XML::Compile::XOP - MTOM and XOP handler
# 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 => $xop_image); # returned XOPs in SOAP my ($answer, $trace, $xop) = $wsdl->call($operation)->(%data); print $_->string for @$xop; # See XML::Compile::XOP::Include
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 attachment 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 separately. 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.
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
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
-Option --Default hostname 'localhost' xmlmime_version XMIME11 xop_version XOP10
