( #3333=superdoc: print w/ replies, xml ) Need Help??

For those interested, it can't handle

  • Numerical entities (decimal and hex).*
  • External entities (e.g. HTML's &eacute).*
  • Character decoding.**
  • UTF-16, UTF-32, UCS-2, UCS-4.**
  • CDATA.
  • Namespace prefixes. (They're included as part of the name.)***
  • Comments.
  • Identification of an element's namespace.***
  • XML validation (i.e. it allows some malformed XML).
  • (more? this wasn't a thorough analysis)

Up to you to decide if it fits your needs or not.

* — A post-processor could fix this if no entities were processed at all.

** — A pre-processor such as the following would fix this:

sub _predecode { my $enc; if ( $_[0] =~ /^\xEF\xBB\xBF/ ) { $enc = 'UTF-8'; } elsif ( $_[0] =~ /^\xFF\xFE/ ) { $enc = 'UTF-16le'; } elsif ( $_[0] =~ /^\xFE\xFF/ ) { $enc = 'UTF-16be'; } elsif (substr($_[0], 0, 100) =~ /^[^>]* encoding="([^"]+)"/) { $en +c = $1; } else { $enc = 'UTF-8'; } return decode($enc, $_[0], Encode::FB_CROAK | Encode::LEAVE_SRC); }

*** — A post-processor could fix this, but one wasn't supplied.

Update: Added pre-processor I had previously coded.
