Validate XML against one DTD

Hello
I have several XML files and into this XML files there is not th DTD call.
i have another file, the DTD.
There is any method or code example for, without modify the XML files for including the DTD call, validate the XML againts one DTD?
thanks

The method to set the DTD is setDoctype().
Stub code follows:
// Test using InputSource
parser = new DOMParser();
parser.setErrorStream(System.out);
parser.showWarnings(true);
FileReader r = new FileReader(args[0]);
InputSource inSource = new InputSource(r);
inSource.setSystemId(createURL(args[0]).toString());
parser.parseDTD(inSource, args[1]);
dtd = (DTD)parser.getDoctype();
r = new FileReader(args[2]);
inSource = new InputSource(r);
inSource.setSystemId(createURL(args[2]).toString());
parser.setDoctype(dtd);
parser.setValidationMode(true);
parser.parse(inSource);
doc = (XMLDocument)parser.getDocument();
doc.print(new PrintWriter(System.out));

How to validate XML against XSD and parse/save in one step using SAXParser?

How to validate XML against XSD and parse/save in one step using SAXParser?
I currently have an XML file and XSD. The XML file specifies the location of the XSD. In Java code I create a SAXParser with parameters indicating that it needs to validate the XML. However, SAXParser.parse does not validate the XML, but it does call my handler functions which save the elements/attributes in memory as it is read. On the other hand, XMLReader.parse does validate the XML against the XSD, but does not save the document in memory.
My code can call XMLReader.parse to validate the XML followed by SAXParser.parse to save the XML document in memory. But this sound inefficient. Besides, while a valid document is being parsed by XMLReader, it can be changed to be invalid and saved, and XMLReader.parse would be looking at the original file and would think that the file is OK, and then SAXParser.parse would parse the document without errors.

Have you looked at the XML DB FAQ thread (second post) in this forum? It has some examples for validating XML against schemas.

How to parse XML against XSD,DTD, etc.. locally (no internet connection) ?

i've searched on how to parse xml against xsd,dtd,etc.. without the needs of internet connection..

Thanks a lot Sir DrClap..
I tried to use and implement the org.w3c.dom.ls.LSResourceResolver Interface which is based on the SAX2 EntityResolver.
please give comments the way I implement it. Here's the code:
LSResourceResolver Implementation
import org.w3c.dom.ls.LSInput;
import org.w3c.dom.ls.LSResourceResolver;
import abc.xml.XsdConstant.Path.DTD;
import abc.xml.XsdConstant.Path.XSD;
public class LSResourceResolverImpl implements LSResourceResolver {
     public LSResourceResolverImpl() {
      * {@inheritDoc}
     @Override
     public LSInput resolveResource(String type, String namespaceURI, String publicId, String systemId, String baseURI) {
          ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
          LSInput input = new LSInputImpl(publicId, systemId, baseURI);
          if ("http://www.w3.org/2001/xml.xsd".equals(systemId)) {
               input.setByteStream(classLoader.getResourceAsStream(XSD.XML));
          } else if (XsdConstant.PUBLIC_ID_XMLSCHEMA.equals(publicId)) {
               input.setByteStream(classLoader.getResourceAsStream(DTD.XML_SCHEMA));
          } else if (XsdConstant.PUBLIC_ID_DATATYPES.equals(publicId)) {
               input.setByteStream(classLoader.getResourceAsStream(DTD.DATATYPES));
          return input;
}I also implement org.w3c.dom.ls.LSInput
import java.io.InputStream;
import java.io.Reader;
import org.w3c.dom.ls.LSInput;
public class LSInputImpl implements LSInput {
     private String publicId;
     private String systemId;
     private String baseURI;
     private InputStream byteStream;
     private String stringData;
     public LSInputImpl(String publicId, String systemId, String baseURI) {
          super();
          this.publicId = publicId;
          this.systemId = systemId;
          this.baseURI = baseURI;
     //getters & setters
}Then, here's the usage/application:

How can i validate an xml against an dtd which are both in a clob ?

Hi,
I think my question says it all. I would like to validate
my xml which has been stored into a clob against a dtd
also stored in a clob. It has to be done with the xdk for plsql.

How to validate XML against Schema

Hi,
I am trying to validate the XML against the schema by using follywing code but i am never getting errors in parser it always passes the parser even though there are serious parsing problems. My code is as follows:
SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setNamespaceAware(true);
spf.setValidating(true);
SAXParser sp = spf.newSAXParser();
sp.setProperty("http://java.sun.com/xml/jaxp/properties/schemaLanguage",
"http://www.w3.org/2001/XMLSchema");
sp.setProperty("http://java.sun.com/xml/jaxp/properties/schemaSource", xsdPath);
DefaultHandler dh = new DefaultHandler();
sp.parse(splObjPath, dh);
thanks

Many ways to do this... also depending upon what version of Xerces and/or you want to do DTD or schema, etc one of the simplest is to set the following properties,
refer to:
http://xerces.apache.org/xerces2-j/features.html
Scroll down, check all the features starting with "http://apache.org/xml/features/validation"

Validate xml with local dtd

hello
trying to write a unit test that validates some xml we are marshalling against a dtd. here is a snippet of code. The problem is how to specify the dtd against which the xml is to be validated. verification_transaction is our root xml element. when i run this code i get a
malformedurlexception: no protocol: verification.dtd
any ideas?
                StringWriter writer = new StringWriter();
               // write the doctype declaration
                writer.write("<!DOCTYPE verification_transaction SYSTEM \"verification.dtd\">");
                // now marshal to the writer
          marshaller.marshal(spec, requestType, componentNumber, writer);
          InputStream inputStream = new ByteArrayInputStream(writer.getBuffer().toString().getBytes());
          Reader reader = new InputStreamReader(inputStream);
                // get a sax parser that is validating
          TestHandler handler = new TestHandler();
          SAXParserFactory factory = SAXParserFactory.newInstance();
          factory.setValidating(true);
          SAXParser saxParser = factory.newSAXParser();
          try {
               saxParser.parse(new InputSource(reader), handler);
               fail("Should have thrown exception.");
          } catch (RuntimeException e) {

I needed to do a bunch of things.
1.
                URL url = getClass().getResource("/verification.dtd");
          StringWriter writer = new StringWriter();
          writer.write("<?xml version=\"1.0\"?><!DOCTYPE verification_transaction SYSTEM \"" + url + "\">");and then I had to use a handler which processed the errors (which I got from an online tutorial):
private static class MyErrorHandler extends DefaultHandler {
          public void warning(SAXParseException e) throws SAXException {
               System.out.println("Warning: ");
               printInfo(e);
          public void error(SAXParseException e) throws SAXException {
               System.out.println("Error: ");
               printInfo(e);
               throw new SAXException("DTD Validation Error: [" + e.getMessage() + "]");
          public void fatalError(SAXParseException e) throws SAXException {

Validate XML against XML Shema while marshalling/Unmarshalling in JAXB?.

Hi,
Can i validate XML documents against XML Shema when i marshall/unmarshall the same using JAXB API?.
Thanks

Well, it is weird, but, the code below works when validating the NonEmptyString type:
XmlSchemaSet schemaSet = new XmlSchemaSet();
schemaSet.Add(null, "LogConfig.xsd");
XDocument doc1 = XDocument.Load("LogConfig.xml");
doc1.Validate(schemaSet, new ValidationEventHandler(ValidationCallBack), false);
However, if I leave the <LogName> empty it does not valid the values set on xsd fixed attribute,
The solution?
Well, I'm validating the same xml twice, the code above and the code on my first question.

How to Validate XML against XSD through PL/SQL?

Hi friends,
I m new to this forum. This is my first query.
In our project, we are trying to generate output XML using PL/SQL procedure. I have done that successfully. Now my problem is I have to validate this against our XSD. How will I do that? Can you provide me with a sample example.
Thanks to all in advance.
Regards,

Have you looked at the XML DB FAQ thread (second post) in this forum? It has some examples for validating XML against schemas.

HOW TO USE isSchemaValid() in oracle 9i to validate XML against XSD

Hi
I am trying to validate xml file against xsd in oracle 9i.The steps are as follows:
*1.Created directory for xml and xsd file location:*
CREATE or replace DIRECTORY XML_DATA AS 'D:\prod\sample xml and xsd;
*2.Register the schema*
DECLARE
bf5 BFILE;
BEGIN
-- Register the schema
dbms_lob.filecloseall;
bf5 := BFILENAME('XML_DATA','xml1.xsd');
DBMS_XMLSCHEMA.registerSchema('http://www.example.com/schemas/ipo.xsd',bf5,TRUE, TRUE, FALSE,TRUE,TRUE);
-- dbms_lob.fileclose(bf5);
END;
*3.creatibg table to store xml files*
CREATE TABLE po_tab2 (id NUMBER,xmlcol SYS.XMLType) ;
*4.Inserting xml file into the table and validating that file with xml schema*
declare
aa clob:=' ';
b varchar2(4000);
c xmltype;
begin
dbms_lob.filecloseall;
aa:= GETCLOBDOCUMENT('XML_DATA','example.XML','WE8MSWIN1252');
INSERT INTO po_tab2 (ID, XMLCOL)
VALUES
(104,sys.XMLType.createXML(aa));
commit;
--c:=sys.xmltype.createXml(aa);
c:=xmltype(aa);
b:=VerifyXML(c,'http://www.example.com/schemas/ipo.xsd');
dbms_output.put_line(b);
end;
_5.VerifyXML function is:_
create or replace
function VerifyXML( xml xmltype, xmlSchema varchar2 ) return varchar2 AUTHID DEFINER is
xmlURL varchar2(4000);
begin
select
s.qual_schema_url into xmlURL
from user_xml_schemas s
where s.schema_url = xmlSchema;
if xml.isSchemaValid(xmlURL,'ManageRolloutRegionNotification') =1 then
return( 'Valid. The supplied XML complies with XSD '||xmlURL );
else
-- return null;
return(sqlcode|| 'Failed. The supplied XML does not comply with XSD '||xmlURL );
end if;
exception when others then
return(sqlcode);
end;
_6.PROBLEM:_
the problem is the function is always returning 'Failed ' status even though I am giving the correct file.. Is there any method to find the reason for failure. These codes are working fine oracle 11g. currently i am working in 9i version 9.2.0.1.0. I

Oracle 9iR2 is not supported anymore.

I have two files: document.xml and rules.dtd. My "document.xml" does not reference "rules.dtd", but I would like to validate basead on this file. Is it possible?
Is there a method like: boolean isValid(String xmlFile, String dtdFile) ?
Thanks,

Validate XML against XSD with imported xsd's

Hello,
I'm stuck for a while attempting to validate a xml against some xsd's. In the code below you can find my xsd's structure: (I need to use this structure in order to reuse the baseXsd's files.

As you can probably notice, the <LogPath> key on the LogConfig is empty, but, it is defined as a NonEmptyString type. That is the way I'm validating the xml against xsd:
FileStream stream = new FileStream("LogConfig.xml", FileMode.Open);
XmlValidatingReader vr = new XmlValidatingReader(stream, XmlNodeType.Element, null);
vr.Schemas.Add(null, "LogConfig.xsd");
vr.ValidationType = ValidationType.Schema;
vr.ValidationEventHandler += new ValidationEventHandler(ValidationCallBack);
while (vr.Read()) ;
The validationCallBack is not being fired.
I suppose it is possible since the visual studio show me the error at compile time:

Well, it is weird, but, the code below works when validating the NonEmptyString type:
XmlSchemaSet schemaSet = new XmlSchemaSet();
schemaSet.Add(null, "LogConfig.xsd");
XDocument doc1 = XDocument.Load("LogConfig.xml");

Validate XML against XSD using PLSQL

Hi,
We now need some kind of automated solution that will pick
up the XMLs from a specific location or table and validate them
against the XSD in only Oracle PLSQL.
The validation of the XML against the XSD should take place when the XML is parsed.
I want to know how first the XSD's are stored or registered in the Oracle XDB repository.
Please can anyone suggest me how this can be done with a simple example
with a sample XML and XSD?
Regards,
Marlon.
