NAME

XML::Compile::XOP - MTOM and XOP handler

SYNOPSIS

# by default, XML::Compile encodes binary data
my $answer    = $call->(image => $binary_image);

# to enable use of MTOM
use XML::Compile::XOP;
my $xop       = XML::Compile::XOP->new;
my $xop_image = $xop->bytes($binary_image);
my $answer    = $call->(image => $xop_image);

DESCRIPTION

The SOAP Message Transmission Optimization Mechanism (MTOM) is designed for SOAP1.2, but also usable for SOAP1.1. It optimizes the transport of binary information (like images) which are part of the XML message: in stead of base64 encoding them adding 25% to the size of the data, these binaries are added as pure binary attachement to the SOAP message.

In the official specification, the XML message will be created first with the base64 representation of the data in it. Only at transmission, a preprocessor XOP (XML-binary Optimized Packaging) extracts those components to be send seperately. In Perl, we have to be more careful about performance. Therefore, the path via encoding to base64 and then decoding it back to binary in the sender (and the reverse process for the receiver) is avoided.

METHODS

Constructors

$obj->bytes((STRING|SCALAR), OPTIONS)

    Create a XML::Compile::XOP::Include object which sources from a STRING (representing bytes) or a SCALAR reference to such a string. With the OPTIONS, you can overrule defaults generated for the "Include" object.

    example: use of bytes()

    my $data = $xop->bytes($string, type => 'text/html');
# $data is a XML::Compile::XOP::Include

$obj->file((FILENAME|FILEHANDLE), OPTIONS)

    Create a XML::Compile::XOP::Include object which sources from a FILE specified by NAME or HANDLE. With the OPTIONS, you can overrule defaults generated for the "Include" object.

    example: use of file()

    use MIME::Types;
my $mimetypes = MIME::Types->new;

my $type = $mimetypes->mimeTypeOf($fn);
my $data = $xop->file($fn, type => $fn);
# $data is a XML::Compile::XOP::Include

XML::Compile::XOP->new(OPTIONS)

    Option         --Default
hostname         'localhost'
xmlmime_version  XMIME11
xop_version      XOP10

    . hostname => STRING

      This is used as part of generated Content-IDs, which have the form of a email address.

    . xmlmime_version => URI

    . xop_version => URI
