cvc-elt.1.a: Cannot find the declaration of element 'xxx'

Question

I have to handwriting an sample xml for my xsd, but I always get invalid message: cvc-elt.1.a: Cannot find the declaration of element 'RS_WMS_GET_PO_DATA_v2.0'.

My XSD:

<?xml version="1.0" encoding="utf-16"?>

My XML:

    <Parameters>

    </RS_WMS_GET_PO_DATA>
    <DMLAdapterConfig>
        <EnvironmentId></EnvironmentId>
    </DMLAdapterConfig>
</RS_WMS_GET_PO_DATA_v2.0>

Any ideas?

As because you did not mentioned which schema file to use for this XML file. I think tis will solve your problem.

Answer 2

I had an error

cvc-elt.1.a: Cannot find the declaration of element problem!

I solved it this way:

1. Look for your XSD file, if it has a xmlns attribute, for instance:

   xmlns="http://yourcompany/blablabla/rootElementName"
   

2. Look into your XML file, it must have an xmlns attribute if the XSD has defined one.

   <rootElement xmlns="http://company/xxxxxx/rootElementName">
   

3. XML is case sensitive. Review your XML tags and compare them with the XSD tags.
