Hello,

I've just discovered BaseX and decided to make some experiments. One of them is, suppose I have several documents (data + schemas), something like this:

sys/core.xsd

<?xml version="1.0"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="urn:SYS-CORE" targetNamespace="urn:SYS-CORE">

<xs:attribute name="category" type="xs:normalizedString"/>

</xs:schema> 

lib/album.xsd

<?xml version="1.0"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:SYS-CORE ../sys/core.xsd" xmlns:sys="urn:SYS-CORE" xmlns="urn:LIB-ALBUM" targetNamespace="urn:LIB-ALBUM">

<xs:import namespace="urn:SYS-CORE"/>

<xs:element name="album">

<xs:complexType>

<xs:sequence>

<xs:element ref="title" minOccurs="1" maxOccurs="1"/>

</xs:sequence>

<xs:attribute ref="sys:category" use="required"/>

</xs:complexType>

</xs:element>

<xs:element name="title" type="xs:normalizedString"/>

</xs:schema>

 

usr/albums/album1.xml

<?xml version="1.0"?>

<album xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:LIB-ALBUM ../../lib/album.xsd" xmlns:sys="urn:SYS-CORE" sys:category="albums" xmlns="urn:LIB-ALBUM">

<title>Album #1</title>

</album>

I'm uploading these documents using a Python script (I'm using BaseXClient) preserving the file system hierarchy structure I defined above. If I open the documents in IntelliJ IDEA, I can be sure that the documents are valid (I mean, I don't see XSD validation errors), therefore I'm assuming they are valid by fact. However, if I'm trying to validate the XML documents on the BaseX side

session.execute('XQUERY for $doc in collection("%s") where fn:ends-with(fn:base-uri($doc), ".xml") return validate:xsd($doc)' % database)

I'm getting the following error

[bxerr:BXVA0001] Validation failed: 1:186: schema_reference.4: Failed to read schema document '../../lib/album.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

I'm wondering, what am I doing wrong trying to validate documents directly in BaseX? Can BaseX resolve absolute/relative paths in this case?

Thanks in advance!

P.S. Apologies if I made something wrong (wrong subject, mailing list, non text/plain email, etc), this is my first time sending an email to a mailing list.
