Just hacked this together, it only knows about standard tags which are named, and doesn't know about tag attributes, but it is working.

use Modern::Perl;

my $knownCmds = '(use|conf|qd)';

$_ = qq@
<html lang="<qd>action</qd>">
  <head>
    <title><conf>site_title</conf></title>
  </head>
  <body>

   some orphan text

   <use>actions/<qd>action</qd>/somefile.aXML</use>

   <b>orphan</b> <conf>a</conf>

  </body>
</html>

#any text before first knownCmd
