How to generate XML from EBusiness suite ARXSGPO

Could someone tell me how I can generate XML from the EBusiness Suite Accounts Receivable report ARXSGPO.rdf I understand this report is called by a C program. I have tried changing the concurrent request to output format to XML the result does not resemble XML. Does anyone have any suggestions how I can generate XML from the ARXSGPO report?
Thanks,
Mark

Hi Mark
the next release of XMLP will have last page only support. The problem is that at the template layer you do not know how many lines are going to fit on the page, so you never know what is going to be the last page. The only way around it for now is to specify the number of lines to a page and then check when all the lines have been rendered and then render the remit portion.
I have a sample invoice that does the same, drop me a mail, you can work out the email from my name and the fact I work for XMLP Im sure.

Generate xml from xsd file

i would like to make my java application automaticaly convert a given .xsd file to an .xml one.
i know that with jdev you can generate an xml file from xsd one, and i want my application do the same thing.
i know also that i can use JAXB: first i bind the xsd file then i marshall the java class created to obtain xml. But i dont know how to do it.
is there a simple way to use the "things" behind the jdev xml generation from xsd.

Please refer
http://www.developer.com/java/web/article.php/3722211/Using-JAXB-in-JDeveloper-1013.htm
JDeveloepr 11g includes JAXB 2.0.

Generating XML from XSD

Hi,
I'm not sure it's possible to do what I want, but can anyone confirm / deny this:
I have a series of XSDs that I can load into the database. I want to be able to generate XML that conforms to the XSD, by passing in a series of variables - the values that I want to substitute in the XML are not held in the database, but are all calculated in PL/SQL.
A snippet from the XML is:
<Name>
<PersonDescriptives:PersonNameTitle/>
<PersonDescriptives:PersonGivenName/>
<PersonDescriptives:PersonFamilyName/>
</Name>I want to be able to pass in variables to supply the values in the XML, and generate it from the XSD. Is this possible?
My gut feeling (and initial quick analysis) says that it's not - the option I've come up with so far is simple string manipulation and then I could validate the XML against the XSD to ensure that it's valid, but then I have the issue of what to do if it isn't valid!
Any thoughts gratefully received,
Matt
Edited by: Darryl Burke -- advertisement and links removed

Thanks Mark.
I've look at the examples etc already, but they all seem to only cater for selecting from a database table. Since all my values are in PL/SQL variables rather than being in tables, I guess I could select from DUAL the whole time, but the performance of having to do it that way rather than just concatenating text together doesn't seem to make it worthwhile.
Think I'll just stick with using string manipulation to create the XML.

How to generate XML from relational data : PL/SQL or Java

I'm new to Oracle XML and would appreciate some advice. I've been asked to generate XML documents from data stored in relational tables. The XML documents must be validated against a DTD. We will probably want to store the XML in the database.
I've seen a PL/SQL based approach as follows :
1.Mimic the structure of the DTD using SQL object types 2.Assign the relational data to the object type using PL/SQL as required
3.Use the SYS_XMLGEN package to render the required XML documents from the SQL objects
However, creating the object types seems to be quite time consuming (step 1 above) for anything other than the simplest of XML documents.
I've also seen that there is the Java based approach, namely :
1. Use the XML generator to build Java classes based on a DTD.
2. Use these classes to build the required XML
On the face of it, the Java based approach seems simpler. However, I'm not that familiar with Java.
Which is the best way to proceed ? Is the PL/SQL based approach worth pursuing or should I bite the bullet and brush up my Java ?
Is it possible to use a combination of PL/SQL and Java to populate the dtd generated java classes (step 2 of the Java approach) to reduce my learning curve ?
Thanks in advance

To help answer your questions:
1) Now, in 9iR2, you can use SQL/XML as another choice.
2) You can also use XSU to generate the XML and use XSLT to transform it to a desired format instead of using object views if possible.
3) XDK provide Class generator support to populate XML data to Java classes.

Programmatically generating XML from XSD

Hello, everyone:
I saw the JDev10.1.3 demo for registering an XSD and then
saw how to manually create an XML instance in JDev.
Is there a mechanism (e.g., a command line utility) for
generating an entire XML instance that is conformant to
a registered XSD? If so, it would be nice to have the
ability to create multiple conformant XML documents,
but that might be too much to ask for right now:)
Regards,
Oswald
ps: I have an XSD that imports another XSD and it seems
that I was able to register this succesfully in JDev10.1.3,
whereas it did not work when registering
the XSD in an Oracle 10G instance via 'registerSchema'.

Hello:
Thanks for the update, and I tried the following:
java oracle.xml.jaxb.orajaxb -schema entity.xsd -targetPkg stuff
using the following CLASSPATH:
c:\jdev\lib\xmlparserv2.jar;c:\jdev\lib\xschema.jar;c:\jdev\xdk\lib\xml.jar;c:\j2sdk1.4.2_01\lib\tools.jar;c:\
jdev\lib
and got this error message:
XML-32011: (Error) a problem was encountered because an abstract complex type "Entity" is referenced from the element "e
ntity-elem".
and I think it's due to the line in entity.xsd:
<xsd:element name="entity-elem" type="Entity" abstract="true"/>
where Entity is defined as follows:
<xsd:complexType name="Entity" abstract="true">
<xsd:sequence>

<xsd:element name="uid" type="xsd:string" minOccurs="1" maxOccurs="1" nillable="true"/>
<xsd:element name="entity-type" type="xsd:string" minOccurs="1" maxOccurs="1"/>
<xsd:element ref="property-value" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
Suggestions welcome...

Generating xml from xsd automated

with jdev i can generate a xml dummy document from some xsd-source. i want to do the same in a java program. is there by any chance a (the) library where i can access such a method? i know about jaxb class generation, but that is not what i need.
thanks

i propably didnt make myself clear enough, sorry about that. :)
your link (jaxb):
1. generate java classes (beans)
2. write some code calling all the right setter-methods of the generated classes to fill your xml-object.
what i need:
1. write one method as explained in my earlier posting
2. compile once, use infinitly for many many different xsds without the need for further coding or recompiling.
why jaxb doesn't fulfil my requirements?
1. you have to generate classes for each new xsd you want a xmlsample for.
2. you have to write new code, calling the correct setters of the generated classes. each time you have a different xsd.

How to generate XML from XML schema

Hi,
I have registered XML schema and I would like to construct XML document for the schema. I wonder it is possible to create an empty instance and then populate it with the data? One solution is to construct the XML with concatenation of the elements but I think it exists more flexible and intelligent way. I read OTN and Metalink samples, documentation and forums users examples but I did not find any appropriate. What is the ordinary way for XML construction? Can you give me some advice? Tank you in advance.
Best regards,
Georgi

The JAXB Class Generator generates java classes with the
orajaxb utility.
oracle.xml.jaxb.orajaxb -schema <schemafile> -outputDir <outputdir>
The java classes generated have get/set methods to construct an XML document.

How to add doctype when generating XML from an arbitrary data structure

I was reading SUN's tutorial "Working with XML - PART IV: Using XSLT". Inside this tutorial, in 3, it talks about how to generate XML from an arbitrary data structure making use of a XMLReader and a Transformer. The example only shows adding elements. Is there a way to add DTD information in the XML generated, i.e. <!DOCTYPE ... >? What APIs can I use?
Thanks,
Alex

The simplest way seems to me is to use a XSL file for that. The <xsl:output> attributes doctype-system and doctype-public generate the DTD declaration <!DOCTYPE YOUR_ROOT SYSTEM "yourDTDfile.dtd"> and <!DOCTYPE YOUR_ROOT PUBLIC "yourDTDfile.dtd">, respectively.
When calling transformerInstance.transform() the XSLT processor performs the identity transformation - it just copies elements, attributes, content, processing instructions and comments to the result stream.
If you're using an xsl file for your transformation already, simply add <xsl:output doctype-system="yourDTDfile.dtd"/> to your existing XSL file.
If you're only using the identity transformation you'd need to change the line of code where you obtain the transformer instance from the TransformerFactory to:
t_factory.newTransformer(new StreamSource("test.xsl"));
and use this as test.xsl:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
   <xsl:output doctype-system="yourDTDfile.dtd"/>
   
   <xsl:template match="*|@*|comment()|processing-instruction()|text()">
      <xsl:copy>
         <xsl:apply-templates select="*|@*|comment()|processing-instruction()|text()"/>
      </xsl:copy>
   </xsl:template>
</xsl:stylesheet>Good luck.

How to generate XML file based on XSD in SSIS

please provide step by step process to create xml based on XSD in SSIS

Hi hemasankar,
In SQL Server Integrated Services, we can generate XML Schema (XSD) file based on a XML file with XML Source Editor. If we want to generate XML file based on a XSD file, we can use Generate Sample XML feature in Visual Studio. For more details, please refer
to the following steps:
Click on "XML Schema Explorer" or 'Use the XML Schema Explorer...' to open XML Schema Explorer in Visual Studio.
If your Schema file is valid and you are having elements, right-click on element and click on "Generate Sample XML", this functionality generates XML file in temp folder and open ups in the XML Editor.
The following two document about how to generate XML file based on a XSD file are for your reference:
http://msdn.microsoft.com/en-us/library/dd489258.aspx
http://www.codeproject.com/Articles/400016/Generate-Sample-XML-from-XSD
If there are any other questions, please feel free to ask.

How to generate XML data from Lotus Notes to migrate to SharePoint by passing XML to SharePoint.?

How to generate XML data from Lotus Notes to migrate to SharePoint by passing XML to SharePoint.?
Ramesh S

You could use XMLQuery to return the data from your tables as XML, that would give you a CLOB.
An example using the SCOTT schema might be like this:
SELECT XMLQuery(
         'for $i in ora:view("DEPT")/ROW
          return <Department dname="{$i/DNAME}">
                 <Employee>
                   {for $j in ora:view("EMP")/ROW
                    where $j/DEPTNO eq $i/DEPTNO
                    return ($j/ENAME, $j/JOB, $j/SAL)}
                 </Employee>
                 </Department>'
         RETURNING CONTENT) FROM DUAL;In the docs you can find more information about its use:

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;

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
