What BBB ID </What>
