Subject: Feature request: SOAP simpleType
Date: Mon, 19 Dec 2011 13:27:18 -0800

Hi, emacs!  I hope this is the right place to send feature requests.

I've been playing with Emacs 24's soap-client.el library, which is a
fantastic concept.

The "soap-load-wsdl-from-url" function seems to work in some cases,
but not in others.  I am certainly not an expert on SOAP or
soap-client but one thing that I've discovered is that it does not
seem to know about "simpleType".  (The term "simpleType" does not
appear in the source code.  The function soap-parse-schema looks at
only xsd:complexType and xsd:element.)

Here's an example of a WSDL that fails on a simpleType (called "AdultOption"):

    (soap-load-wsdl-from-url "http://api.search.live.net/search.wsdl")

Rather than parsing and returning a WSDL object, it gives a backtrace.
 Here's the top of it (the interesting part):

Debugger entered--Lisp error: (error
"Soap-wsdl-get((http://schemas.microsoft.com/LiveSearch/2008/03/Search
. AdultOption)): cannot find element")
  signal(error ("Soap-wsdl-get((http://schemas.microsoft.com/LiveSearch/2008/03/Search

[...and more...]

I've found that with my own application's WSDL, if I comment out all
uses of simpleType, then soap-client.el can load it just fine.

I have no idea how hard it would be to implement simpleType, but it
would definitely be very useful!  I may take a stab at this myself,
but no promises.

I have reported the issue at the soap-client's issue tracker:

Alex did accept the request. From the emacs-soap-client issue tracker:

Comment #1 on issue 9 by AlexHars...@gmail.com: Feature request: SOAP simpleType
http://code.google.com/p/emacs-soap-client/issues/detail?id=9

Thanks for reporting this, I will add simpleType to the list of
supported SOAP types.

Comment #2 on issue 9 by AlexHars...@gmail.com: Feature request: SOAP simpleType
http://code.google.com/p/emacs-soap-client/issues/detail?id=9

This issue was updated by revision a0ff70908303.

Added support for the simpleType and the WSDL at
http://api.search.live.net/search.wsdl loads without error.
Unfortunately it is not usable yet because the WSDL document defines two
entities with the same name: "SearchRequest" is both an xsd:element and
an xsd:complexType.  soap-client.el will need to be modified to account
for this possibility.

simpleType
http://code.google.com/p/emacs-soap-client/issues/detail?id=9

This issue was updated by revision 135e07156c5a.

I added a workaround for preventing simple self references, which works
with the WSDL from http://api.search.live.net/search.wsdl; It is unclear
to me what the correct/general solution would be.

Comment #4 on issue 9 by AlexHars...@gmail.com: Feature request: SOAP
simpleType
http://code.google.com/p/emacs-soap-client/issues/detail?id=9

The referenced WSDL now loads properly, but there is a bug in the
Emacs xml.el which prevents the response from the server to be parsed.
This has been reported as:

    http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10405

Also, the search API is not usable since it requires specifying an
"AppId" parameter, which need to be obtained first (this is outside
the scope of soap-client), see this link for details:

Finally, I have committed your patch to Emacs' trunk (it is reopened for
new features). Your xml patch found its way into Emacs 24.1.

Ken, could you, please, test whether this fixes your request?
