Generating XMLfrom XSD at runtime [message #563376]

Hello All,

I Have got a requirement where we have to generate an xml conforming to a particular XSD.
What i will be having already in place is an XSD document.
We are thinking of making a procedure which will be recieving the set of inputs required for creating that xml.(Data content of that XML.)We would have to make the XML according to that XSD.

Everytime Parsing the XSD is not feasible.
We are looking at a solution which would be easy to make the xml from xsd at runtime.
These values (DATA) will be available at run time.

Thanks in Advance!!!!

I am thinking that maybe you are looking for something with dbms_xmlschema that generates the tables. To clarify your problem, can you post a simple test case that produces something like what you have and also provide an example of what you want based on that?

hi,
Consider an example :

Suppose the XSD is :

<?xml version="1.0" encoding="ISO-8859-1" ?>
<xs:schema xmlns:xs="[url]http://www.w3.org/2001/XMLSchema[/url]">

<xs:element name="shiporder">
  <xs:complexType>
    <xs:sequence>
      <xs:element name="orderperson" type="xs:string"/>
      <xs:element name="shipto">
        <xs:complexType>
          <xs:sequence>
            <xs:element name="name" type="xs:string"/>
            <xs:element name="address" type="xs:string"/>
            <xs:element name="city" type="xs:string"/>
            <xs:element name="country" type="xs:string"/>
          </xs:sequence>
        </xs:complexType>
      </xs:element>
      <xs:element name="item" maxOccurs="unbounded">
        <xs:complexType>
          <xs:sequence>
            <xs:element name="title" type="xs:string"/>
            <xs:element name="note" type="xs:string" minOccurs="0"/>
            <xs:element name="quantity" type="xs:positiveInteger"/>
            <xs:element name="price" type="xs:decimal"/>
          </xs:sequence>
        </xs:complexType>
      </xs:element>
    </xs:sequence>
    <xs:attribute name="orderid" type="xs:string" use="required"/>
  </xs:complexType>
</xs:element>

</xs:schema>

The values for name ,address,and all elements will be known at run time .Now we need to have a code which will generate an xml based on that values.
I know only the structure of xsd.

Also the code needs to be generic handling all possible types of XSD's i.e If any future any new XSD comes then my code should not change.

Please provide an example of the xml that you want based on the xsd provided, as previously requested.

Sorry, but it looks like what I was thinking isn't going to work. Hopefully, someone else will have an idea.
