Error when using QXmlSchema and QXmlSchemaValidator

Ben35

Hello,

I have a concern using the validation of an XML file with an XML Schema file. I tried to reproduce the basic sample provided by the documentation, but I have an error.

Here is my XML Schema :

<?xml version="1.0" encoding="UTF-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element type="xs:string" name="toto">
  </xs:element>
</xs:schema>

And my XML file to validate :

<?xml version="1.0" encoding="UTF-8" ?>
<toto>titi</toto>

When I try to validate this couple of files using other validation tools (for example http://www.xmlvalidation.com/), it is a success.

But when I run this Qt code, I have an error :
Error XSDError in file:ArchiverConfiguration.xml, at line 2, column 6: No definition for element toto available.

bool isConfigurationFileValidAgainstSchema(const QString &filePath)
{
    // Retrieve the schema :
    QXmlSchema schema;
    schema.load(MY_XSD_URL);
    // The xsd resource file can't be invalid :
    assert(schema.isValid() && "The  file schema (.xsd) is invalid.");

    // Validate the user file :
    QFile file{filePath};
    file.open(QIODevice::ReadOnly);
    QXmlSchemaValidator validator{schema};
    auto ok = validator.validate(&file, QUrl::fromLocalFile(file.fileName()));
    return ok;
}

The error appears during the line :

auto ok = validator.validate(&file, QUrl::fromLocalFile(file.fileName()));

Would anyone have an idea of the problem?

Thank you,
Ben

Hi,

Are you running a debug or release version of your application ? If a release then your assert won't help diagnosing if something's wrong.

Hi, I think you're right. I'm in a release version. And indeed my schema seems to be invalid. Thanks.

You're welcome !
