I need to check the attribute value "id" of "book" (root) element.

If "id" value ends with three zeros(id="******-000") then the another attribute "book-type" should be "book" otherwise it should be "chapter".

Here is my xml looks like:

<book id="201019894-000" book-type="book" xsi:noNamespaceSchemaLocation="schema.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<book-meta>
<title-group>...

Is there any possibilities to check the above conditions in Schema(xsd).

Please guide me..

Thanks

Can't be done in XSD 1.0.

In XSD 1.1 you can do this with an assertion such as

<xs:assert test="if (ends-with(@id, '-000') then @book-type='book' else @book-type='chapter'"/>
