How to validate a XSD ?

[Ezeeckiel]

Hi !

I'm brand new in this wonderful love that xml is but i've got some troubles to create mty first xsd file. I've looked a lot on the internet and didn't really find THE example i need.

I try to validate it thanks to :

http://tools.decisionsoft.com/schemaValidate.html.

Here is the file :

My question is WAHT IS WRONG with it ?
Here are the errors the validator returns :

# Type reference '#IDType' is unresolved, locationURI: null, line: 1, column: 1, node: [xsd:attribute: null], annotationURI: null
# Type reference '#EntityType' is unresolved, locationURI: null, line: 1, column: 1, node: [xsd:attribute: null], annotationURI: null
# Type reference '#ListType' is unresolved, locationURI: null, line: 1, column: 1, node: [xsd:attribute: null], annotationURI: null
# Type reference '#TextType' is unresolved, locationURI: null, line: 1, column: 1, node: [xsd:attribute: null], annotationURI: null
# Type reference '#Frame_RangeType' is unresolved, locationURI: null, line: 1, column: 1, node: [xsd:attribute: null], annotationURI: null
# Type reference '#Keyframe_FrameType' is unresolved, locationURI: null, line: 1, column: 1, node: [xsd:attribute: null], annotationURI: null
# Type reference '#EntityType' is unresolved, locationURI: null, line: 1, column: 1, node: [xsd:attribute: null], annotationURI: null
# Type reference '#TextType' is unresolved, locationURI: null, line: 1, column: 1, node: [xsd:attribute: null], annotationURI: null
# Type reference '#Frame_RangeType' is unresolved, locationURI: null, line: 1, column: 1, node: [xsd:attribute: null], annotationURI: null
# Type reference '#Keyframe_FrameType' is unresolved, locationURI: null, line: 1, column: 1, node: [xsd:attribute: null], annotationURI: null
# Type reference '#Bounding_BoxType' is unresolved, locationURI: null, line: 1, column: 1, node: [xsd:attribute: null], annotationURI: null
# Type reference '#CentroidType' is unresolved, locationURI: null, line ..... etc..

I loaded your document into XMLSpy, and it complained about this:

 <xsd:attributeGroup name="EventAttributes">
        <xsd:attribute name="Event_ID" type="IDType" use="required"/>

You're saying you have an attribute named "Event_ID" which is of type "IDType", but it can't find a definition for "IDType".

Yes, it's defined up top, but it still doesn't like it. I would just use xsd:string, since your IDType doesn't have any other restrictions on it.

Salut!

Thanks for your answer !
It made me understand that i missed something...
Could you either explain me how to define this IDType ? (i thought :
<xsd:simpleType name="IDType">
<xsd:restriction base="xsd:string">
</xsd:restriction>
</xsd:simpleType>

was the definition it needed )
You said that I should use only a xsd:string since there's no restrictions. I'm starting with this because it easier not to make mistakes with simple examples and it'll get more complicated very soon. That's why i'd like to keep this kind of declaration.

Now my question is : "how to define my own members ?"
(i'm not even sure my question is something i can ask, maybe it's just all wrong lol)

I wouldn't even try declaring my own types for something as simple as that.

Another problem may be that your type is geared towards use as an element, and you're trying to use it as an attrbute. I've defined my own types for elements, but never for attributes -- don't know if it's possible.

My advice is, you're already making it complicated.
