I am attempting to use the Ruby SOAP library to automate interation
with the Horde framework (http://www.horde.org). I have discovered
that Horde has named all of its methods using an internal namespace
delimited with a '.' and this causes Ruby to break. I can see that
there is some code in the library that attempts to map the method names
with invalid characters to "safe" names but for some reason it's not
working completely. Ruby is not the only library to suffer this fault
either; so far Perl (SOAP::Lite) definitively has the same issue and
I'm beginning to think Python (SOAPpy) does as well.
I should mention that the WSDL generated by Horde looks to be entirely
valid and it's simply by convention that we don't see '.' in method
names. I believe this is why the issue still exists.
For testing purposes the WSDL that I am using can be found here:
http://mail-new.alkaloid.net/rpc.php?wsdl
And here is what Ruby says when it attempts to load the WSDL (this is
Ruby 1.8.4 with soap4r 1.5.5:
/usr/lib/ruby/1.8/soap/rpc/element.rb:269:in `check_elename': element
name 'horde.perms' not allowed (SOAP::RPC::MethodDefinitionError?)
from /usr/lib/ruby/1.8/soap/rpc/element.rb:238:in `initialize'
from /usr/lib/ruby/1.8/soap/rpc/proxy.rb:301:in `initialize'
from /usr/lib/ruby/1.8/soap/rpc/proxy.rb:87:in
`add_rpc_operation'
from /usr/lib/ruby/1.8/soap/rpc/driver.rb:154:in
`add_rpc_operation'
from /usr/lib/ruby/1.8/soap/wsdlDriver.rb:111:in
`add_operation'
from /usr/lib/ruby/1.8/xsd/namedelements.rb:58:in `each'
from /usr/lib/ruby/1.8/xsd/namedelements.rb:57:in `each'
from /usr/lib/ruby/1.8/soap/wsdlDriver.rb:96:in `add_operation'
from /usr/lib/ruby/1.8/soap/wsdlDriver.rb:40:in
`create_rpc_driver'
from test.rb:2
And the contents of test.rb:
$ cat test.rb
require "soap/wsdlDriver"
server =
SOAP::WSDLDriverFactory.new("http://mail-new.alkaloid.net/rpc.php?wsdl").create_rpc_driver
I'm not particularly good at reading W3C specifications, but from
what I'm reading it does appear to be valid for NCName to contain a '.'.
From the spec[1]:
is defined by the following pattern:
pattern = \i\c* ? [\i-[:]][\c-[:]]*
I'm not going to fully reconstruct that pattern but the '\c'
identifier is defined as the set of name characters matched by
"NameChar?"[2]. NameChar? is defined[3] as:
NameStartChar? | "-" | "." | [0-9] | #xB7 | [#x0300-#x036F | [#x203F-
#x2040]
I understand that to meant that a '.' is valid for an NCName. But I
may be misreading it and if so please correct me so I can take this
issue to the Horde developers for correction.
