WSDL parse failure (ruby 1.8.1-preview2, soap4r-1_5_1)

[Brian Marick]

The Ruby wsdl library doesn't seem to be able to parse the
GoogleSearch.wsdl file (http://api.google.com/GoogleSearch.wsdl).


I am using ruby 1.8.1-preview2. This problem happens both with the
pre-installed wsdl code and the code from soap4r-1_5_1.

Here's the symptom when I run the googleSearch/wsdlDriver example
from Soap4r:

Unknown attr {http://schemas.xmlsoap.org/wsdl/}arrayType.
Unknown attr {http://schemas.xmlsoap.org/wsdl/}arrayType.
/usr/local/lib/ruby/1.8/soap/encodingstyle/soapHandler.rb:396:in

from /usr/local/lib/ruby/1.8/soap/wsdlDriver.rb:301:in `rpc_send'
from (eval):2:in `doGoogleSearch'
from trial.rb:19

Those "Unknown attr" messages come from .../lib/ruby/wsdl/parser.rb in
decode_tag. A few puts's make me think that this part of the WSDL
provokes them:

<xsd:complexType name="ResultElementArray">
<xsd:complexContent>
<xsd:restriction base="soapenc:Array">
<xsd:attribute ref="soapenc:arrayType"
wsdl:arrayType="typens:ResultElement[]"/>
</xsd:restriction>
</xsd:complexContent>
</xsd:complexType>

<xsd:complexType name="DirectoryCategoryArray">
<xsd:complexContent>
<xsd:restriction base="soapenc:Array">
<xsd:attribute ref="soapenc:arrayType"
wsdl:arrayType="typensirectoryCategory[]"/>
</xsd:restriction>
</xsd:complexContent>
</xsd:complexType>

(I deduced this by printing out the name and attrs in
start_element. One element that seems to cause the error prints as:
xsd:attribute
wsdl:arrayTypetypensirectoryCategory[]refsoapenc:arrayType

Plus, the above two elements are the only ones that contain
"arrayType".)

Unfortunately, I am scandalously ignorant when it comes to SOAP and
WSDL and all that, so I'm not sure where to take this next. Can
someone offer a clue?

Hi,

The Ruby wsdl library doesn't seem to be able to parse the
GoogleSearch.wsdl file (http://api.google.com/GoogleSearch.wsdl).

Thank you for the report. My fault. I redefined "arrayType" in
wrong namespace in soap4r/1.5.1 (and I skipped Google WSDL test...)
For short-term workaround, try this patch to lib/wsdl/xmlSchema/data.rb
This definition should be moved to lib/wsdl/data.rb in the next release.
