Mapping XML documents in Oracle

I am a newbie in Oracle.
I would like to know how to store entire XML documents in CLOBS.
Since yesterday I hear about XSQL, and I was wondering if nobody had some sample code to realize this mapping.
Thanks in advance for your help

Hi,
You're missing the namespace prefix on some elements.
This should work :
SQL> SELECT flux_name, elment_1, elment_2, elment_3

Very urgent help needed- Error while passing XML document to Oracle stored

Hi !
I have been struggling a lot to call Oracle 9i stored procedure passing Stringbuilder object type from ASP.NET
I am using Visual Studio 2008 Professional, OS: Windows XP and Oracle: 9.2.0.1.0
Following is the procedure:
CREATE or REPLACE PROCEDURE loadCompanyInfo (clobxml IN clob) IS
-- Declare a CLOB variable
ciXML clob;
BEGIN
-- Store the Purchase Order XML in the CLOB variable
ciXML := clobxml;
-- Insert the Purchase Order XML into an XMLType column
INSERT INTO companyinfotbl (companyinfo) VALUES (XMLTYPE(ciXML));
commit;
--Handle the exceptions
EXCEPTION
WHEN OTHERS THEN
raise_application_error(-20101, 'Exception occurred in loadCompanyInfo procedure :'||SQLERRM);
END loadCompanyInfo ;
And following is the ASP.net code:
StringBuilder b = new StringBuilder();
b.Append("<?xml version=\"1.0\" encoding=\"utf-8\" ?>");
b.Append("<item>");
b.Append("<price>500</price>");
b.Append("<description>some item</description>");
b.Append("<quantity>5</quantity>");
b.Append("</item>");
//Here you'll have the Xml as a string
string myXmlString1 = b.ToString();
//string result;
using (OracleConnection objConn = new OracleConnection("Data Source=testdb; User ID=testuser; Password=pwd1"))
OracleCommand objCmd = new OracleCommand();
objCmd.Connection = objConn;
objCmd.CommandText = "loadCompanyInfo";
objCmd.CommandType = CommandType.StoredProcedure;
//OracleParameter pmyXmlString1 = new OracleParameter("pmyXmlString1", new OracleString(myXmlString1));
objCmd.Parameters.Add("myXmlString1", OracleType.clob);
objCmd.Parameters.Add(myXmlString1).Direction = ParameterDirection.Input;
//objCmd.Parameters.Add("result", OracleType.VarChar).Direction = ParameterDirection.Output;
try
objConn.Open();
objCmd.ExecuteNonQuery();
catch (Exception ex)
Label1.Text = "Exception: {0}" + ex.ToString();
objConn.Close();
When I am trying to execute it, I am getting the following error:
Exception: {0}System.Data.OracleClient.OracleException: ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'LOADCOMPANYINFO' ORA-06550: line 1, column 7: PL/SQL: Statement ignored at System.Data.OracleClient.OracleConnection.CheckError(OciErrorHandle errorHandle, Int32 rc) at System.Data.OracleClient.OracleCommand.Execute(OciStatementHandle statementHandle, CommandBehavior behavior, Boolean needRowid, OciRowidDescriptor& rowidDescriptor, ArrayList& resultParameterOrdinals) at System.Data.OracleClient.OracleCommand.ExecuteNonQueryInternal(Boolean needRowid, OciRowidDescriptor& rowidDescriptor) at System.Data.OracleClient.OracleCommand.ExecuteNonQuery() at Default.Button1Click(Object sender, EventArgs e)
I understand from this that the .net type is not the correct one, but I am not sure how to correct it. I could not find any proper example in any documentation that I came across. Most of the examples give information on how to read but not how to insert XML into Oracle table by calling Stored Procedure.
Can you please help me to solve this problem? I hope that you can help solve this.
Also, can you please give me an example of passing XML document XMLdocument to Oracle Stored procedure.
In both the cases, if you can provide the working code then it would be of great help.
Thanks,

Need help in Parsing XML Document in Oracle

Hello Experts,
I urgently need your help. We have xml document on the Web but not on the File System. How can I parse the xml document on the web in Oracle.
Any link, blog or sample code would be appreciated.
Your help would be appreciated.
Kind Regards,
Bhavin

This breaks down to two issues
1) Getting the XML into Oracle
2) Parsing the XML inside Oracle
For #1, the first two options that come to my mind are httpuirtype and utl_http. Both can be used to get information from a URL that understands HTTP requests.
For #2, you can treat the XML as a DOMDocument or XMLType to parse it. You also could parse it via a SQL statement using XQuery or XMLTable as well.
Many of those examples can be found on the {forum:id=34} forum or [Marco's blog|http://www.liberidu.com/blog/]. A few parsing examples that I've done can be seen at {message:id=3610259}, make sure to also follow the link I put in there to a previous example before that.

How can i use a xsd while generating my xml document in oracle?

Hi, how can i use a xsd while building my xml document query, so i know the xml was built properly?
Cheers.

Hi,
Do you want to validate your xml against xsd?
Read this

There are some bugs also, for example xml is invalid but no errors when calling schemaValidate()

Use JDBC to Access XML Documents in Oracle XML DB

Hi folks,
From the Oracle XML DB Developer's Guide 10g Release 1 (10.1) Chapter 12 Java API for XMLType, it show several examples for how java application use JDBC to access xml in XMLDB:
1. use getOPAQUE() on XMLTYPE table/column and then call XMLTYPE.createXML();
2. use getCLOBVal()/getStringVal()/getBLOBVal() in SQL statement;
3.use getObject on the result and cast directly to XMLType;
Among these 3 options, which is supposed to be the fastest way? Any difference between thin and oci?
I have run some tests about that and the result is the second option (with thin driver) is the fastest. It surprises me because I think oci should be faster than thin. Does the result make sense?
Thanks.

Have you tried to trace your sessions to see how much work is happening? Traces should give you quantifiable information on exact times and access paths to the data.
Below is a link to an O'Reilly book excerpt on Java programming with JDBC. Slightly data, but may be of assistance.

Castor XSD Code Generation ANT task: mapping XML file?

Hello,
I am new to Castor and am using the Castor Code Generator ANT task to generate code from a XSD schema file.
I am using a binding XML file as well. One thing that I have a question about is the needed XML mapping file. I set the ‘*generateMapping*’ attribute to ‘true’ but have not found a mapping XML document.
Is there something I am doing wrong?
I would have attached the XSD files(some are imported), binding XML file and the ANT build.xml file in a .zip file to this post, but this forum does not have a facility for file attachments, but I can email them upon request.
Thanks in advance,
Andrew

Hi Andrew,
JAXB is the Java standard (JSR-222) for generating Java classes from an XML schema. Several implementations of this standard are available:
- Metro JAXB: The JAXB reference implementation, available in Java SE 6 and as part of GlassFish
- EclipseLink JAXB (MOXy): Part of EclipseLink, also available in Oracle TopLink
- JaxMe: Available from Apache
- Etc...
Castor is a proprietary XML binding tool. For Castor related questions you should visit the Castor website.

XML Document Generation

Dear All
I have a requirement to generate xml document from database as per given XML schema definition. I did this by using oracle report developer to generate out put as xml document.
My question is that is there any sequence important for attribute for example
XSD has attribute
Name
Address
phoneno
But When i generate xml document using oracle report developer it changes the sequence of attributes like this
phoneno
address
name
please guide that this wrong sequence of attribute have any problem when validating xml document with xsd.
Regards

XML 1.0 specifications :
http://www.w3.org/TR/REC-xml/#sec-starttags
The Name in the start- and end-tags gives the element's type. [Definition: The Name-AttValue pairs are referred to as the attribute specifications of the element], [Definition: with the Name in each pair referred to as the attribute name ] and [Definition: the content of the AttValue (the text between the ' or " delimiters) as the attribute value.] Note that the order of attribute specifications in a start-tag or empty-element tag is not significant.

Issue with mapping XML to Java using SAX API

I am using SAX API to Map XML Documents To Java. Is it possible to differentiate the elements based on the attribute rather than localname or element name in SAX API? because I am having the below xml structure. In SAX API we are processing the element values based on start/End Element name.

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>

Sample xml document:
<?xml version="1.0" encoding="UTF-8"?>
<RObject xmlns="http://www.x.com/test"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://localhost:8080:/test.xsd">
<theID xmlns="">123</theID>
<title xmlns="">title</title>
<theName xmlns="">name</theName>
</RObject>
Register Schema call:
BEGIN
DBMS_XMLSCHEMA.registerSchema(
SCHEMAURL => 'http://localhost:8080/test.xsd',
SCHEMADOC => bfilename('TMP3','test.xsd'),
LOCAL => TRUE,
GENTYPES => TRUE,
GENTABLES => TRUE,
CSID => nls_charset_id('AL32UTF8'));
END;
Insert xml document call:
insert into "RObject566_TAB" values
(XMLType(bfilename('TMP3','test.xml'),nls_charset_id('AL32UTF8')));
Changing NextObjectType to this gets insert to work:
<xs:complexType name="NextObjectType" abstract="true">
<xs:sequence>
<xs:element name="theID" type="xs:string"/>
<xs:element name="title" type="xs:string"/>
</xs:sequence>
</xs:complexType>

BTW: This is with Oracle 10.2.0

Error serializing XML document.

We are trying to serialize XML document using Oracle XML Parser (9.2.0.5.0).
Here is the code used for serialization
public static void write(Document doc, File resultFile) {
try {
// Create a TransformerFactory
TransformerFactory transformerFactory = TransformerFactory.newInstance();
// Create a new Transformer for Identity Transformation
Transformer transformer = transformerFactory.newTransformer();
// Make passed document the DOM source
DOMSource source = new DOMSource(doc);
// Make result file the Stream Result
StreamResult result = new StreamResult(new FileOutputStream(resultFile));
// Write the document by means of Identity Transformation
transformer.transform(source, result);
} catch (Exception exc) {
exc.printStackTrace();
Document to be serialized
test.xml
<?xml version="1.0"?>
<!DOCTYPE test SYSTEM "test.dtd">

<Test>
<TestElement>Test Data</TestElement>
</Test>
test.dtd

<!ELEMENT Test (TestElement)>
<!ELEMENT TestElement (#PCDATA)>
The serialized document looked like
<?xml version = '1.0'?>
<?#comment This is a comment ?><Test>
<TestElement>Test Data</TestElement>
</Test>
First of all the DOCTYPE declaration was not present in the serialized document.
Secondly the comments appeared in a wrong way, which even made it an invalid XML document.
How do we get this to work?
Thanks

On 9.2.0.3.0 you can try dbms_xdb.deleteResource(Path,4)
