Constructing XML from XSD dynamically

HI All.,
can any one tell me how to generate a xml file with the given xsd (we don't know abt xsd ,this can be any type of xsd).this means dynamic generation of xml file with the given xsd using java.
More Explanation abt the problem:
Bye pointing the path xsd file..we need to show them an sample xml file.
any suggestion highly appreciated.
Thanks
Kim.

The simplest approach would be to take the XSD, run it through JAXB, use reflection to populate the generated objects, and then marshall to XML. However, there are likely to be a number of edge cases where this will fail. It's also fairly straightforward to parse the XSD and construct a transformation engine that does the right thing for simple XML, but again, the edge cases (think xsd:choice will cause problems).
However, I can't help but wonder if this is really useful? While you can auto-generate syntactically valid documents, there's also semantic meaning that would be important to anyone using those documents. Throwing a random string of characters into an element defined as xsd:string probably isn't going to be useful if you want to generate XML containing a name and address.

Can not construct xml from relative xpath expression: //FormVar

In version 7.0, it was possible to access Form Variables with the (valid) XPath Expression "//FormVariable".
In 7.2.2, using this XPath Expression leads to a stalled action, with message: "can not construct xml from relative xpath expression: //FormVar". (see full stack trace below)
What's wrong? How can I fix this?
Use of relative expression is very very useful during the development phase!

Sorry, i just read my own message in the discussion forum and
discovered all spaces for formating the XML tags where gone.
It should look like this:
[-----xml_type---]
<doc>
__<role>
____actor
____<first>
______john
____</first>
____<last>
______bond
____</last>
__</role>
__<role>
____actor
____<first>
______james
______</first>
____<last>
______smith
____</last>
__</role>
</doc>
semantic:
There are two actors: "john bond" and "james smith"
Querying for "john bond" succeedes which is correct
Querying for "james smith" succeedes which is correct
Querying for "james bond" fails which is correct
Querying for "john smith" succeedes which is an ERROR!
contains(xdata, 'actor INPATH(//role[./first = "john" and ./last
= "smith"])' (= 100 ---> ERROR!)
bye,

Create XML from XSD

Hi,
Is it possible to create and populate XML from an XSD without knowing what the XSD elements are beforehand (all the examples appear to know what the input XSD will be, and therefore know what the set and get methods should be called)?
Can a user browse for an xsd to input, and the java will dynamically create the get methods, and be able to create instances and populate variables before converting to XML?
I have looked at JAXB and the purchase.order examples mainly, and it appears the input XSD was known before writing the java to populate the variables.
Thanks
John

Hi,
Is it possible to create and populate XML from an XSD
without knowing what the XSD elements are beforehand
(all the examples appear to know what the input XSD
will be, and therefore know what the set and get
methods should be called)? I think it is possible--you would have to recompile each time (unless you can dynamically recompile, which would be neat), but using the classes getMethod() function, you can list all the methods. You would then have to do some tricky logic to determine which of the getMethods you want (for example NOT getClass()), and you can basically call them in sequence. You also need to worry about handling lists & recursively call xxxType classes.
I'm experimenting with this, and it can get a little frustrating because there are a lot of odd cases to handle (for example, while setting the elements of a list, you need to actually get the list & add elements to it), but I think it's possible.

What I'm puzzled about is where you'd get the data to populate the variables? Perhaps a database, or a bean? If you just want to make a test xml file, then it doesn't matter, but with real data, I think you'd still have to change how you actually get the variables you want to populate the xml file with, right? In other words, if your schema changed, the parameters you're passing to the set methods would change as well.
Maybe we'll see some more packages in the future to make this task easier.

Creating XML from XSD, Only create The First Element

Hi,
I create a XML File from a xsd schema by this way:
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
          factory.setNamespaceAware(true);
          factory.setValidating(true);
               factory.setAttribute(JAXP_SCHEMA_LANGUAGE,W3C_XML_SCHEMA);
               factory.setAttribute(JAXP_SCHEMA_SOURCE, new File(MY_SCHEMA));
                DocumentBuilder documentBuilder =factory.newDocumentBuilder();
          documentBuilder.setErrorHandler(new SimpleDOMHandler());
          Document parse = documentBuilder.parse(new File(MY_XML));The first lines of the schema:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
     targetNamespace="http://gencat.net/scsp/esquemes/peticion"
     elementFormDefault="qualified" attributeFormDefault="unqualified"
     id="Peticio" xmlns:p="http://gencat.net/scsp/esquemes/peticion">
     <xs:element name="Apellido1">
          <xs:simpleType>
               <xs:restriction base="xs:string">
                    <xs:maxLength value="40" />
               </xs:restriction>
          </xs:simpleType>
     </xs:element>
     <xs:element name="Apellido2">
        .............................The problem is that the created document only have the first element "Apellido1". I dont know if it is a wrong xsd, or i'm using a bad way to do it.
Thanks a lot, and apologize for my english

How to create an xml from xsd in abap

HI Experts,
i want to create an xml file from xsd and i want to validate an xml file against an xds.is this possible in abap.if it is possible can any one give me an sample code
for this one.
how to create an xml file in abap.i have seen so many blogs which parses the xml file but i didn't get blog for creating an xml file.how can we do that one.
any suggestions will be appriciated
thanks in advance
With Regards
Naidu

HI
GOOD
IT IS POSSIBLE IN ABAP
Extensible Markup Language (XML) is a simple, very flexible text format derived from SGML (ISO 8879). Originally designed to meet the challenges of large-scale electronic publishing, XML is also playing an increasingly important role in the exchange of a wide variety of data on the Web and elsewhere.
XSD->
XML Schemas express shared vocabularies and allow machines to carry out rules made by people. They provide a means for defining the structure, content and semantics of XML documents. in more detail.
XDS->
XDS can process data images from CCD-, imaging-plate, and multiwire-detectors in a variety of formats. Detector specific Input file templates greatly simplify the use of XDS; they are provided as part of the documentation.
XDS runs under Unix or Linux on a single server or a grid of up to 99 machines of the same type managed by the MOSIX system; in addition, by using OpenMP, it can be executed in parallel on up to 32 processors at each node that share the same address space.

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.

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.

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.

Generating XML instance from XSD

Hi,
I want to know ( java program etc ) to generate XML instance from XSD. How tools ( XML Spy, Oxygen ) generate sample XML file from XSD. What APIs can be used for generating XML from XSD and what APIs are used for checking If XML instance conforms to a XSD? Is it big deal to implement it?
Thanks in advance
Sandeep

To validate xml against XSD , I found I can use the existing parsers( using JAXP which has SAX and DOM APIs ) in current JDKs and validate. I still did not find the best way to generate xml from XSD and how tools like xml spy and oxygen generates sample xml file from xsd.
Thanks

About generating Java classes from XSD Schema ???

I need a powerfull tool to generate Java classes from XML Schema. I want that generated classes to have the option to validate XML(to be JAXP1.2 compliant).
I used XML Spy 5.4 but the generated classes can't validate an XML file.
Can you help me with other tools that:
- generate Java classes from XSD
- generate sample XML from XSD
- are JAXP1.2 compliant(validate a XML file with a schema)
Thanks.

You can also use Castor: http://www.castor.org
It generates classes from XML Schemas and enables data
binding without writing any line of a fuckin SAX
parser :-)I evaluated Castor and JAXB and while JAXB isn't perfect, it's got some things over Castor. Castor almost looks abandonded when I go to the site. The documentation just sort of trails off.
