NAME
XML::Handler::CanonXMLWriter - output XML in canonical XML format SYNOPSIS
use XML::Handler::CanonXMLWriter; $writer = XML::Handler::CanonXMLWriter OPTIONS; $parser->parse(Handler => $writer); DESCRIPTION
"XML::Handler::CanonXMLWriter" is a PerlSAX handler that will return a string or write a stream of canonical XML for an XML instance and it's content. "XML::Handler::CanonXMLWriter" objects hold the options used for writing the XML objects. Options can be supplied when the the object is created, $writer = new XML::Handler::CanonXMLWriter PrintComments => 1; or modified at any time before calling the parser's `"parse()"' method: $writer->{PrintComments} = 0; OPTIONS
IOHandle IOHandle contains a handle for writing the canonical XML to. If an IOHandle is not provided, the canonical XML string will be returned from `"parse()"'. PrintComments By default comments are not written to the output. Setting comment to a true value will include comments in the output. AUTHOR
