Question

I generated this xml file by marshalling it and then i want to unmarshall it by validating it to its schema. Why is this xml :

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ProjectConfiguration xmlns="http://ereg.egov.bg/segment/0009-900001">
    <CreationTime>2012-08-30T15:32:06.712+03:00</CreationTime>
    <Applications>
        <Application>
            <Version>1.0</Version>
            <CreationTime>2012-08-30T15:32:06.712+03:00</CreationTime>
            <FileName>ROSAppl-37</FileName>
        </Application>
    </Applications>
</ProjectConfiguration>

not a valid xml agains this schema:

<?xml version="1.0"?>
<xsd:schema 
targetNamespace="http://www.bulsi.bg/egov/ProjectConfiguration"
xmlns="http://www.bulsi.bg/egov/ProjectConfiguration"

            </xsd:annotation>

</xsd:complexType>

</xsd:schema>

This is the error : Cvc-elt.1.a: Cannot Find The Declaration Of Element ‘ProjectConfiguration’.. Line ‘2’, Column ’71’.

Answer 1

• Your Xml instance: xmlns="http://ereg.egov.bg/segment/0009-900001"
• Your Xml schema: targetNamespace="http://www.bulsi.bg/egov/ProjectConfiguration"

These URIs should match.

Otherwise, the <ProjectConfiguration> element from your Xml document will be assumed to belong to the http://ereg.egov.bg/segment/0009-900001 namespace, which is not defined in your schema.
