XML::Writer generates XML using an interface similar to CGI.pm. It
allows various checks to be performed on the document and takes care of
special caracter encoding.
Why use XML::Writer?
- you are generating XML documents "from scratch"
- you are used to CGI.pm
- XML::Writer is quite mature
Why NOT use XML::Writer?
- another method is more appropriate
- you don't like CGI.pm!
XML::AutoWriter both aim at emulating XML::Writer
- XML::ValidWriter performs some checks on the output document. Notably it
checks whether the elements and attributes are declared in the DTD and whether
you are closing the appropriate element.
- XML::AutoWriter automatically generates missing start or end tags, based
on the DTD.
XML::Handler::YAWriter are 2 other modules doing XML generation
At the moment XML::Writer seems to be the most mature and
efficient module to generate XML. Of course a lot of the
transformation modules such as XML::Simple, XML::DOM and
XML::Twig can also be used;
Of course plain print's can also be used, but I think
that XML::Writer is a lot more convenient and adds
some control over the generated XML.
my $doc = new IO::File(">doc.xml");
my $writer = new XML::Writer(OUTPUT => $doc);
$writer->startTag("doc", class => "simple"); # tag + att
$writer->dataElement( 'title', "Simple XML Document");# text elt
$writer->dataElement( 'title', "Introduction",
no => 1, type => "intro");
$writer->characters( "a text with");
$writer->dataElement( 'bold', "bold");
$writer->characters( " words.");
$writer->endTag(); # close section
$writer->endTag(); # close doc
$writer->end(); # check that the doc
# has only one element
$doc->close(); # fixed (was $output->close(); ) as suggested by the p
