Java – Ignore element order while validating XML against XSD

javaxmlxsd

We have an XML which needs to be validated against an XSD. The XML is being generated by XSTREAM. and We are using jaxp api's to validate the XML against the respective XSD. Unfortunately, currently our test case fail as the generated XML has elements/Tags in different order/sequence than the XSD.

Is it possible to ignore the order of elements in generated XML while validating it against XSD?

Thanks for the help in advance.

What you are asking for is a way to say "validate some of the XSD and ignore other parts". I don't think that can be done.

One possible solution would be to modify the schema so that instead of using a <sequence> for those elements (which requires that the elements be in a particular order) you can use <all>, which allows the elements to be in any order.

The point of a schema is to impose certain structure and requirements on an XML document. You can't just say "eh, I don't like that particular part of the schema, ignore it" as then the document doesn't conform to the schema anymore.

C# – Validating an XML against referenced XSD in C#

You need to create an XmlReaderSettings instance and pass that to your XmlReader when you create it. Then you can subscribe to the ValidationEventHandler in the settings to receive validation errors. Your code will end up looking like this:

using System.Xml;
using System.Xml.Schema;
using System.IO;

public class ValidXSD
{
    public static void Main()
    {

        // Set the validation settings.
        XmlReaderSettings settings = new XmlReaderSettings();
        settings.ValidationType = ValidationType.Schema;
        settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessInlineSchema;
        settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessSchemaLocation;
        settings.ValidationFlags |= XmlSchemaValidationFlags.ReportValidationWarnings;
        settings.ValidationEventHandler += new ValidationEventHandler(ValidationCallBack);

        // Create the XmlReader object.
        XmlReader reader = XmlReader.Create("inlineSchema.xml", settings);

        // Parse the file. 
        while (reader.Read()) ;

    }
    // Display any warnings or errors.
    private static void ValidationCallBack(object sender, ValidationEventArgs args)
    {
        if (args.Severity == XmlSeverityType.Warning)
            Console.WriteLine("\tWarning: Matching schema not found.  No validation occurred." + args.Message);
        else
            Console.WriteLine("\tValidation error: " + args.Message);

    }
}

Xml – Validating Signature element of XML fails against XSD

You have a couple of problems here:

The XSD says that

{mynamespace}Request must be the root element.
{mynamespace}Analysis must come before Signature
