Perl XML::Writer Module

[NOTE: I already announced this on the perl-xml mailing list, but I
realised that I should do so here as well.]

I needed this, so I wrote it this morning:

  http://www.megginson.com/Software/XML-Writer-0.1.tar.gz

(I've also sent an upload to CPAN, but it might take a while to
appear).  Here's a very simple synopsis:

  use XML::Writer;
  use IO;

  my $output = new IO::File(">output.xml");
  my $writer = new XML::Writer($output);

  $writer->startTag("greeting",
                    "class" => "simple");
  $writer->characters("Hello, world!");
  $writer->endTag("greeting");

  $writer->end();
  $output->close();

(You can also leave out the $output argument if you want to go
straight to STDOUT.)

By default, the module does a fair bit of well-formedness checking to
help you catch bugs in your Perl programs -- you can turn the checking 
off for production use if you like to live on the wild side.

Here are the errors that the module catches so far:

- Lack of a (top-level) document element, or multiple document elements.
- Unclosed start tags.
- Misplaced delimiters in the contents of processing instructions or
  comments.
- Misplaced or duplicate XML declaration(s).
- Misplaced or duplicate DOCTYPE declaration(s).
- Mismatch between the document type name in the DOCTYPE declaration and
  the name of the document element.
- Mismatched start and end tags.
- Attempts to insert character data outside the document element.
- Duplicate attributes with the same name.

Full POD documentation and a lot of test cases in test.pl are
included.


Enjoy!


David
