Validate XML using multiple XSD

(0) ShareShare
ReportReport
Posted on by Giuseppe Caradonna 1,421

Hi all,

I need to validate an XML file, that contains different XSD target namespaces, using a related XSD. I tried to merge XSD files and run the XMLReader class (method validate) passing the merged file but I received validation error (although the XML is correct).

Can anyone suggest me a way to validate my XML?

Thanks and regards,

Giuseppe

    Does it work elsewhere, e.g. if you run the validation in a XML editor? It seems more likely that your XSD file isn't correct rather than that XMLReader is broken.

    Hi,

    I have the same problem; I'm sure the XSDs are well formed and the XML file is valid, but the validation in AX fails.

    I have tried to validate the XML with:

    I have the XSDs like these:

    <!-- File1.xsd -->
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="www.w3.org/.../XMLSchema" xmlns:PMRQ="TargetNamespace2" xmlns="TargetNamespace1" targetNamespace="TargetNamespace1" elementFormDefault="qualified">
<xs:import namespace="TargetNamespace2" schemaLocation="File2.xsd"/>
<!-- XSD -->
</xs:schema>

    <!-- File2.xsd -->
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="www.w3.org/.../XMLSchema" xmlns="TargetNamespace2" xmlns:ns1="urn:CBI:xsd:CBISEDADReqLogMsg" targetNamespace="TargetNamespace2" elementFormDefault="qualified">
<!-- XSD -->
</xs:schema>

    <!-- File XML -->
<root xmlns:xsi="www.w3.org/.../XMLSchema-instance" xmlns="TargetNamespace1" xsi:schemaLocation="TargetNamespace1 File1.xsd">
<!-- ... -->
<ns2:Req xmlns:ns2="TargetNamespace1">
            <ns2:LogMsg>
                <ns3:GrpHdr xmlns:ns3="TargetNamespace2">
<!-- ... -->
</root>


    I tried to merge the XSDs into one and validate the XML with it (using http://www.utilities-online.info/xsdvalidation), but the validation still fails. The only way that i found to validate with success the XML is to edit the XML file like this:

    <!-- File XML -->
<root xmlns:xsi="www.w3.org/.../XMLSchema-instance" xmlns="TargetNamespace1" xsi:schemaLocation="TargetNamespace1 MergedFile.xsd">
<!-- ... -->
<ns2:Req xmlns:ns2="TargetNamespace1">
            <ns2:LogMsg>
                <ns3:GrpHdr xmlns:ns3="TargetNamespace1">
<!-- ... -->
</root>

    But, since I receive many XML files, I don't want to process each files in order to replace each attribute xmlns:nsX="TargetNamespace2" with xmlns:nsX="TargetNamespace1"


    Thanks and regards,

    Stefano

    Do I understand correctly that your merged XSD doesn't work anywhere and you test in Altova a .NET was actually about a different scenario?

    I really wouldn't expect MergedFile.xsd to get used if the schema location is set to a different file.

    I have successfully validated the XML with Altova and C# class using the two XSDs, but AX seems not work with this scenario, because the validation always fails.

    So I have tried to merge the xsd editing the File1.xsd by copying in it the definitions of the File2.xsd; the result was

    <!-- MergedFile.xsd -->
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="www.w3.org/.../XMLSchema" xmlns="TargetNamespace1" targetNamespace="TargetNamespace1" elementFormDefault="qualified">
<!-- <xs:import namespace="TargetNamespace2" schemaLocation="File2.xsd"/> -->
<!-- XSD -->
</xs:schema>

    Why I should not use the MergetFile.xsd? It does not work with the original XML, but after the edit, the MergedFile.xsd succesfully validates the XML ... I think the problem is related to the referenced targetNamespace inside the XML attributes; I'm wrong?

    If you have to replace one namespace to another to fulfil your schema, then your schema obviously doesn't match the file. If you don't want to change the file, you have to change the schema.

    Yes, it's true. So the question is: why Dynamics AX can't validate the original xml file using the two original XSDs?
    I've do this:

    Set                         permissionSet;
FileName                    xsdFile;
XMLReader                   xmlReader;
XMLSchema                   xmlSchema;

xsdFile = ".../myFolder/File1.xsd";
permissionSet =  new Set(Types::Class);
permissionSet.add(new FileIoPermission(xsdFile, #io_read));
permissionSet.add(new FileIoPermission((".../myFolder/File.xml", #io_read));
CodeAccessPermission::assertMultiple(permissionSet);

xmlSchema   = XmlSchema::newFile(xsdFile);
if(xmlSchema)
{
    xmlReader = XMLReader::newFile(".../myFolder/File.xml");

    try
    {
        validationError = xmlReader.validate(xmlSchema.writeToString());
    }
    catch
    {
        error("Error!");
    }
}

    The validate throws an error: Type 'TargetNamespace2' is not defined

    Why does this happens? The XSD file with the TargetNamespace2 is imported into the File1.xsd, used for the validation. The files (both XSDs and XML) are in the same folder.

    Could you give me sample files that I could use, without writing them by myself? The snippets above are not useful for this purpose.
