Validar schema xsd

Programação Java
#1

oi galera,

estou tentando validar um xml com um xsd. Mas já tentei de todas as formas e apresenta erro na validação como se a tag principal não existisse.

Segue minha classe q valida:

[code] public static void validaXSD() throws ParserConfigurationException, SAXException, IOException
{

         // Parse an XML document into a DOM tree.
         DocumentBuilder parser = DocumentBuilderFactory.newInstance().newDocumentBuilder();
         Document document = parser.parse(new File("cancelar.xml"));
         
         
         // Create a SchemaFactory capable of understanding WXS schemas.
         SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
         
         // Load a WXS schema, represented by a Schema instance.
         Source schemaFile = new StreamSource(new File("cancelar.xsd"));
         Schema schema = factory.newSchema(schemaFile);

         // Create a Validator object, which can be used to validate
         // an instance document.
         Validator validator = schema.newValidator();

         // Validate the DOM tree.
         validator.validate(new DOMSource(document));

         System.out.println("XML validado com sucesso");   

}[/code]

Se o xml q envio:

<?xml version="1.0" encoding="UTF-8"?> <CancelarNfseEnvio xmlns="http://www.abrasf.org.br/nfse.xsd" xmlns:ds="http://www.w3.org/2000/09/xmldsig#" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.abrasf.org.br/nfse.xsd ../xsd/nfse v2 0.xsd "> <Pedido> <InfPedidoCancelamento Id=""> <IdentificacaoNfse> <Numero>0</Numero> <CpfCnpj> <Cpf>Cpf</Cpf> </CpfCnpj> <InscricaoMunicipal>InscricaoMunicipal</InscricaoMunicipal> <CodigoMunicipio>0</CodigoMunicipio> </IdentificacaoNfse> <CodigoCancelamento>0</CodigoCancelamento> </InfPedidoCancelamento> <ds:Signature Id="idvalue0"> <ds:SignedInfo Id="idvalue1"> <ds:CanonicalizationMethod Algorithm="http://tempuri.org"/> <ds:SignatureMethod Algorithm="http://tempuri.org"> <ds:HMACOutputLength>0</ds:HMACOutputLength> </ds:SignatureMethod> <ds:Reference Id="idvalue2" Type="http://tempuri.org" URI="http://tempuri.org"> <ds:Transforms> <ds:Transform Algorithm="http://tempuri.org"/> </ds:Transforms> <ds:DigestMethod Algorithm="http://tempuri.org"/> <ds:DigestValue>MA==</ds:DigestValue> </ds:Reference> </ds:SignedInfo> <ds:SignatureValue Id="idvalue3">MA==</ds:SignatureValue> <ds:KeyInfo Id="idvalue4"> <ds:KeyName>ds:KeyName</ds:KeyName> </ds:KeyInfo> <ds:Object Encoding="http://tempuri.org" Id="idvalue5" MimeType=""> <ds:SPKIData> <ds:SPKISexp>MA==</ds:SPKISexp> </ds:SPKIData> </ds:Object> </ds:Signature> </Pedido> </CancelarNfseEnvio>

o erro que dá:

Exception in thread "main" org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'CancelarNfseEnvio'. at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(Unknown Source) at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.error(Unknown Source) at com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(Unknown Source) at com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(Unknown Source) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaValidator.handleStartElement(Unknown Source) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaValidator.startElement(Unknown Source) at com.sun.org.apache.xerces.internal.jaxp.validation.DOMValidatorHelper.beginNode(Unknown Source) at com.sun.org.apache.xerces.internal.jaxp.validation.DOMValidatorHelper.validate(Unknown Source) at com.sun.org.apache.xerces.internal.jaxp.validation.DOMValidatorHelper.validate(Unknown Source) at com.sun.org.apache.xerces.internal.jaxp.validation.ValidatorImpl.validate(Unknown Source) at javax.xml.validation.Validator.validate(Unknown Source)

reparem q no xml ta indo a tag. Mas ele fica apresentando erro como se não tivesse. Alguem sabe porque? :shock:

thank’s

já localizei que o erro está nessa linha:

Document document = parser.parse(new File("cancelar.xml"));

porque coloquei isso na linha abaixo pra ver se o parse está sendo feito:

System.out.println("xml parse: " + document.getTextContent());

e ele imprimi isso:

xml parse: null

agora porque ele não conseguiu fazer o parse…ta a duvida :?: :?: :shock:
