Cocoon2, SOAP: How to process xml-content?
I have a SOAP service which produces well formed xml-content. I want to
get data from that service into a cocoon xsp application. At the moment
the result looks like this:
[..]
<SOAP-ENV:Body>
<namesp3:list_allResponse xmlns:namesp3="urn:Stlist">
<s-gensym15 xsi:type="xsd:string"><?xml version="1.0"?>
<times>
<sdate>2002.01.07</sdate><stime>07:58:59</stime><edate>2002.01.07</edate><etime>12:01:49</etime><project>0099</project><brgroup>06</bgroup><comment>209
[..]
This is without processing any stylesheet.
My question is: How can I prohibit the xml-code to be converted to
text, or how can transform it back to xml to be processed by a
stylesheet later. The intention is to handle it like files with "xinclude".
Thanks,
Erwin

With real tags. Actually it's just a test module at the moment. But I've
found a solution right now.
Starting with the example:
http://cookbook.soaplite.com/#overriding%20serializer%20(server)
I wrote:
#----------------
package MySOAP;
use strict;
use vars qw(@ISA $VERSION);
use SOAP::Transport::HTTP;
use MySerializer;
@ISA = qw(SOAP::Transport::HTTP::Apache);
$VERSION = eval sprintf("%d.%s", q$Name: release-0_52-public $ =~
/-(\d+)_([\d_]+)/);
my $server = __PACKAGE__
-> new
-> serializer(MySerializer->new
-> autotype(0));
sub handler {
$server->configure(@_);
$server->SUPER::handler(@_);
}
1;
#----------
(I know, this is a big security hole, it will be secured next)
and:
#----------
package MySerializer;
@MySerializer::ISA = 'SOAP::Serializer';
sub envelope {
$_[2] = SOAP::Data->name($_[2])
->encodingStyle("http://xml.apache.org/xml-soap/literalxml")
if $_[1] =~ /^(?:method|response)$/;
shift->SUPER::envelope(@_);
}
1;
#----------
So the last trick was to create a new serializer with autotype(FALSE).
Now I have (with no transformer):
<SOAP-ENV:Envelope
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/1999/XMLSchema">
<SOAP-ENV:Body>
<list_allResponse
SOAP-ENV:encodingStyle="http://xml.apache.org/xml-soap/literalxml">
<s-gensym2>
<times>
<sdate>2002.01.07</sdate>
<stime>07:58:59</stime>
<edate>2002.01.07</edate>
<etime>12:01:49</etime>
<project>0099</project>
<bgroup>06</bgroup>
<comment>209
</comment>
</times>
[.. a lot more records ..]
</s-gensym2>
</list_allResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
I don't know, if this is completely correct, but it does now exactly
what I want. Thanks William, you brought me to the right direction.
Erwin
PS.:
For completeness, this is the part of the apache configuration for the
service:
<Location /mod_soap>
SetHandler perl-script
PerlHandler MySOAP
PerlSetVar dispatch_to "/usr/local/lib/site_perl,
/usr/share/perl/5.6.1, /usr/share/perl5, /usr/lib/perl5,
/usr/lib/perl/5.6.1, Module::Name, Module::method"
PerlSetVar options "compress_threshold => 10000"
</Location>

Your SOAP server appears to be converting XML tags to escaped form,
but thats exactly what you don't want. How is the data originally
stored, with real tags or in the escaped form.

Ok, I've got the service to write:
[..]
<SOAP-ENV:Body>
<list_allResponse
SOAP-ENV:encodingStyle="http://xml.apache.org/xml-soap/literalxml">
<s-gensym12 xsi:type="xsd:string"><?xml version="1.0"?>
[..]
But that does not change anything.
Let me ask another question: Is it possible to get the output of a
function handled as xml?
For example:
-------
[..]
<xsp:logic>
private String hello() {
return "<result>Hello</result>";
}
</xsp:logic>
[..]
<xsp:expr>hello()</xsp:expr>
-------
Will result the text node handled to the next transformer as it is shown
in the function and not as: <result>Hello</result> while the generated
java code looks like: return "<result>Hello</result>".

I don't have Java on the server. The soap service is made with Perl and
Apache::SOAP. So I hope I will find how to configure the service to
return an org.w3c.dom.Element, will I?

Why not have the service return a org.w3c.dom.Element -
that will produce xml directly in the SOAP response.
Your deployment descriptor would have an entry like this example I ran:
<isd:mappings>
<isd:map encodingStyle="http://xml.apache.org/xml-soap/literalxml"
xmlns:x="urn:ExercisePubs" qname="x:book-element"
javaType="org.w3c.dom.Element"
java2XMLClassName=
"org.apache.soap.encoding.literalxml.XMLParameterSerializer"
xml2JavaClassName=
"org.apache.soap.encoding.literalxml.XMLParameterSerializer"
/>
</isd:mappings>
