[Xml-compile] wsdl soap call fails with missing data in response

[Paul B. Henson]

I'm trying to use XML::Compile to access the API exposed by a content
management system via WSDL based SOAP:

http://www.hannonhill.com/kb/Web-Services/web-services-operations/index.html

I think they publish the wsdl somewhere on their site, but I can't find
it at the moment, so a copy is at:

http://www.csupomona.edu/~henson/tmp/cascade-http.wsdl

I wrote a short test script that just calls the read method. The call
appears to successfully reach the soap server, but then the returned xml
fails to be parsed with the following error:

error: data for element or block starting with `success' missing at
{http://www.hannonhill.com/ws/ns/AssetOperationService}readResponse/readReturn

Honestly, xml gives me a headache :). I've spent a few hours working
with it and am at a bit of a loss. I dumped the returned xml, listed
at the bottom of this message, which to my eyes appears to contain
"<success>true</success>".

Any thoughts on what's going on? An error I'm making? A problem with
their wsdl file or soap server? I already beat my head against SOAP::WSDL
for most of yesterday with no luck. The release version didn't support
recursive data structures, and the development release failed with what
might be a similar error:

<Fault
xmlns="http://schemas.xmlsoap.org/soap/envelope/"><faultcode>SOAP-ENV:Server</faultcode><faultstring>Error
deserializing message: Can&apos;t call method &quot;get_class&quot; on
an undefined value at
/usr/lib64/perl5/vendor_perl/5.8.8/SOAP/WSDL/Expat/MessageParser.pm line
318.
 at line 2 at /usr/lib64/perl5/vendor_perl/5.8.8/SOAP/WSDL/Expat/Base.pm
 line 82

The examples the vendor provides are pretty limited, and only in java or
php. I'm not a big fan of php 8-/, and don't really want to use java for
what should be a simple scripting task.

Much thanks for any assistance. Here's the xml being returned that is
failing to parse:
