Re: HTTPAPI and Webservices

hi Robert,

Yes, I think you're right, Robert.  For example, if your XML currently 
looks like this:

  <myXML>Data</myXML>

then in a wrapped SOAP message it'd look something like this:

<soap:Envelope xmlns:soap="http://www.w3.org/2001/12/soap-envelope";
               xmlns:tns="urn:WellingtonRoyceXmlWrapper">
  <soap:Body>
    <tns:YourRequest>
      <tns:Data>&lt;myXML&gt;Data&lt;/myXML&gt;</tns:Data>
    </tns:YourRequest>
  </soap:Body>
</soap:Envelope>

Granted, I made up some of the names ("YourRequest", "Data", the TNS 
namespace) but that's the general idea.  The original XML is escaped 
into character entities and placed in a parameter of a SOAP message.

It shouldn't be hard to build this message in an RPG program, and send 
it via HTTPAPI. The hardest part will be escaping the existing XML data 
-- but it shouldn't be too bad.  If you can't figure it out, let me know.

When the output message is sent back, you can use HTTPAPI's XML parser 
to extract the original XML data -- it'll automatically "unescape" it 
for you.
