Validate XML Document

Hi I was wondering how I could validate a document based on a hard coded string representing a dtd in my program. basically I have:
private static final String DTD = // dtd that the animation xml file must follow
            "<?xml version='1.0' encoding='utf-8'?>" +
            "<!ELEMENT animation (frame+)>" +
            "<!ELEMENT frame (#PCDATA)>" +
            "<!ATTLIST frame duration CDATA #REQUIRED>";
Document doc;doc has allready been filled with xml data:
DOMResult result = new DOMResult(doc);
StreamSource source = new StreamSource(zip.getInputStream(zip.getEntry("animation.xml")));
TransformerFactory tfactory = TransformerFactory.newInstance();
Transformer transformer = tfactory.newTransformer();
transformer.transform(source, result); // transform the animation.xml file into our domnow i simply want to validate the document against my hard coded dtd. Thanks :)

Add a <!DOCTYPE root_element SYSTEM "dtdFile.dtd"> to the xml document.

What is the correct way to validate xml documents in XDB?

Hi,
I'm having a problem validating documents stored in XDB.
The problem showed up while tracking down a bug whereby
Oracle appeared to store documents that weren't valid.
Section 8-6 of the 10g manual has the following:
"By default, the database checks to ensure that XMLType
instances are well-formed. ... Because full XML schema
validation (as specified by the W3C) is an expensive
operation, when XMLType instances are constructed, stored,
or retrieved, they are not also fully validated."
Bugger.
So I'm not trying to work out how to validate the
documents we already have stored in the database. I'm
using the following script to check a particular document:
---8<---
declare
doc xmltype;
begin
select extract(res, '/Resource/Contents/*') into doc from resource_view where any_path = '/home/cosmos/AnnualAllocation-1000000010000090.xml';
if doc.isSchemaBased() = 1 then
dbms_output.put_line('Schema based ...');
dbms_output.put_line('Schema URL:' + doc.getSchemaURL());
doc.schemaValidate();
else
dbms_output.put_line('Not schema based');
end if;
end;
---8<---
When I run the script, I get the message 'Not schema based',
which is confusing the heck out of me.
Here's the first couple of lines from that xml file:
---8<---
<AnnualAllocation
xmlns="http://digitalsteps.com/schema/cosmos"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://digitalsteps.com/schema/cosmos http://cosmos.com/schema/cosmos/AnnualAllocation.xsd"
id="AnnualAllocation-1000000010000090">
---8<---
So, these are the observations I've got so far:
1. The file is schema-based (schemaLocation is present
and correct); and
2. The schema is registed (schema url is present in
user_xml_schemas; AND document is stored in the default
table).
I can see no reason why the script doesn't report the xml
file are being schema-based.
Any ideas?

Ashim,
Try looking at the program:
CRM_TEST_ORDER_MAINTAIN
I think that should help you figure out the parameters.
Good luck,

Problem to validate XML document if the type of root element is abstract

I have the following XML document:
<?xml version="1.0" encoding="UTF-8"?>
<ct013/>
It corresponds to the following XSD Schema:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
     <xs:element name="ct013" type="foo"/>
     <xs:complexType abstract="true" name="foo"/>
     <xs:complexType name="fixedType">
          <xs:complexContent>
               <xs:restriction base="foo"/>
          </xs:complexContent>
     </xs:complexType>
</xs:schema>
Please take attention to the fact that the type of root element of that BDD is abstract.
XML Schema provides a mechanism to force substitution for a particular element or type. When an element or type is declared to be "abstract", it cannot be used in an instance document. When an element is declared to be abstract, a member of that element's substitution group must appear in the instance document. When an element's corresponding type definition is declared as abstract, all instances of that element must use xsi:type to indicate a derived type that is not abstract.
Declaring an element as abstract requires the use of a substitution group. Declaring a type as abstract simply requires the use of a type derived from it (and identified by the xsi:type attribute) in the instance document.
For more information of using abstract types please see chapter 4.7 Abstract Elements and Types of XML Schema Part 0: Primer Second (http://www.w3.org/TR/xmlschema-0/#abstract).
In this case there is Oracle bug when I try to validate this XML document using Oracle XDK:
String validate(String xml, String schema)
throws XSDException, XMLParseException, SAXException, IOException
System.setPropert("oracle.xml.parser.debugmode", "true");
XSDValidator xsdValidator = new XSDValidator();
XMLError xmlError = new XMLError();
xmlError.setErrorHandler(new DocErrorHandler());
XMLDocument xmlDocument = parseXMLDocument(xml);
XMLDocument schemaXMLDocument = parseXMLDocument(schema);
XMLSchema xmlSchema = (XMLSchema) new XSDBuilder().build(schemaXMLDocument, null);
xsdValidator.setError(xmlError);
xsdValidator.setSchema(xmlSchema);
xsdValidator.validate(xmlDocument);
return getValidationError(xsdValidator);
I get the following error:
Can't find resource for bundle oracle.xml.mesg.XMLResourceBundle, key XSD-2046.
I tried to validate this XML document using two other libraries - XSD Schema Validator (http://apps.gotdotnet.com/xmltools/xsdvalidator/Default.aspx) and xsdvalid-29 (http://www.w3.org/XML/Schema#XSDValid). Both libraries pointed me on the error that the type of root element is abstract and it cannot be used for doing validation.
I think that Oracle should return me explaining message but not to throw exception.
Am I right? Is there really Oracle bug or I miss something?
Any help, hits, advices would be gratfully apriciated.

Define Element1 as follows:
<xs:element name="Element1">
<xs:complexType>
<xs:complexContent>
<xs:restriction base="xs:string"/>
</xs:complexContent>
</xs:complexType>
</xs:element>
Does the XML document get validated if the element is specified as
<Element1></Element1>

How to validate xml document again schema

I need to create an xml document from sql retrieval. This xml document needs to be validated by xslt and xsd.
The problem that I am having is that with some criteria, that xml document passed the validation, while others do not.
Is there a way to check the xml document against the xsd to see which record does not pass the validation? Thanks.

Not able to validate the xml document against DTD using SAX

Hi ,
i am not able to validate xml document against its DTD using SAX parser even after setting setValidating = true. even if the file is not correct according to DTD , it is not throwing any exception. what could be the reason.? please help..
kranthi
this is the code sample i used.
SAXParserFactory factory = SAXParserFactory.newInstance();
factory.setValidating(true);
     try {
factory.newSAXParser().parse(new File("sample.xml"), handler);
     } catch (SAXException e) {
     e.printStackTrace();                         System.exit(2);

Hi karthik
Thanks for your response
Actually iam a beginner in java coding hence struggling to come up with the things
I tried putting your code and onserver side i see it is returning 09:12:17,234 INFO [STDOUT] [root: null]
actually the same program i wrote in java
and the same method i was calling from the main
and it is working fine and the xml document is getting displayed one important thing to be noted here is that the factory.newDocumentBuilder().parse(new File(filename));is returing XmlDocument
and the printing takes place
but the in same method public static Document parseXMLFile(String filename, boolean b) in servlet
the line factory.newDocumentBuilder().parse(new File(filename)); is returning DeferredDocumentImpl
and this creating problem , had it returned XmlDocument
i would have printed the elements one one
but as it is returning deferredimpl
iam unable to print the elements
could you please tell me why factory.newDocumentBuilder().parse(new File(filename)); is returning DeferredDocumentImpl
in servlets but in plain java pogram it is returing XmlDocument
Thanks

Problem validating XMl document

Hi everyone,
I'm facing a problem validating a XML document with Apache toolkit under windows XP and eclipse 3.0
I generate a pair of public/private keys using the RSA algorithm. The keys are of arbitrary length, but satisfying RSA conditions, ie we can encrypt and decrypt.
I can sign my XML document, but no way to validate it. Validation is only ok when I generate random keys using the KeyPairGenerator.
Do you think that arbitrary length keys don't allow to validate XML document. And do you have any idea how to solve the problem ( I'm not allowed to generate fixed length keys) ?
Thansk a lot for your precious help.

solved!
urghh...forgot to load th eschema..duh. (must be friday)
here's the fixed code:
    // parse the xml document (validate the xml string using a schema file)
    // the xml document does not specified the System ID or location of
    // schema..and use no namespace
    public void parse(HandlerType type, String xmldoc) throws SAXException, IOException {
        File           schema      = schemaMap.get(type);
        DefaultHandler handler     = handlerMap.get(yype);
        XMLReader   reader = XMLReaderFactory.createXMLReader(VENDOR);
        InputSource source = new InputSource(new StringReader(xmldoc));
        reader.setContentHandler(handler);
        reader.setFeature("http://xml.org/sax/features/validation", true);

Validate XML with Schema?

So, according to Adobe...
quote:
Dreamweaver CS3 continues to support not only the creation
and editing of XML and XSL files, but it also allows you to import
DTDs and schemas and to validate XML documents.
Does anyone know how to accomplish this task? Adobe's
documentation on this topic seems be less current than their
marketing material.
I mean, I'm assuming from the way this is worded it means
that you can "import DTDs and schemas and ... validate XML
documents"
with said schemas. Or is this just some shifty marketing
trickery which really means you can import (i.e., open) a DTD or
schema, and, as a completely unrelated task, you can "validate"
your XML file - to the extent that Dreamweaver will tell you if you
forgot to close a tag?

I tried to move all the xml, class and xsd files in the same folder and it still didn't work...
And I can't hard coded the xsd file on the document... so the only way is to set the xsd location inside the java codes... here's what I have:
static final String JAXP_SCHEMA_LANGUAGE = "http://java.sun.com/xml/jaxp/properties/schemaLanguage";
static final String W3C_XML_SCHEMA = "http://www.w3.org/2001/XMLSchema";
static final String JAXP_SCHEMA_SOURCE = "http://java.sun.com/xml/jaxp/properties/schemaSource";
File xsdFile = new File("schema.xsd");
saxParser.setProperty(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);
saxParser.setProperty(JAXP_SCHEMA_SOURCE, xsdFile);
Please help... thx.

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?

The method to set the DTD is setDoctype().

// Test using InputSource
parser = new DOMParser();
parser.setErrorStream(System.out);
parser.showWarnings(true);

inSource = new InputSource(r);
inSource.setSystemId(createURL(args[2]).toString());
parser.setDoctype(dtd);

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.

Sign XML document without KeyPairGenerator

Hi everyone -----> System.out.println("HEEEELP!");
I have a problem for signing and validating an XML document, using the Apache toolkit and JWSDP.
Example :
XMLSignature signature = fac.unmarshalXMLSignature(valContext);
boolean coreValidity = signature.validate(valContext);
When I genreate keys with KeyPairGenerator, everything works fine (The KeyPairGenerator uses crt coefficient). But If I use my own RSA keys (modulus, private and public exponent), I can sign but not validate the XML document, ie the signature value of the signedInfo. Strange thing : I'm sure the keys are correct. I can encyrpt and decrypt messages using my own validation program with these keys.
Does anyone know how to sign and validate XML documents with its own keys ?
I can reply more details if necessary ...
Any help would be very very appreciated :)

You're putting words in my mouth, I never mentioned DOM.
What I'm saying is that JAXB is not of concern to your requirements. Whatever happens to the objects after they are created from XML is up to you. It has done its job, the XML has been transformed into object set A. Perhaps at some point in time it can do some more work for you, when you have an object set B that need to be written to an XML structure. How you get from A to B, that's up to you.
But perhaps there is a more suited tool for the job that actually deals with XML transformations (hint hint). You could probably hack something together with basic SAX. Heck, if all you want to do is replace easy to identify lines of data with other lines of data a BufferedReader/BufferedWriter could already work.

How to validate generated XML-Document in Memory by XML-Schema?

Hi all!
I have the following problem:
I am generating a Document using the DOM delivered with Xerces 2.6.2.
Before I'll send the generated xml-document through network to another system I have to check with my xml-schema if the document is correct.
In the DOM-FAQ I found an "example" trying to explain how it should work. But with this example the problems begin.
I am creating my document with this method:
     public void createDocument() {
          myDOM = DOMImplementationImpl.getDOMImplementation();
          doc = myDOM.createDocument("", "documentData", null);
          root = doc.getDocumentElement();
          root.setAttribute(
               "xmlns:xsi",
               "http://www.w3.org/2001/XMLSchema-instance");
          //          root.setAttribute("xsi:noNamespaceSchemaLocation", "myScheme.xsd");
          domConfig = ((DocumentImpl) doc).getDomConfig();
          domConfig.setParameter(
               "schema-location",
               "file:///d:/workspace/XMLProject/WebContent/WEB-INF/myScheme.xsd");
          domConfig.setParameter("error-handler", new EHandler());
          domConfig.setParameter("validate", Boolean.TRUE);
     }In the line getting the domConfig, it is getting differeing to the example: The example is like this:
import org.w3c.dom.Document;
import org.w3c.dom.DOMConfiguration;
import org.w3c.dom.ls.LSParser;
Document document = builder.parseURI("data/personal-schema.xml");
DOMConfiguration config = document.getConfig();
config.setParameter("error-handler",new MyErrorHandler());
config.setParameter("validate", Boolean.TRUE);
document.normalizeDocument();They get the DOM-Configuration from the document-Object, but my document-Object has no "getConfig()" and only after type-casting I get a getDomConfig()-Method to get the configuration.
Then I fill my document and call
((DocumentImpl) doc).normalizeDocument();When I run my Application I get the following error:
org.w3c.dom.DOMException: FEATURE_NOT_SUPPORTED: The parameter schema-location is recognized but the requested value cannot be set.
     at org.apache.xerces.dom.DOMConfigurationImpl.setParameter(Unknown Source)
     at xmlProject.createDocument(Convert.java:63)
     at xmlProject.Convert.main(Convert.java:154)I tried several ways to get the validation without success.
The next question is how I should refer to my xml-schema (which path) and where to place it relative to my jar I will generate, because I will have no webserver I could place it on.
Has anyone any experience with validating a document created and not placed on disc?
I have also another question to SAX: I read, that it is reading a document without saving it in the memory. I think this means that if I am validating it by SAX it will be read once and for parsing it will be read a second time. If I would transfer the document over an tcp-connection, I only have the document once in my inputstream and after validation it would be consumed I think. But what can I parse then? Or did I missed a detail with the function of the SAX?
Thank you for your help!
Yours

9.0.3 validates an invalid XML document as valid

JDeveloper 9.0.3 validates the XML document below with no errors, although it contains several. It also insists on a namespare (even a blank one) before the validator will run, even though it has an internal DTD.
Also, there is no DTD file type in JDeveloper. Why?
-----------------------Clip here-----------
<?xml version="1.0"?>
<!DOCTYPE todo [
<!ATTLIST description priority NMTOKEN "low">
<!ELEMENT description (#PCDATA)>
<!ELEMENT task (description)>
<!ELEMENT todo (task)+>
]>
<todo xmlns="">
<task>
<description priority="high">Backup sales data for last month</description>
</task>
<task>
<description priority="l ow">Complete end of month report</description>
</task>
<task>xxx</task>
</todo>

Ed,
JDev 9.0.3 supports validation based on XML Schema only, not DTD.
DTD validation is being considered for a future release, but has not
been scheduled yet so I cannot give you an idea of when it's coming.
I'll try to encourage the team to write a little Extension we could
put up on OTN to restore this validate against the DTD feature that
JDeveloper 3.2 did support.

Validate and update a XML document with rules

Hi,
In my project work, I am thinking about using oracle rules BRMS (business rule management system) to validate certain rules on xml document.
Since I am new to the oracle rules, I want to know the feasibility of doing this with oracle rules.
I have a specific question...
I have XML documents that are in different schema versions. these schema are fixed but can add them in future as well.
I have two things to do:
1. transform a given XML document (in a one version) to another version
2. Validate the new XML document against the rules defined in the oracle business rules.
1.I can do the 1st task using XSLT transformation. But there is one challenge. Assume that there are new tags are added in the target schema compared to the source schema of the XML document.
If there are optional tags to be added, I want to know if oracle rules can be used for that. Because I want to make these things done without changing the code (java) or the application internals.
2. I have few questions on the 2nd issue. They are:
a) can I create rules in oracle BRMS based on target schemas. (or to all of them. If so, what needs to be done if I add a new schema in future. How to update the rules?)
b) is it possible to group the rules created above in oracle BRMS.
Lets say
R1, R2 rules are created against schema1 (version 1)
R3, R4, R5 rules are created against schema2 (version 2)
R6, R7 rules are created against schema3(version 3)
Can I create group R1, R2 and R6 rules in to a one group (G1) and R1, R2 and R7 rules in to another group (G2).
What are the APIs available in oracle BRMS to retrieve above defined groups at run time? (because business user can define any rules, ad group them at run time)
Once I have the groups, How can I validate a XML document against a group created above? What are the APIs available for this.
c) is it possible to add/update/delete tags to a XML document based on rules in oracle BRMS? if so, how?
appreciate your valuable feedback on this..

Hi Hareendra,
I think you should post your question in this other forum:
