=head1 NAME
xml2yaml - convert an XML message with a schema into YAML
=head1 SYNOPSIS
xml2yaml xml-file schema-file(s) >yaml-file
xml2yaml -x xml-file -s schema-files -o yaml-file
=head1 DESCRIPTION
Convert an XML message into YAML with the same structure. A schema
is required to enforce the correct syntax, especially for optionally
repeated elements.
=head2 Options
You can either specify an XML message filename and one or more
schema filenames as arguments, or use the options.
=over 4
=item --xml|-x filename
The file which contains the xml message. A single dash means "stdin".
=item --schema|-s filename(s)
This option can be repeated, or the filenames separated by comma's, if
you have more than one schema file to parse. All imported and included
schema components have to be provided explicitly.
=item --bigints|-b (boolean)
By default, the translation is a little sloppy: Integer types are defined
to support at least 18 digits in XML. However, this is usually unneccesary
large and unreadible in YAML.
=item --mixed HOW
[1.32] How to treat mixed elements. The default is TEXTUAL. Other values
are C<ATTRIBUTES>, C<XML_STRING>, and C<STRUCTURAL>. More details
about mixed_elements in XML::Compile::Translate::Reader.
=item --type|-t TYPE
The type of the root element, required if the XML is not namespaceo
qualified, although the schema is. If not specified, the root element
is automatically inspected.
The TYPE notation is C<{namespace}localname>. Be warned to use quoting
on the UNIX command-line, because curly braces have a special meaning
for the shell.
=item --output|-o filename
By default (or when the filename is a dash), the output is printed to stdout.
