Error while Validating xml against a schema using jaxp

Hi All,
Following code validates xml against a schema using JAXP .It gives SAXNotRecognizedException error when you run the program.
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";
SAXParserFactory myFactory = SAXParserFactory.newInstance();
myFactory.setNamespaceAware(true);
myFactory.setValidating(true);
javax.xml.parsers.SAXParser parser;
String filename = "C:/Note.xml";
File xmlFile = new File(filename);
try
     DefaultHandler handler = new DefaultHandler();
     parser = myFactory.newSAXParser();
     parser.setProperty(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);
     parser.parse(xmlFile, handler);
catch (ParserConfigurationException e)
     // TODO Auto-generated catch block
     e.printStackTrace();
catch (SAXException e)
     // TODO Auto-generated catch block
     e.printStackTrace();
catch (IOException e)
     // TODO Auto-generated catch block
     e.printStackTrace();

How do i fix the above mentioned problem ?
Thanks in Advance.

Validate with the JAXP DOMParser instead of the JAXP SAXParser.
To validate with a SAXParser use the xerces SAXParser.

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.
Robin

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 :)

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.
I got connect with service, got the response and so I went to validate that xml with an xsd file.
But I got an error on that task. The error occurs in the following line

          } catch (ParserConfigurationException e) {

I need to extract the values from all of the columns : sheet_number, appl_number1, rating1, criteria1, appl_number2, rating2, criteria2. Validate the data and insert into oracle tables.
I'm having dificulties extrating the data from the "z:row" recordset
Can anyone help with the syntax ?
I'm use to extracting with tags using syntax like this
declare
v_xml_content XMLTYPE;
begin
v_xml_content := db_get_xml_from_file (p_file_name, p_directory, 'ISO-8859-1');
FOR f IN (SELECT value(x) file_data
FROM TABLE
(xmlsequence
(extract (v_xml_content,'/data'))) x) LOOP
SELECT extractvalue(f.file_data,'/data/row') into v_row from dual;                                                                      END LOOP;

Building XPath with the XML having the Namespace using PL SQL

While trying to build the path of each node, when the XML has no namespace in it , the below code works fine providing the result
1~/
2~/person/
3~/person/age/
4~/person/homecity/
5~/person/name/
6~/person/homecity/lat/
7~/person/homecity/name/
8~/person/homecity/long/
But when the xml is changed to
<person xmlns="urn:person" xmlns:lat="urn:lat">
<name>Rob</name>
<age>37</age>
<homecity>
    <name>London</name>
    <lat>123.000</lat>
    <long>0.00</long>
</homecity>
</person>"
The result on executing the below code is resulting into only into below result
1~/
2~/person/
In the XML provided above, XML name space is not constant and it may vary for every XML. My requirement is to parse the complete XML, where i can read the XML with namespace and get the result as mentioned below
1~/
2~/person/
3~/person/age/
4~/person/homecity/
5~/person/name/
6~/person/homecity/lat:lat/
7~/person/homecity/name/
8~/person/homecity/long/

Hi,
Thanks for the reply.
Please find the details :
1) What's your database version ?
Database version :
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
2) What's the practical use of extracting all the paths like this, what are you trying to achieve, besides a purely academic exercise ?
The XML provided was for sample XML.
The practical use being ,I wanted to parse the SEPA messages using the below code snippet dynamically.
create table data_table (
     data xmltype
    xmltype column data store as securefile binary xml
insert into data_table values (
    xmltype('<?xml version="1.0" encoding="UTF-8"?>

The idea was to :
1). Map the Column Names for the XPath built using the previous code.
2). Build the Select statement shown above dynamically based on the Xpath built in the previous code using a PLSQL block, and to process the data by doing a bulk collect on the XML.
The above XML may contain multiple <FIToFICstmrCdtTrf></FIToFICstmrCdtTrf> nodes.
Since the name space in the XML varies for each version of the SEPA messages , i need to get the names spaces ALSO to be picked up dynamically and parse the XML data based on the select statement as shown above.
Could you please guide me with
1). Is the approach taken appropriate?
2). Any alternative approach should be looked for ?
3). How to extract the name spaces available in the XML?
Thanks.

Validating xml with external schema

Hi,
I want to validate a xml against an external schema using java and the xml WILL NOT contain any reference to the schema. Any help in the matter is most welcome.
A typical example of such an xml is given below:
<Envelope >
<Body>
" Some content here"
</Body>
</Envelope>
I used the following code but it did not validate the xml.It simply parsed.
public class TestParser {
     public static void main(String[] args) {
          final String JAXP_SCHEMA_LANGUAGE = "http://java.sun.com/xml/jaxp/properties/schemaLanguage";
          final String JAXP_SCHEMA_SOURCE = "http://java.sun.com/xml/jaxp/properties/schemaSource";
          try {
               SAXParserFactory saxpfactory = SAXParserFactory.newInstance();
               saxpfactory.setNamespaceAware(true);//
               saxpfactory.setValidating(true);//
               SAXParser parser = saxpfactory.newSAXParser();
               parser.setProperty(JAXP_SCHEMA_LANGUAGE, "http://www.w3.org/2001/XMLSchema");//
               parser.setProperty(JAXP_SCHEMA_SOURCE, "http://www.w3.org/2001/06/soap-envelope");//
               parser.parse(new File("C:\\TEMP\\request.xml"), new DefaultHandler());
          } catch (FileNotFoundException fileNotFoundException) {
               fileNotFoundException.printStackTrace();
          } catch (IOException ioException) {
               ioException.printStackTrace();
          } catch (SAXException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          } catch (ParserConfigurationException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          System.out.println("exiting main ");

How to validate an xml with a schema w/o specifying the schema in the xml

I have done xml validation with xml schemas, where the xml points to the xsd to use. However, I would like to not have to specifiy the xml schema in the xml document (and can't ensure that the xml coming to us has that in it). How do I, in the java code, tell it what schema to use in validation?
Brian

static final String schemaSource = argv[0];
static final String JAXP_SCHEMA_SOURCE =
"http://java.sun.com/xml/jaxp/properties/schemaSource";
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
factory.setAttribute(JAXP_SCHEMA_SOURCE,
new File(schemaSource));

Validate xml with complextype schema without root element!

Hi All!
I have a problem that. I want to validate a xml data of complextype but the schema i want to validate is[b] not have root element.
For example:
The schema like that
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema targetNamespace="www.thachpn.test" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="www.thachpn.test" elementFormDefault="qualified" attributeFormDefault="unqualified">
     <xs:complexType name="Name">
          <xs:sequence>
               <xs:element name="FirstName" type="xs:string"/>
               <xs:element name="LastName" type="xs:string"/>
          </xs:sequence>
     </xs:complexType>
</xs:schema>
and the xml data i want to validate like this
<?xml version="1.0" encoding="UTF-8"?>
<Name xmlns="www.thachpn.test" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
     <FirstName>Pham</FirstName>
     <LastName>Thach</LastName>
</Name>
My Algorithm is like that:
I create a complextype object by above schema
then i create new element with given name and namespace
after that i use schema of this element to validate xml data.
I use xmlparserv2 lib of oracle
But i can not find how to create complextype from schema or create element with have complextype.
Please help me.
Thanks a lot!

<?xml version="1.0" encoding="UTF-8"?>
Modify the schema.
Add a root element.
<xs:schema targetNamespace="www.thachpn.test" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="www.thachpn.test" elementFormDefault="qualified" attributeFormDefault="unqualified">
<xsd:element name="Name" type="Name"/>
<xs:complexType name="Name">
<xs:sequence>
<xs:element name="FirstName" type="xs:string"/>
<xs:element name="LastName" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:schema>

Getting the schema using Oracle SQL Developer 1.5.1

I need to generate a report in CSV/XLS format using Oracle SQL Developer 1.5.1 to get the schema details
in the below format.
Table Name: XXXXXXXXX
Table Space Name: XXXXXXXXXXXXXXX
Structure :
Field Name Data Type Size
Xxxxxxxx xxxxxx xxxxx
Xxxxxxxx xxxxxx xxxxx
Xxxxxxxx xxxxxx xxxxx
Xxxxxxxx xxxxxx xxxxx
Field level constraint:
Xxxxxxxxxxxxxxxxxx
Table Level Constraint:
Xxxxxxxxxxxxxxxxxx
Indexes:
Index Name Column Name(s) Table space name
Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
Sequence Number:
Xxxxxxxxxxxxxxxx
Triggers:
Xxxxxxxxxxxxxxxxxx
I am using a query to do that, but I cannot run more than one queries in the Create Report Dialog.
I went to the Menu->View->Reports. In that, I chose User Defined Reports, created a new folder called Schema Detail and in that a report named Schema Detail. I right click on that report, choose Edit option, Create Report Dialog opens.
In the Create Report Dialog, I chose the option Script for Value of Style.
In the SQL column I enter a query "select * from table_names". But, if I enter another query after that, it does not run and reports an error "SQL Error: ORA-00933: SQL command not properly ended
00933. 00000 - SQL command not properly ended" Cause: Action: "
I end the first query with a semi colon, but it does not work.
The queries run fine in a SQL Worksheet. There, I can terminate the first query with a semi colon and enter the second query. Then, I run both of them together so that result-set of second query appears after the second.
Am I doing something wrong? Can someone please advise on how to get the information I need?
Thanks a lot.

You can do it in SQL Worksheet because you are running a script. You could run the script in SQL*Plus, and even start it from a bat/cmd file.
Or if you want this as a User Defined Report, you might make it a PL/SQL style report. Here, all output is done through DBMS_OUTPUT.PUT or DBMS_OUTPUT.PUT_LINE. You can output HTML tags or plain text. I have an example in my paper for ODTUG Kaleidoscope 2009.

Convert ResultSet - Xml with Xml Schema in java

Hi
I am using Web Services created in java and will be used from .Net client. Since its a cross platform, so I need to convert the Java ResultSet to XML stream (with schema) so that it could be accesed by .NET client. So I want to know how to convet a Java ResultSet into the desired xml stream (with schema).I know .NET provides this facility through some methods of DATASET.
Will anybody tell me of any utility, tools or the methods so that I can accomplish this task.
Thank in advance

I would think that the easiest way to do this would be to use web-services. Get the JWSDP. I don't think there is a direct way to go from ResultSet to XML. You'd have to write or find an external tool, though Oracle can create XML straight from the database.

JAXB has been available as an early release download for some time. There are also XML Binding packages available from Borland (JBuilder) and Castor. These tools create Java classes from a source document, xml,dtd etc. You can use these classes to marshal-unmarshal XML documents.

Extract XML output to file using PL/SQL

Hi.
Since Oracle 8.1.4.7.1 I am using XML output in my applications.
With that version of Oracle, my method was:
1. Make the select;
2. Create a file somewhere in my C drive;
3. Create the XML file header;
3. For each row, insert into the file, with the correct format;
4. Close the file;
... and, voilá ... the XML file was made.
Now, with the Oracle 10g, I know that I have much more ways to do it:
1. Package DBMS_XMLQUERY
2. Statements like
"SELECT XMLELEMENT("USERS", XMLELEMENT("nome_pessoa", e.nome_pessoa ||' - '|| e.login), XMLELEMENT ( "password", e.password)) AS "result"
FROM pessoa e"
3. Or finally using XML SQL Utility.
My question, is that if there is any way that i can make it all of this automatically. If there is any procedure or method that allow me to do all this stuff in just one step:
1. Select in XML output;
2. Creation of file;
3. Insertion of Select output in file and Close of File;
Thankx,

I'm assuming that you want to write to the file system of the server that the database is running on...
you'll have to use utl_file
