XML Validation using XML Schema

[Philip Manual]

Hi All,

Is there a way to restrict the value of one xml element on the basis of another xml element's value ?

(e.g)
Valid values for Item = Type1, Type2, Type3
Valid values for SKU = Value1, Value2, Value3

If the value of Item is Type1, then the value of SKU should be Value1.

Valid XML
<XMLRoot>
<Item>Type1</Item>
<SKU>Value1</SKU>
</XMLRoot>

Invalid XML
<XMLRoot>
<Item>Type1</Item>
<SKU>Value2</SKU>
</XMLRoot>

Any help is appreciated.

Thanks
Philip

I have read this post a couple of days back and have been thinking about it and this is what I feel -

What you ask seems to be like creating a data construct with two primary keys. But, if you must, then I would guess that you will need to define a few complex types and define a sequence of two elements for that type.

I feel a better way of modelling this data would be to make one of the elements an attribute or even both of them as attributes say name, SKU.

Hi Madhav,

Thanks for your reply.
Based on the requirements, I cannot make them as attributes. The XML i gave in my original post was just an example. The actual XML is for registration purpose. A snippet of the XML would be

<UserType>A</UserType>
<Access>1</Access>

Designing them as Individual elements/tags instead of attributes, makes sure all valiation is done by the XML parser instead of validating these elements in code.

So, the workaround/solution I used for this issue is to create complexTypes for various valid combination (Just the way you mentioned). Luckily, I had just two combination.
