RE: [xsl] How to check an element's type against an XSD simpleType and skip that element if it does not conform to the simpleType?

But **bk:ISBN-type** is a simpleType defined in the XML Schema; so I have to
import the XML Schema:

    <xsl:import-schema namespace="http://www.books.org";
        schema-location="BookStore.xsd"/>

But then I am back to the problem of the XSLT processor insisting on
validating all of my XML document.

Is there a way to get access to the simpleType, ISBN-type, without importing
the XML Schema?

Can't you just not validate the input, then test within the stylesheet
as you are testing an atomic/simple type.

If the input hasn't been validated you can just get the text content of
the node and check

<xsl:if test=". castable as bk:ISBN-type">

Or of course you could more simply in this case not import the schema
and just check the regular expression directly in the stylesheet (then
it will work with non schema aware systems too)
