XML VALIDATION WITH EXTERNAL DTD

I've the following problem:
I've stored a dtd into the xdb repository(with createresource function) and all seems work.
In this DTD i've declared some element and one entity in this way :
<!ENTITY emsp " " >
When i try to store or extract my xml (with sql extract function) i get :
ORA-19202 Error during xml processing
LPX-00217 : invalid character 8195 (\u2003)
I've to declare the entity in a different way ?
Thanks in advance
Giovanni

XML Validation with External XSD

Hi
I have a xml file having DTD declaration, but my requirment is to validate this xml file with External XSD not with DTD which is declared inside the file.

XML-Document with extern DTD

Hello!
How can the Oracle XML-Parser parse a XML-Document without the
XML-Declaration. There is no information about the Version and
the DTD in the XML-Document. Can I use an extern DTD?

Validating an XML document using external DTD?

Hi,
I want to validate an XML file using external DTD with SAX parser.
How can I validate an XML file with external DTD.
Thanks in Advance,
Mahendra

I dont think we can set a DTD file throug java while
parsing an XML.I've done it with an XML schema though. Can you use that instead? For schemas you do something like:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setAttribute( "http://java.sun.com/xml/jaxp/properties/schemaSource",
schemaUrl );where schemaUrl in this case would be something like file:///usr/local/whatever.xsd

XML Validation with multiple XSD files (referenced)

Hello,
I know that XML validation with version 7.1 is possible now. However I was provided with a set of XSD files that have references to each other and need to be placed in a hierachical file system order so that references can be resolved.
An element <xsl:include schemaLocation="../../baseSchemas/baseSchema.xsd" /> is used for example. How can I handle that for XSD validation in PI? Can I create the same folder structure or do I need to put all XSD files in one directory and change the import manually?
But most important question: Is it possible it all to use more than one XSD for schema validation?

Dear Florian,
I had encountered such case in a project.
I was given 3 files. One main file and 2 others called Schema1.xsd and Schema2.xsd.
This happens because your data type is not in single namespace, but is being referred across namespaces and software components.
I am assuming that you have read the How to Guide for XML validations on PI 7.1
Best way to do this quickly is as follows.
1. Enable XML validation at adapter engine in the sender agreement.
2. Post a message using HTTP post. (http://sappihttpclient.codeplex.com)
3. Check communication channel in runtime workbench. There will be an error saying which is missing at what path.
4. Create the path mentioned and place the file at that path.
5. Repeat steps 2,3,4 for all the files.
When you are done with this, you will get a proper validation error in case XML file is not correct. And remember to generate XSD from message type and not data type.
Regards,
Vikas

XML validation with DTD in java 1.5 not supporting

Hi,
I am facing a problem regarding validation of xml file with DTD tag in it.
I have disabled the parser through setValidating(false) method.
xml file is not parsed in JRE 1.5.but it is parsed in JRE 1.6.
Why this is showing such a behavior?
I have used xerces 2.9.0,xml-api.jar and other jar regarding XML api but still it is giving error.
please help me.
please provide a jar file name or its issue resolution in jre 1.5 or 1.4.

thanks for your prompt reply.
I required that it should be completely disabled in jre 1.5(jdk1.5 or 1.4).
I am using DOM Parsing.I have currently disabled with follwowing method,
builderFactory.setValidating(false);
builderFactory.setFeature("http://xml.org/sax/features/validation",
     false);
     builderFactory.setFeature("http://apache.org/xml/features/nonvalidating/load-dtd-grammar", false);
     builderFactory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd",false);
     builderFactory.setFeature("http://xml.org/sax/features/external-general-entities", false);
     builderFactory.setFeature("http://xml.org/sax/features/external-parameter-entities", false);
     factory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
in 1.6 it is working fine but I required that i have to disabled it.but it is giving a error in jre1.5.
Exception in thread "main" java.lang.AbstractMethodError: javax.xml.parsers.DocumentBuilderFactory.setFeature(Ljava/lang/String;Z)V
I just want to disable the parsing in jdk version 1.5 or 1.4

ORA-31020 when using XML with external DTD or entities

I'd like to parse XML documents against a modular DTD that references other DTDs. This works fine with Oracle 9i. But after upgrading to 11g, the parsing of XML-instances fails and DBMS_XMLPARSER.parseClob produces ORA-31020.
The same error occurs even if I simply try to store XML with a reference to an external DTD as xmltype:
SQL> select xmltype('<?xml version="1.0" encoding="iso-8859-1"?><!DOCTYPE ewl-artikel SYSTEM "http://www.foo.com/example.dtd"><test>123</test>') from dual;
ERROR:
ORA-31020: Der Vorgang ist nicht zulässig, Ursache: For security reasons, ftp
and http access over XDB repository is not allowed on server side
ORA-06512: in "SYS.XMLTYPE", Zeile 310
ORA-06512: in Zeile 1
How can I use external DTDs on remote servers in order to parse XML in an 11g database??? Any ideas for a workaround? Thanks in advance!

This is my PL/SQL validation procedure:
procedure validatexml (v_id in number default 0) is
PARSER DBMS_XMLPARSER.parser;
DTD_SOURCE clob;
DTD_DOCUMENT xmldom.DOMDocumentType;
XML_INSTANCE xmltype;
BEGIN
-- load DTD from XDB repository
SELECT httpuritype('http://example.foo.de/app1/DTD1.dtd').getclob() into DTD_SOURCE from dual;
-- load XML instance
select co_xml into XML_INSTANCE from tb_xmltab where co_id=v_id;
-- parse XML instance
PARSER := DBMS_XMLPARSER.newParser;
xmlparser.setValidationMode( PARSER , false);
xmlparser.parseDTDClob( PARSER , DTD_SOURCE , 'myfirstnode' );
DTD_DOCUMENT := xmlparser.getDoctype( PARSER );
xmlparser.setValidationMode( PARSER , true );
xmlparser.setDoctype( PARSER , DTD_DOCUMENT );
DBMS_XMLPARSER.parseClob( PARSER , v_xml );
DBMS_XMLPARSER.freeParser(PARSER);
htp.print('<P>XML instance succesfully validated!<P>');
end validatexml;

XML Validation with DTD... Urgent

Hi all,
I am using java 1.4
I have to validate the XML file with the external DTD.
Can anyone give me the code for that.
DTD should be external.
Thanks,
Vinayak.

If you are using Solaris , it has xml validation tool "xmllint", using this you can validate your xml against DTD.
try with "xmllint --help " to see all the option.

XML validation with DTD stored in String object

Does anyone know if this is plausible......
I am trying to validate some XML with a DTD... easy enough, right? The catch is that the dtd is NOT stored in a file somewhere and is also not declared in the XML to be validated. It is stored in a String object (as is the XML file to be validated).
To clarify - I want to do something like this... but not sure how to incorporate the DTD.
String dtd = // dtd definition here
String xml = // xml text here (no URI at the top)
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
DefaultHandler handler = new DefaultHandler(); // DTD handler??
parser.parse(new InputSource(new StringReader(xml.toString())), handler);any help would be greatly appreciated.
thanks in advance,
Terrance

I guess it makes the most sense to make the dtd local to the xml. Therefore I would only have one string with both the xml contents and dtd contents. That is how I am going to approach this unless I hear something different.

Validating XML against an external DTD

I've three questions concerning the validation of an XML file on Checkin:
1. Can the SimpleXMLParser validate an XML file against an external (internal) DTD.
2. How do I have to construct the !DOCTYPE Reference in my XML file for the parser to find my external DTD
3. Do I need to have a iFS type definition for my file to get it validated
null

Yes, DTD Validation is supported for 1.1
but its not supported on a Per document basis
or a per protocol basis.
There is a System wide Property called
IfsDefaultDTDValidation which if set to true
will turn on validation for the entire
system (all protocols)
In addition, there is also support for a validate option to be passed to the parser
(which is currently not exposed for 1.1 through the protocols) but a Custom Parser
or application can set the validate mode on.
The validate option setting takes preference
over the IfsDefaultDTDValidation setting

XML validation with DTD

Hi Team,
I want to validate the XML content with DTD refered in the XML. I have problem now is my DTD are present in a jar file. How do I need to set systemid to the input source so that it works.
<!DOCTYPE test SYSTEM "test.dtd">
SAXParserFactory factory = SAXParserFactory.newInstance();
factory.setValidating(true);
factory.setNamespaceAware(true);
inputSource.setSystemId("path");
SAXParser parser = factory.newSAXParser();
XMLReader reader = parser.getXMLReader();
reader.setErrorHandler(new XmlValidationErrorHandler());
reader.parse(inputSource);
Regards
Richard

i believe the best way to handle that would be to set the EntityResolver on the XMLReader to your own implementation which loads the DTD from the jar.

XML validation with JDOM / JAXP

Hello,
I am trying to validate xml file against schema file. I decided to use JDOM and JAXP.
First question: is it a good choice?
I did a first attempt but not sure I have understood all what I am doing :(
First I have create a parser usinf org.jdom.*
SAXBuilder parser = new SAXBuilderThen I built my document:
Document doc = parser.build(myFile)These 2 steps are ok. But it does not do validation.
I saw in the JDOM documentation that I can set a validation flag to true. I did it. First problem, I got the following error from JDOMException: Document is invalid: no grammar found.
Is there a way to specify to the parser where to find the xsd file?
As I did not find answer to this question by myself, I tried implementing the Schema class from JAXP:
SAXBuilder parser = new SAXBuilder;
Document doc = parser.build(myFile);
Schema schema = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI).newSchema(schemaFile);
ValidatorHandler vh = schema.newValidatorHandler();
SAXOutputter so = new SAXOutputter(vh);
so.output(doc);It does the validation against the schema file specified but I am not really sure about what I am doing here. The last 2 commands are not clear to me :(
Then in my schema file, I have elements that have default value. I expected the following behavior: if the element is not in the xml file then the default will be used by the parser (and added in the tree). But it seems, it's not the case.
Any help/explanation will be really appreciated.

I am trying to validate xml file against schema file. I decided to use JDOM and JAXP.

If only schema validation is required use the validation API in JDK 5.0.
http://www-128.ibm.com/developerworks/xml/library/x-javaxmlvalidapi.html
http://java.sun.com/developer/technicalArticles/xml/validationxpath/
For validation with JDOM, the following validation application explains the procedure:import org.jdom.input.SAXBuilder;
import org.xml.sax.SAXException;import org.jdom.*;
import java.io.*;
public class JDOMValidator{
public void validateSchema(String SchemaUrl, String XmlDocumentUrl){
           try{
SAXBuilder saxBuilder = new SAXBuilder("org.apache.xerces.parsers.SAXParser",true);<br/>saxBuilder.setValidation(true);
saxBuilder.setFeature("http://apache.org/xml/features/validation/schema",true);
saxBuilder.setFeature("http://apache.org/xml/features/validation/schema-full-checking",true);
saxBuilder.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",SchemaUrl);
Validator handler=new Validator();
saxBuilder.setErrorHandler(handler);
saxBuilder.build(XmlDocumentUrl);
if(handler.validationError==true)
System.out.println("XML Document has Error:"+handler.validationError+""+
handler.saxParseException.getMessage());
else
      System.out.println("XML Document is valid");
          }catch(JDOMException jde){
            }catch(IOException ioe){
private class Validator extends DefaultHandler{
     public boolean validationError = false;
     public SAXParseException saxParseException=null;
public void error(SAXParseException exception) throws SAXException{
     validationError =true;
     saxParseException=exception;
public void fatalError(SAXParseException exception) throws SAXException {
validationError = true;
saxParseException=exception;
public void warning(SAXParseException exception) throws SAXException       {
public static void main(String[] argv)   {
   String SchemaUrl=argv[0];StringXmlDocumentUrl=argv[1];
   JDOMValidator validator=new JDOMValidator();
   validator.validateSchema(SchemaUrl,XmlDocumentUrl);

XML failing with Rosettanet DTD

Hi,
We are using a PIP5D5 xml message for an interface. This message is structurally defined as per the DTD provided in the Rosettanet standards. But for some segments where multiples are allowed, we are trying to use an attribute to distinguish each segment from other. (For Ex. <PartnerBusinessIdentification Type = "One">. )This new xml with attributes when verified against the dtd is failing with error, The element has no declaration for an attibute named 'Type'.
Is the usage of attributes invalid if you want to create a message as per Rosettanet standards? If so, how can we distinguish a segment when multiple occurences can be there?

XML Validation with no connection to the internet

Hi,
I'm trying to validate a ml instance document against a xml schema, using the javax.xml.validation.Validator.validate() method. This works fine as long as I have an internet connection, but not when I disconnect from the internet it fails.
I've detected, using a network sniffer, that this is due to the fact that the validation process tries to fetch the XMLSchema.dtd and datatypes.dtd from w3.org. Is there any way to avoid this by prestoring these somewhere? So that the internet connection is not needed?
I need to be able to do validation without a connection to the internet since the environment where my application is deployed does not have such a connection.
Ray

Hi Ray,
Were you able to resolve this issue? I am encountering a very similar problem where I am not connected to the internet and it fails during the newSchema method on javax.xml.validation.SchemaFactory. I have attempted to implement the suggestions of ExtremeGardener and vidyut with no luck.
Per ExtremeGardener's suggestion of replacing xmlns:xs="http://www.w3.org/2001/XMLSchema" with xmlns:xs="XMLSchema.xsd" and storing it locally, it gave me an error for trying to set the "xs" or "xsd" prefixes to anything other than "http://www.w3.org/2001/XMLSchema." I forget the exact error. I also tried to use my own prefix and it did not like that either.
Per vidyut's suggestion of using a catalog resolver, I believe that I have tried that too (if I understand correctly). I created an LSResourceResolver and tied it to the SchemaFactory. I can invoke it for a namespace but that did not resolve the issue because it only invokes the resolver on an import, include, or redefine. I believe that it is trying to reach the internet due to the xmlns:xs="http://www.w3.org/2001/XMLSchema" attribute within the top-level schema element in the XSD and I know of no way to invoke it for that.
I also created an ErrorHandler and tied it to the SchemaFactory. That shows me the errors and they are all related to the standard XML data types defined in XMLSchema.xsd. The errors that I am seeing are all of this form: "UndeclaredPrefix: Cannot resolve 'xs:string' as a QName: the prefix 'xs' is not declared."
I am currently using the SchemaFactory in Java 1.5, but I am thinking about trying the Xerces SchemaFactory since they are not exactly the same implementation.
Does anyone have any other suggestions? Any help you can provide would be greatly appreciated!
Thanks,
betzro1
