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.

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.

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");
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 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

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.

Validating XML against XSD

Hi,
I would like to validate XML against XSD using SAX parser. Can any one help, where I can get information. I could get some information of XML validation against DTD. But could not get much information for XSD validation.
Which parser is good for validation against XSD? or shall I continue with SAX Parser?
Kumaravel

I use the "Summer 02 XML Pack" provided here at Sun, which is based on Xerces2 by Apache (http://xml.apache.org/xerces2-j/index.html). Actually with that, validation against schemas is pretty much like validation against DTDs, as long as the schema is referenced in your XML file and you switch on schema validation in the parser like
reader.setFeature("http://xml.org/sax/features/validation", true);
reader.setFeature("http://apache.org/xml/features/validation/schema", true);Xerces2 works both with DOM and SAX (I use SAX). You should browse Apache's website a bit. There's not too much information, but I guess it's enough to get started.

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:

I am wondering if there is a way to validate XML file without using .......

I am wondering if there is a way to validate XML file without using the <!DOCTYPE... but pass in the location of the schema/DTD file as a parameter to a validating method?
thanks

None that I know of. The only thing close is to use the EntityResolver interface where you can modify the location of the DTD file before it's being loaded and parsed, but that requires a <!DOCTYPE ...> in the XML file.
Good luck.

Validate XML with XSD Puntuaction Marks

Hello all,
I am trying to validate a XML document against a registered XML schema. The XML document contains punctuation marks (like ã, ç, õ) which cause the validation to fail. How to overcome this?
I suspect of the encoding format the XSD and XML documents are using, encoding=UTF-8, right?
Thank you,
Pedro.

Ok... just needed to change the enconding attribute of the XML document to the value of the parameter NLS_CHARACTERSET of my database.
Unnecessary post. :-o)

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));

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.

Hi Paul,
Thanks for the response.
In my case, I am the exact opposite.
I have all external clients (which are admittedly all controlled (as in not truly public)). They are using a mixture of C, C# and Delphi. And yes, in most cases they are manually constructing the XML soap requests/responses. Yuk. The Delhi crowd are the worst offenders.
I have been working on a soap handler to do the schema validation. As of today, I've got the handler getting the complete soap message. And a separate program validates the request against the Schema. The only ugly bit is that I have to keep a copy of the schema portion separate from the WSDL file. It is currently completely within the WSDL file and not a separate XSD file.
Weblogic, evidently supports schema validation of soap messages. I have not been able to find how, or even if, you can do this in websphere. So I think that my only path is the soap handler approach.
I have not seen anyone publish their work, so I've yet to see if it can be done.
Thanks for the reply.
