XSD Restrictions based on target xml elements
Is it possible in xsd to create restriction based on elements of some type in target (processed) document?
For example I have XML like this:
<Pets>
<Pet name="Murka" />开发者_如何学Python
<Pet name="Browko" />
<Pet name="Tuzik" />
</Pets>
<Children>
<Child name="Petruk" favoritePet="Browko" />
</Children>
so what I want to restrict the attribute "favoritePet" of element "Child" based on existing "Pet" elements. How can I do this?
No, with the current XSD 1.0 specifications, you cannot do these kind of dependencies.
Should XSD 1.1 become a reality, then yes, that would support these kind of "assertions" - but I don't think anyone supports and uses XSD 1.1 at this time.
I found that "keyref" is an answer to my question :) It is solved now. Here is the resource.
