How read a XML Schema

Hi,
i wish to ask you a question: how i can read a XML Schema? Which library i have to use to visit a XML Schema? There are examples on internet? I haven't found anything about it.
Please help me.
Thank you, regards
Gianni

WXS schemas and RelaxNG schemas have an XML encoding, so any XML parser can read them. ASN1 XML schemas and compact RNG schemas require specialist parsers.
If you wish to populate a more useful structure than DOM, then Castor has classes to represent and manipulate WXS, though I've not used them myself.

PL/SQL web service - how to use XML schema to define inputs/outputs?

Hello,
let us say I want to publish a PL/SQL web service. The package spec that I want to expose is:
CREATE OR REPLACE PACKAGE myWebService AS
FUNCTION loadResults(
    username   IN VARCHAR2,
    password   IN VARCHAR2,
    resultData IN XMLType)
RETURN XMLType;
END;When I use JDeveloper's wizard to publish my PL/SQL web service, the resulting WSDL contains this:
<schema
    xmlns="http://www.w3.org/2001/XMLSchema"
    xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"

            </sequence>
        </complexType>
    </element>
</schema>It is specifying that anything at all can be passed in and out from the two XMLType arguments, which is fair enough: it has no way of knowing what I am expecting and what I shall return.
My question is, how do I tell JDeveloper that actually I want either or both of those XMLTypes to conform to a particular XML schema?

You cannot format the date as a string, unless you do the conversion on the PL-SQL side, before you use it in your WebService mapping. It should be handled as a string.
The only way to convert the XML from SOAP, using this encoding, into literal XML is to apply XSLT to the payload. Not sure why you would like to do this, as the payload should be consumed by another SOAP-awared stack.
Hope this helps,

How to change XML Schema in MDM Console?

Hi Experts,
My scenario: SRM send products to MDM Catalog using PI.
I need to change the XML Schema (XSD) for processing some new fields that don't exist in Catalog. So I created a copy of the XSD file in my station and made the necessary changes.
In XML Schema (MDM Console), I changed the FileName for getting the XSD I created.
But when I tested SRM Shopping Cart again, this couldn't access the products in Catalog anymore.
1) After my chage the FileName shows the name with "c:\Documents and Settings\...". Does it work?? Is this the cause of the error?
2) Do you know why my change affect the Shopping Cart access to the products in the Catalog?
3) Now I don't know how to undo my change in FileName. I can't do it because in the FileName MDM Console it doesn't allow to write it. It allows only to choose a file in some place, my station for example.
Could anyone help me?
Thanks!
Rose

Hi Kanstantsin,
I was analysing what you explain, but it was not exactly this problema. But what you wrote, help me to understand better the MDM and lets me know more about schemas .
Thank you very much for your help.
Hi Vinary,
It was exactly this. I had edited the name. I changed it and now it is working.
Thank you very much for your help!

3rd party integration: How to get XML Schema (.xsd) for a custom entity, to use with a mapper

Is there an easy way to get the xml schema/DTD for a custom entity, specifically an .XSD file for that entity (which will then be used to create a map to be able to transform the fields of the entity to a 3rd-party message format)?
So have a custom entity with lots and lots of fields. Each of the fields will map to a differently named field to match the schema of the 3rd party entity. A very common situation. Looking to use a tool like the Biztalk mapper or Altova's MapForce to generate
an .xslt file to transform the downloaded entity (service.Retrieve with all columns) to the new format. (Will implement a typical VETR pattern.)
Apparently with CRM 4 there was a call that provided this, but from 2011 has not been available. Working with a crm 2015 system.

That will give a descriptor of the table and allow creation of an .XSD file, but it's really complex in terms of types, and the there's type conversion. It might be an easy way to get a schema, with the downside being it's hard to use that schema.
It seems easier to do a fetch of the record with all fields filled in using service.Retrieve, and then converting this to xml, using Microsoft's guidance leads to using https://msdn.microsoft.com/en-us/library/hh675409.aspx which will serialize the entity
into XML with all the fields converted to type string, and with complex fields likewise converted to strings with additional information about the type.
Using this it's possible using an number of tools to create an easier to use .XSD file.
However, it would seem most integrations of this type are using 3rd party CRM connectors. Perhaps this is why Microsoft hasn't provided anything direct (and took away what they did have in crm4.0 due to it generating a hard to use .XSD or due to letting
their partners continue income streams from selling connectors").
But without using 3rd party connectors, or following the still tedious method of generating .XSD (a useable .xsd), have not yet come up with an easy, automatic way to get an .XSD or to easily integrate with 3rd party message format.

How many W3C XML Schema grammars are currently supported in JAXB ?

JAXB supports for a subset of W3C XML Schema and XML Namespaces.
So is there a list of what kind of grammars of W3C XML Schema are currently supported, and what are not support? For example, is xsd:list or xsd:union support?
Thanks!

Refer to 'What is Not Supported' in JAXB.

How Does FrameMaker Support XML Schemas?

Hi All,
I'm wondering how FM supports XML Schemas. I need to validate the uniqnuess of the value of an element in my XML. Let's say I have an XML like this one:
<Param>
     <name>Parameter 1 name</name>
     <description>Parameter 1 description</description>
     <code>12345</code>
</Param>
<Param>
     <name>Parameter 2 name</name>
     <description>Parameter 2 description</description>
     <code>6789</code>
</Param>
The value of <code> must be unique throughout the XML file. As far as I know, I can add a validation of the uniqnuess of <code> into my XML schema. The question is whether this uniqnuess check will be supported by FM.
Any advice is appreciated.
Thank you very much!

It should (though I have not tested it myself). Framemaker 11 uses XercesC 2.7 for parsing the incoming/outgoing XML and it supports unique constrains. EDD cannot check the possible violation, however.

[JAXB 2.x] Defining the XML Schema Type for XmlElementDecl

How can an XML Schema Type (XmlSchemaType) be defined for an XmlElementDecl/Ref?
The classes are as follows:
    @XmlRegistry
    class ObjectFactory {
        // XmlSchemaType is desired, but cannot be used with XmlElementDecl/Ref: @XmlSchemaType(name = "unsignedShort")
        @XmlElementDecl(namespace = "urn:com:test:namespace", name = "char", scope = com.test.Arguments.class)
        @XmlJavaTypeAdapter(com.test.CharacterAdapter.class )
        public JAXBElement<Character> createArgumentsChar(Character value) {
            return new JAXBElement<Character>(_ArgumentsChar_QNAME, Character.class, com.test.Arguments.class, value);
    @XmlAccessorType(XmlAccessType.FIELD)
    @XmlType(name = "", propOrder = { "arguments" })
    class Arguments {
        @XmlElementRefs( {
                @XmlElementRef(name = "char", namespace = "urn:com:test:namespace", type = JAXBElement.class),
        protected List<JAXBElement<?>> arguments;
    }The desired schema is as follows:
    <xs:element name="arguments" minOccurs="0">
        <xs:complexType>
            <xs:sequence>
                <xs:choice minOccurs="0" maxOccurs="unbounded">
                    <xs:element name="char" type="xs:unsignedShort" />
                </xs:choice>
            </xs:sequence>
        </xs:complexType>
    </xs:element>However, when generating the schema from these classes (schemagen), the resulting "char" element type is "xs:string," not "xs:unsignedShort" as desired. What annotation can be used to indicate that the type should be xs:unsignedShort? If the addition of an annotation is not possible, are there any other ways to accomplish this?

There are mappings between XSD type and Java type table on the Sun website.

Memory issue loading XML schema files

Hi,
I have an application that a startup reads available XML schema files from a folder and creates Validator objects that are put into a HashMap.
I'm running into problems creating validation schema objects when the file size of the schema is just over 30kB in size.
The following error message is given when testing with the "large" schemas:

The smaller 1-10kB schemas can be stored without any problem regardless of the number I test (+1000).
The problem occurs as soon as it handles these larger schemas in the source directory. Even only one 30kB schema is enough to consume the all memory.
Below is the code uesd for creating the validation objects

The smaller 1-10kB schemas can be stored without any problem regardless of the number I test (+1000).
The problem occurs as soon as it handles these larger schemas in the source directory. Even only one 30kB schema is enough to consume the all memory.Are you certain that only one schema is involved? How does the code tell how many schemas there are?
Below is the code uesd for creating the validation objects
for(int i=0;i<files.length;i++){
SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Source schemaFile = new StreamSource(files);
schema = factory.newSchema(schemaFile); // Here is where the process fails
Validator validator = schema.newValidator();
hm.put(documentType, validator); //hm is the HashMap used as placeholder for Validator objects
It would seem that if files.length is 10000, that would end up in around 30 times as much memory usage as for the 1000x10Kb schemas.

Xml schema Vs DTD

Hi,
Can some one please give me a pointer or elaborated detail regarding how using xml schema helps instead of using DTDs and the most popular and efficient tool out there that converts DTDs into XSDs? I know there is some inforamtion about this in W3C documents, anything more consice than the W3C documents will help.
Thanks,

I use Altova XML Spy. This editor is used in many examples in the Oracle Documentation.
