Not sure why you have the doctype declaration in there... perhaps your parser is missing XMLSchema.dtd?

In my xml.xsd there is no such declaration, I fetched it from https://www.w3.org/2001/xml.xsd

Betreff: [basex-talk] Problem with validate:xsd-report

Dear BaseX people,

I encounter a problem with validate:xsd-report(), more particular with using a schema importing the well-known xml.xsd. The imported attribute declaration (xml:base) is not found.

I am pretty sure that it is my fault, but I just can't find my error - could you take a look?

(1) Document: doc.xml

<book xml:base="/a/b/c"  

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="schema.xsd">

    <author>xyz</author>

</book>

(2) Schema: schema.xsd

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">

    <xs:import namespace="http://www.w3.org/XML/1998/namespace" schemaLocation="xml.xsd"/>

    <xs:element name="book">

        <xs:complexType>

            <xs:sequence>

                <xs:element name="author" type="xs:string"/>

            </xs:sequence>

            <xs:attribute ref="xml:base"/>

        </xs:complexType>

    </xs:element>

</xs:schema>

(In the same folder, a downloaded copy of xml.xsd is stored - for a snippet, see PS)

(3) Query: validate.xq

let $doc := 'doc.xml'

let $xsd := 'schema.xsd'

return validate:xsd-report($doc, $xsd)

(4) Result:

basex validate.xq

=>

<report>

  <status>invalid</status>

  <message level="Fatal" line="9" column="43" url="file:/C:/projects/d2type/jats/test-validation/schema.xsd">src-resolve: Cannot resolve the name 'xml:base' to a(n) 'attribute declaration' component.

  </message>

</report>

I do not understand why the import seems to be ignored. Validating with oXygen works fine, but I suppose that oXygen ignores the @schemaLocation.

If you see the reason, please let me know.

Cheers,

Hans-Jürgen
