Can't evaluate field Restriction in type *gowsdl.XSDAttribute

[tmlbl]

Getting the following error on Windows and Linux:

genTypes error template: types:28:55: 
executing "Attributes" at <.Restriction.Base>: 
can't evaluate field Restriction in type *gowsdl.XSDAttribute

To reproduce run:

 gowsdl https://www.onvif.org/onvif/ver10/device/wsdl/devicemgmt.wsdl

[tmlbl]

Part of the problem with the ONVIF specification is that gowsdl does not form the correct URL to fetch one of the includes, getting a 404, and no error is reported. I will submit a PR for that issue but the above error still persists.

Here is an example of one of the types which is not being handled and causing the template error.

It seems that this should result in []int32 but since it does not have a restriction like gowsdl is expecting, it ends up with a nil pointer for .Restriction

<xs:simpleType name="EAPMethodTypes">
	<xs:list itemType="xs:int"/>
</xs:simpleType>

I have the same problem, when gowsdl is trying to parse such xsd:

<xsd:attribute name="CC_IssuingCountryInd">
    <xsd:annotation>
        <xsd:documentation>Country where the Credit Card was issued.</xsd:documentation>
    </xsd:annotation>
</xsd:attribute>

There is no Restriction element...

🍀  genTypes error template: types:27:54: 
executing "Attributes" at <.SimpleType.Restrict...>: 
can't evaluate field Restriction in type *gowsdl.XSDSimpleType

[realmfoo]

gowsdl can't handle a reference to attribute definition:

	<xs:attribute ref="xmime:contentType" use="optional"/>

@smgladkovskiy default type of xsd:attribute is anyType. Should it be interface{} or string?

[smgladkovskiy]

@realmfoo take a look at this definition of attribute that I faced with:

<xsd:attribute name="AiportCode" use="optional">
    <xsd:annotation>
        <xsd:documentation>Airport city code.</xsd:documentation>
    </xsd:annotation>
    <xsd:simpleType>
        <xsd:restriction base="AirportCitySimpleType"/>
    </xsd:simpleType>
</xsd:attribute>

I think that it would be better if it would be an interface{}. What do you think?

[smgladkovskiy]

I can share xsd with such cases to test on. :)

[smgladkovskiy]

In my case, as i understand, gowsdl is trying to parse restriction for simpleType when it is no restriction element.

I'm a having a similar issue, except it seems the problem really is with simpleType restriction:

genTypes error template: types:30:54: executing "Attributes" at <.SimpleType.Restrict...>: can't evaluate field Restriction in type *gowsdl.XSDSimpleType

given this chunk from the .xsd file:
