RE: Problem with a W3C XML Schema


xsd schema nillable
Title: RE: Problem with a W3C XML Schema

You had not defined elements within a sequence, choice or all tag, plus your types were not namespaced prefixed.
Below is the corrected version.

Regards,

Jon Barwell

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:stns="java:examples.newTypes" targetNamespace="java:examples.newTypes" elementFormDefault="qualified" attributeFormDefault="qualified">

        <xsd:complexType name="xorder">
                <xsd:sequence>
                        <xsd:element name="xorderID" type="xsd:string" nillable="true"/>
                        <xsd:element name="xorderDate" type="xsd:dateTime" nillable="true"/>
                        <xsd:element name="xrequest" type="stns:requesttype"/>
                        <xsd:element name="xproduct" type="stns:producttype" minOccurs="0" maxOccurs="unbounded"/>

Subject: Problem with a W3C XML Schema


I have written this W3C XML Schema for Orders

<xsd:schema
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:stns="java:examples.newTypes"
attributeFormDefault="qualified"
elementFormDefault="qualified" targetNamespace="java:examples.newTypes">
        <xsd:complexType name="xorder">
                <xsd:element name="xorderID" type="xsd:string" nillable="true">
        </xsd:element>
                <xsd:element name="xorderDate" type="xsd:dateTime" nillable="true">
        </xsd:element>
                <xsd:element name="xrequest" type="requesttype"/>
                <xsd:sequence>
                        <xsd:element name="xproduct" type="producttype" minOccurs="0" maxOccurs="unbounded"/>
                </xsd:sequence>
        </xsd:complexType>
        <xsd:complexType name="requesttype">
                <xsd:element name="xrequestID" type="xsd:string"/>
                <xsd:element name="xrequester" type="xsd:int"/>
        </xsd:complexType>
        <xsd:complexType name="producttype">
                <xsd:element name="xproductID" type="xsd:string"/>
                <xsd:element name="xproductName" type="xsd:string"/>
                <xsd:element name="xproductPrice" type="xsd:float"/>
        </xsd:complexType>
</xsd:schema>

I am getting error at this line
<xsd:element name="xorderID" type="xsd:string"
nillable="true">

The Schema does'nt appear to be valid. Invalid element xsd:element at this position.

What could be the problem? And how to correct it?

Regards,
Mukul
