Hi.
I am receiving XML documents from a number of different companies.
The documents I receive can contain a variety of different schema/dtd
declarations
eg
<!DOCTYPE OrderResponse SYSTEM "XCBL30.dtd">
<?soxtype
urn:x-commerceone:document:com:commerceone:XCBL30:XCBL30.sox$1.0?>
<Order xmlns="rrn:org.xcbl:schemas/xcbl/v3_0/xcbl30.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="rrn:org.xcbl:schemas/xcbl/v3_0/xcbl30.xsd Order.xsd">
or even no declaration at all.
I want to validate the documents that I receive against a xsd schema,
disregarding the declaration contained in the document.
I thought that I would be able to achieve this by writing my own
EntityResolver, and always resolve to a shema, however I have found that
this doesn't work.
It only works when a xsd schema declaration is passed.
For both sox schema declarations and no declaration I get :
ERROR-cvc-elt.1: Cannot find the declaration of element 'OrderResponse'.
before the resolveEntity method of the Entity Resolver is even called.
For dtd declaration I get : SAXException - The markup declarations
contained or pointed to by the document type declaration must be
well-formed. after the EntityResolver is called.
I am using the org.apache.xerces.parsers.SAXParser to perform the
validation.
SAXParser parser = new SAXParser();
parser.setProperty("http://apache.org/xml/properties/internal/grammar-pool";,
grammarCache);
parser.setFeature("http://xml.org/sax/features/validation";,
true);
parser.setFeature("http://apache.org/xml/features/validation/schema";,
true);
SchemaEntityResolver etyRes = new SchemaEntityResolver();
etyRes.setSchemaLocation(the_location);
etyRes.setFormat("XCBL");
etyRes.setVersion("30");
etyRes.setSchemaName(schemaName); // just sets the name of the
schema to use
ValidationHandler handler = new ValidationHandler();
parser.setErrorHandler(handler);
parser.setEntityResolver(etyRes);
StringReader stringReader = new StringReader(the_document);
InputSource inSource = new InputSource(stringReader);
parser.parse(inSource);
Does anyone know of any way I can force my document to be validated
against a schema.
Or do I have to manipulate the received document to remove the passed
declarations, and insert my own.
Thanks
