Validating XML with its DTD in JSP

Is there a way to validate an XML file with its DTD, using a JSP ???
If YES, then HOW???
I hope my question is clear enough.
Please help!!

Thanks "Jleech",
I am using a textarea in a JSP to input for an XML file. The JSP transfers the file to Web-Server, which also has XERCES installed. My question is how can u Validate this transfered XML file with its DTD. My problem is I don't to how to include that Validation program in JSP.?
Could you still help???

Validating XML with external dtd without doctype specified in xml

Hi,
I am very new to SAX, DOM and things..but I am really pulling my hair to find the soln., I have tried to search soln but I found many people asking same question but hardly anyone was satisfactory.
My problem is that I have xml file without doctype specified in it, but I have dtd available on my system.
I have tried to set MyEntityResolver which implements EntityResolver in documentBuilder but its only getting called (resolveEntity method of MyEntirtyResolver), only when I add doctype to the xml (which is not what I want) and not when there is no doctype in the xml. I have set "factory.setValidating(true)" and I also have errorHandler in place.
But why EntityResolver is not invoked when its needed most. ie. when doctype is not available in xml ?...it complains that DOCTYPE must match root=null , which is obvious because no DOCTYPE in xml.
code is as follows:
please help me ..if anyone has any idea about this ....
Main class is :
public static void main(String args[]){
          Document document=null;
          ErrorHandler defaultHandler=new MyDefaultHandler();
          String xmlFile="note.xml";
          try{
               System.out.println("Starting...");
             boolean validXML = true;
             DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
             factory.setNamespaceAware(true);
             factory.setValidating(true);
             try {
                ExternalResolver er = new ExternalResolver();
// addURL is just a method which sets string in a map to be retrieved by resolveEntiy
                er.addURL("D:\\SAXnDOM\\SAXProject\\note.dtd");
                DocumentBuilder builder = factory.newDocumentBuilder();
                 builder.setEntityResolver(er);
                 builder.setErrorHandler(new MyDefaultHandler());
                builder.parse(new File(xmlFile));
             resolveEntity of ExternalResolver is as follows:
public InputSource resolveEntity(String publicId, String systemId)
               throws SAXException, IOException {
           System.out.println("********resolvedEntity:" +publicId +" and "+systemId +"******");
         if ( urlMap != null && urlMap.get(systemId)!= null ){
             try {
                 return new InputSource(new FileReader(systemId));
             } catch (FileNotFoundException e) {
                 System.out.println("[ERROR] Unable to load entity reference: " + systemId );
         return null;
public void addURL(String filePath) throws MalformedURLException{
          addURL(new File(filePath).toURL());
     public void addURL(URL url) {
         if ( urlMap == null ){
             urlMap = new HashMap();
         urlMap.put(url, null);
     }

Its working.... its working ...
problem was in resolveEntity, that stupid if condition was removed like this:
public InputSource resolveEntity(String publicId, String systemId)
               throws SAXException, IOException {
           System.out.println("********resolvedEntity:" +publicId +" and "+systemId +"******");
            try {
                 return new InputSource("D:\\SAXnDOM\\SAXProject\\note.dtd");
             } catch (Exception e) {
                 System.out.println("[ERROR] Unable to load entity reference: " + systemId );
         return null;
     }Other change is (which I didnt like ) is that in my xml, I had written fake doctype like :
<?xml version="1.0"?>
<!DOCTYPE note SYSTEM "fakenote.dtd">
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
<Prashant>prdfjfdj</Prashant>
</note> in above code fakenote.dtd doesnt exist anywhere ..its just to bypass that doctype:null error.
So my guess is that EntityResolver overrides doctype in the xml and applies its own doctype (note.dtd in this case)
But new proble comes...what if i dont want to add any doctype ..not even fake in xml ?
Hope my stupid mistakes will find someone usefull..

Managing XMl with its metadata.

I have several XML files in my repository. They are using a registered schema, so are not stored as CLOB.
I made several views+indexes that shows some XML node values in RDBMS manner.
Now I need to manage my XML with their metadata (mostly ResExtra).
I read the doc, and it seems that the only way to reach metadatas is via the PATH_VIEW/RESOURCE_VIEW.
So if I want to use statements that provides both data+metadata, I will have to use the PATH_VIEW in my FROM clause and the EQUALS_PATH/UNDER_PATH in my WHERE clause. Is there another way to retrieve metadata, given
a XMLType?
Can I make indexes for those queries? ie. can I make indexes over the PATH_VIEW ?

                xmlDocumentObject.load('C:\\My.xml')
            function changeHandler()
           and for that we need to a import i.e #import "C:\WINDOWS\system32\msxml4.dll"
          here when i try to import "msxml4.dll" in Acrobat javascript (js) file, it is giving error, application exits.
           How can i import dll in Acrobat javascript to get some functionality, or if not

Error validating xml with xsd schema on JSDK 1.4

Hi All,
Asked to me do it a Web Service client in Java and validate its xml answer with an xsd file using 1.4 plataform.
I googled and I saw many samples to 1.5 plataform, and few samples to 1.4, but anyway I tried to do what they asked to me.

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;

Validating XML 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.

Hello Vinayak,
I'm kind of new to this but I thinik I saw what you're looking for in a program called Echo05 or Echo07 in chapter 5 of http://java.sun.com/j2ee/1.4/docs/tutorial/doc/index.html.
I think I was working on it Friday and basically you have to have your own DTD then when Echo echo's the output it will throw errors with vaugue messages about how messed up your DTD is.
Regards,
Bill

URGENT---Validating XML file against DTD

I have a XML & DTD file.I want to validate that xml file against the specified DTD without using any editor.Through program how can i validate?Pl. help me.It's URGENT.

Problem validating XML with XSD

Hi everyone. I have an xsd schema and I want to validate some XML doc with the schema using SAX parser.
The user make the xml and then upload it to the server.
I want to enable client side validation but, for security reasons, I want also to validate this document when it's uploaded to the server.
The schema called ContentSchema.xsd
<?xml version="1.0" encoding="ISO-8859-1" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
     targetNamespace="www.mysite.com/Content" xmlns="www.mysite.com/Content">
     <xs:element name="content">
          <xs:complexType>
A document produced by the client starts in this way:
<?xml version="1.0" encoding="UTF-8"?>
<p:content xmlns:p="www.mysite.com/Content" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="www.mysite.com/Content ContentSchema.xsd">
in this way users can validate the XML doc before uploading. If the XSD is in the same folder of the uploaded XML the validation is ok.
The problem is that, on the server, I've stored the xsd file in a folder and I want the SAX parser to use this xsd to validate the XML. Even I pass the complete URI of the file to the parser, it won't work:
SAXParserFactory spf = SAXParserFactory.newInstance();
          spf.setValidating(true);
          spf.setNamespaceAware(true);
          spf.setFeature("http://apache.org/xml/features/validation/schema",true);
          spf.setFeature("http://apache.org/xml/features/validation/schema-full-checking", true);
          SAXParser sp=spf.newSAXParser();
          sp.setProperty("http://apache.org/xml/properties/schema/external-schemaLocation", schemaURL );
I set the schemURL with setProperty method but it's like the parser is looking for the XSD in the URL declared in the XML doc and not in the URI I specify. Anyone can help me?
Thank you very much

You will have to associate the schema with the namespace, like in your xsi:schemaLocation attribute.
Try something like this:
sp.setProperty("http://apache.org/xml/properties/schema/external-schemaLocation", "www.mysite.com/Content "+schemaURL);

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) {
               // pass
          }Message was edited by:

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 {

IllegalArgumentException - error validating xml with schema

I'm trying to validate an XML document using the following:
JAXP 1.2
Xerces 1.4.4
JDK 1.4.1
The xml is valid and I can confirm it with XML Spy when I point it to the schema definition. But, I get an IllegalArgumentException when I try to do it in my class.
Here's the code...
public static final String JAXP_SCHEMA_LANGUAGE = "http://java.sun.com/xml/jaxp/properties/schemaLanguage";
public static final String W3C_XML_SCHEMA = "http://www.w3.org/2001/XMLSchema";
public static final String CIS_SCHEMA = "D:\\dev\\xml\\cis.xsd";
public static final String[] SCHEMAS = { W3C_XML_SCHEMA, CIS_SCHEMA };
private static DocumentBuilderFactory dbf;
private static DocumentBuilder db;
try {
     dbf.setNamespaceAware(true);
     dbf.setValidating(true);
     dbf.setAttribute(JAXP_SCHEMA_LANGUAGE, SCHEMAS);
} (catch ...) {
I get the following error:
java.lang.IllegalArgumentException: http://java.sun.com/xml/jaxp/properties/schemaLanguage
Any ideas?

When I tried this with Xerces SAX, I got---
org.xml.sax.SAXNotRecognizedException: http://java.sun.com/xml/jaxp/properties/schemaLanguage
Maybe Xerces has not implemented the schemaLanguage property.
I have been successfully using Xerces-dependent properties to do validation:
XMLReader parser = saxParser.getXMLReader();
parser.setFeature( "http://xml.org/sax/features/validation", true);
parser.setFeature( "http://xml.org/sax/features/namespaces", true);
parser.setFeature( "http://apache.org/xml/features/validation/schema", true);
parser.setFeature( "http://apache.org/xml/features/validation/schema-full-checking", true);
if (noNamespaceSchemaLocation!=null) {
parser.setProperty(
"http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",
noNamespaceSchemaLocation);
if (schemaLocation!=null) {
parser.setProperty(
"http://apache.org/xml/properties/schema/external-schemaLocation",
schemaLocation);
Also, as DrClap pointed out, for the schema location I use URIs.
Please let me know if you got the jaxp schemaLocation property to work and how you did it.

Loading XML with defined DTD

Hi all!
I create XML and DTD. All working fine when I open it in MS XMLNotepad.
But when I try to load my XML in validating mode I get error
Error opening external DTD 'ReportsDTD.dtd'.
I open my XML through class loader as resource stream and then load it from this stream.
In XML I have such string
<!DOCTYPE DEFINITIONS SYSTEM "ReportsDTD.dtd">
Both xml and dtd are located in same directory.
Can anybody explain me whats wrong?
Mike

Reading from a stream, the parser has no idea what the "current directory" is.
So, when you reference a relative URL like "ReportsDTD.dtd", this means to find the DTD in the "same directory" as the current XML document.
You need to properly set the Base URL of the original input stream so that the parser knows what the base directory is.
Or, alternatively you can use getResource on the Class object that returns a URL and that has embedded within it the correct base URL "directory" info to work correctly.
So, if I have a "foo.xml" file that references "foo.dtd" inside, I can use the following code:
import java.net.URL;
import oracle.xml.parser.v2.*;
public class Class1
public static void main(String[] a) throws Throwable {
Class1 c = new Class1();
URL u = c.getClass().getResource("foo.xml");
DOMParser p = new DOMParser();
p.parse(u);
p.getDocument().print(System.out);
public Class1() { }

Have you looked at this documentation, Transforming and Validating XMLType Data

Validating XML with PL/SQL parser

How can i validate a xml that is on a buffer with the grammar
stored in a BLOB column of o table? I'm using PL/SQL parser and
i can parse it correctly but i don't know how can i validate it
because my grammar is stored in DB.

You can't currently but this will be available in our next
