I'm using input.xsd schema file:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="Mobiles">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="Mobile" type="Mobile" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:complexType name="Mobile">
<xsd:sequence>
<xsd:element name="Model" type="xsd:string"/>
<xsd:element name="OS">
<xsd:simpleType>
<xsd:restriction base="xsd:string">
<xsd:enumeration value="Android"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="Origin" type="xsd:string"/>
<xsd:element name="Material" type="xsd:string"/>
<xsd:element name="Samsung" type="Samsung"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Samsung" mixed="true">
<xsd:sequence>
<xsd:element name="Wlan">
<xsd:simpleType>
<xsd:restriction base="xsd:string">
<xsd:enumeration value="802.11"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="CardSlot" type="xsd:string"/>
<xsd:element name="RadioAvailability" type="xsd:boolean" default="true"/>
<xsd:element name="BluetoothAvailability" type="xsd:boolean" default="false"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
And input.xml file looks like:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

I've followed this answer as example without namespaces for schema and this for better theoretical understanding.
But I'm always getting the issue locally in console when I'm trying to validate xsd schema file:
cvc-elt.1: Cannot find the declaration of element 'xsd:schema'.
org.xml.sax.SAXParseException; systemId: file:///F:/IdeaProject/TestProject/input.xsd; lineNumber: 2; columnNumber: 58; cvc-elt.1: Cannot find the declaration of element 'xsd:schema'.

using logic for validating like:
public void parse(boolean validate) throws ParserConfigurationException, SAXException, IOException {
System.out.println("Invoking parse()");
// obtain DOM parser
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
try{
dbf.setFeature("http://xml.org/sax/features/external-parameter-entities", false);
dbf.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);
dbf.setFeature("http://xml.org/sax/features/external-general-entities", false);
} catch(ParserConfigurationException exp){
logger.severe(MESSAGE);
logger.severe(Arrays.toString(exp.getStackTrace()));
}
// set properties for Factory
// XML document contains namespaces
dbf.setNamespaceAware(true);
// make parser validating
if (validate) {
// turn validation on
dbf.setFeature(Constants.FEATURE_TURN_VALIDATION_ON, true);
// turn on xsd validation
dbf.setFeature(Constants.FEATURE_TURN_SCHEMA_VALIDATION_ON, true);
}
DocumentBuilder db = dbf.newDocumentBuilder();
// set error handler
db.setErrorHandler(new DefaultHandler() {
@Override
public void error(SAXParseException e) throws SAXException {
// throw exception if XML document is NOT valid
throw e;
}
});
// parse XML document
Document document = db.parse(xmlFileName);
// get root element
Element root = document.getDocumentElement();
// create container
mobiles = new Mobiles();
// obtain mobiles nodes
NodeList mobileNodes = root
.getElementsByTagName(Names.MOBILE);
// process mobiles nodes
for (int j = 0; j < mobileNodes.getLength(); j++) {
Mobile question = getMobile(mobileNodes.item(j));
// add mobile to container
mobiles.getMobileList().add(question);
}
}
I've checked similar questions, for example, this one, but I don't have different uri http and https.
Also I've checked this answer, but I can't use any third-party dependencies for gradle project because of implementation restrictions (only if it's not the only solution).
CoreFiling XML Schema Validator reports about XML Schema & XML Instance:
XML instance present.
XML schema present.
and
Well Formed: VALID
Schema Validation: VALID
I can provide more information if needed. Can someone correct me, if I'm doing something wrong? Thanks in advance.
The error,
cvc-elt.1: Cannot find the declaration of elementxsd:schemawithout namespaces?
commonly indicates a mistaken attempt to pass an XSD to a validator as the subject of the validation rather than passing the intended XML file.
In your case, make sure that xmlFileName is for an XML file, not an XSD.
On the other hand, if you actually want to validate the XSD itself, see
