Question

I have an xml which is something like this:

<parent>
    <child>
        <value>Fixed value</value>
    </child>
    <child>
        <value>Any value</value>
    </child>
    <child>
        <value>Any value</value>
    </child>
    More children 
</parent>

How do I define a schema to check this? i.e. constrain some elements in a sequence of elements to have a child element of a given value. I currently get a warning that the schema is ambiguous.

Answer 1

This is not possible since – as the warning states – it makes the definition of the element ambiguous.

Xml schema doesn’t evaluate or validate the content or order of your Xml data, only the structure and data types.
