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.

Getting an Out of memory exception while validating XML against XSD

Hello friends,
I am getting an Out Of Memory exception while validating my XML against a given XSd which is huge.
SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();
        saxParserFactory.setValidating(true);
          SAXParser saxParser = saxParserFactory.newSAXParser();
         saxParser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaLanguage", "http://www.w3.org/2001/XMLSchema");
         saxParser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaSource",new File("C:/todelxsd.xsd")); as u may see the darkened code. this basically Loads the XSD in Memmory , and JVM throws an out of Memory exception. is there any other way round of validating an XML against an XSD where i dont have to load my XSD if not then kindly let me know the solution for above problem .
Thanks.

Yes, but increasing the heap size is a temporary solution , isnt there a way where the XML can be validated against an XSD without having to load XSD in memory

When validating XML against XSD DateTime not getting recognised

In the XSD the element is defined as
<xs:element name="CreateDate" type="xs:dateTime" nillable="true" minOccurs="0"/>
<xs:element name="CreateUser" type="xs:string" nillable="true" minOccurs="0"/>
<xs:element name="ModifyDate" type="xs:dateTime" nillable="true" minOccurs="0"/>
in the XML
<CreateDate>1995-04-19 14:37:43</CreateDate>
<CreateUser>JDC</CreateUser>
<ModifyDate>2010-09-21 14:37:43</ModifyDate>
When i validate it
its throwing me error.
ORA-30992 error occured at xpath
ORA-01861 leteral does not match format string.
But when i remove the Time part then it is not throwing error.
<CreateDate>1995-04-19</CreateDate>
<CreateUser>JDC</CreateUser>
<ModifyDate>2010-09-21</ModifyDate>
Help me out.

Your date/time value is formatted incorrectly.
See http://www.w3.org/TR/xmlschema-2/#dateTime
The ·lexical space· of dateTime consists of finite-length sequences of characters of the form: '-'? yyyy '-' mm '-' dd 'T' hh ':' mm ':' ss ('.' s+)? (zzzzzz)?, whereSo you are missing the T between the date and time.
I will agree that the error message is not too helpful. How are you validating it and what version of Oracle (4 digits)?

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..
but unfortunately, only the xsd file can be set locally and still there needs the internet connection for the other features, properties.

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

--> Could not find cached enumeration value Custom.CI.Enum.PeripheralDevice.Printer for property Type, class BMC.Custom.CI.PeripheralDevice in enumeration cache.
You must specify either the Name or Guid of an enumeration of type Custom.CI.Enum.PeripheralDevice.Type.
Be sure that you are specifying the Name property of the enumeration value you want to set, and not the DisplayName; the Internal Name is something like "IncidentCategoryEnum.Category" for out of the box enumerations, or ENUM.210ADA2282FDABC3210ADA2282FDABC
for enumerations created in the console.
you can check this by finding the enumeration in the XML or by using the the
SMLets commandlet
Get-SCSMEnumeration | ?{$_.DisplayName –eq “Printer”}
and then checking your value with
Get-SCSMEnumeration -Name "ENUM.210ADA2282FDABC3210ADA2282FDABC"
and see if you get the right displayname back

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.

Validate XML against XSD with imported xsd's

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 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.

Does XDB supports validating xml against multiple schemas?

The XMLType has some methods for validating an xml documents against a schema, e.g., SCHEMAVALIDATE, etc.. does XDB support validating xml against multiple schemas (Just like what JAXP or Xerces have done)? Or what's the current situation about this issue? thanks.

did you try using the import schema element instead of the include elemnt?

Validating XML against an XML Schema using PL/SQL

Hello everyone,
I've a strange problem.
I'm trying to validate an XMLTYPE variable against an XSD schema using the XMLisValid function.
The XML I was trying to validate was returning false (0) when using this method.
However, when I register the XSD against a column in a table and then insert this XMLTYPE into that column, I do not get any errors. If I change the XSD to ensure failure when using this method, I do get an error, so it is registered and working.
I have then created a very basic XSD and both methods work when validating the XML against this. So obviously the more complicated XSD I want to validate against is making a difference, but I would expect them to either both fail or both pass, not one fail and one pass.
Does anyone know why they'd be returning different results?
Thanks in advance for your help.

Steps to validate XML data against a schema in Oracle:
1. Register your XSD in the database.
begin
dbms_xmlschema.registerschema(
SchemaUrl,
SchemaDoc,
local => TRUE/FALSE);
end;
2. For validating your XML document against your registered schema, here is a sample pl/sql block.
declare
v_xml xmltype;
begin
v_xml := your_xml_document;
v_xml.schemaValidate();
end;
Hope this helps :)

Validate XML against XSD

Hi. I need to validate an XML file against XSD schema.
How can I do it with PL/SQL?
Thanks a lot
Alejandro

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
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

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.

Hi, I'm not an expert but I've been reading a lot and I found this and it works. I'll hope it is useful.(Oracle 10)
declare
-- Local variables here
res BOOLEAN;
tempXML XMLType;
xmlDoc XMLType;
xmlSchema XMLType;
schemaURL varchar2(256) := 'testcase.xsd';
schemaPath varchar2(256) := '/public/testcase.xsd';
begin
dbms_xmlSchema.deleteSchema(schemaURL,4);
-- Test statements here
xmlSchema := xmlType(
'<?xml version="1.0" encoding="UTF-8"?>

Question about validating xml against schema

Hi,
I am new to JAXP. I try to validating a xml against a schema. I wrote following code:
SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setNamespace(true);
spf.setValidating(true);
SAXParser sp = spf.newSAXParser();
sp.setProperty("http://java.sun.com/xml/properties/jaxp/schemaLanguage",
"http://www.w3.org/2001/XMLSchema");
sp.setProperty("http://java.sun.com/xml/properties/jaxp/schemaSource",
"mySchema.xsd") ;
sp.parse(<XML Document>, <ContentHandler);
but when compile, it has error: can't resolve ""http://java.sun.com/xml/properties/jaxp/schemaLanguage", and
"http://java.sun.com/xml/properties/jaxp/schemaSource".
It seems it didn't support above two property.
I saw some code in forum is:
fact.setFeature("http://xml.org/sax/features/validation", true);
fact.setFeature("http://apache.org/xml/features/validation/schema",true);
fact.setFeature("http://apache.org/xml/features/validation/schema-full-checking", true);
SAXParser sp = fact.newSAXParser();
sp.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",schemas);
Why sun tutorial use property:http://java.sun.com/xml/properties/jaxp/schemaLanguage
and someone use:http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation
where to get information about setting properties for SAXParserFactory?
Thanks

In the past, ColdFusion's XML validation mechanism seems to have had issues with schemas that contain imports, e.g., http://forums.adobe.com/message/155906. Have these issues still not been resolved?
Do you not think that perhaps you're answering your own question here?
I don't see an issue about this on the bug tracker. It might be an idea if you can get a simple, stand-alone repro case together and raise an issue (and post the reference back here and against that other thread so people know to vote for it). If you post the repro case here too, it would be helpful.

Not giving full because it's too long.
1. I Successfully registered Schema into database
2. Then i generate table from registered Schema
2. In my java code i validated XML document against Schema and it's successfully validate.
3. But when i stored this XML into this generated table it's give me error
Like :
INSERT INTO XMLTABLE
VALUES
(XMLTYPE(bfilename('MYDIR','testabc.xml'),NLS_CHARSET_ID('AL32UTF8')))
Error report:
SQL Error: ORA-31061: XDB error: XML event error
ORA-19202: Error occurred in XML processing
LSX-00333: literal "94032000" is not valid with respect to the pattern
And i have to store this xml into this tables so what i have to do ?

Thanks for your reply odie_63.
I got this my error solution. My XML document is not well structured based on my registered XML Schema.
Means In My XML Document there are some invalid value and that not match my schema pattern so it's gives this error
SQL Error: ORA-31061: XDB error: XML event error
ORA-19202: Error occurred in XML processing
LSX-00333: literal "94032000" is not valid with respect to the pattern
For Solution we have two ways
1. I have changed this literal "94032000" value in my xml file then save it.
2.
- We have to delete this schema then
- we have to change Schema pattern for particular element
like :--
<xs:restriction base="xs:string">
<xs:whiteSpace value="preserve"/>
<xs:pattern value="[0-9]{3}"/>
</xs:restriction>
- then store xml into database it works..
Thanks.
