Hi all,
I am having problem when did the validation of XML document with Schema.
my schema is like the following:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="schema.xsd"
xmlns:msprop="urn:schemas-microsoft-com:xml-msprop"
elementFormDefault="qualified" targetNamespace="schema.xsd">
<xsd:element name="bookstore" type="bookstoreType" />
<xsd:complexType name="bookstoreType">
<xsd:sequence maxOccurs="unbounded">
<xsd:element name="book" type="bookType" />
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="bookType">
<xsd:sequence>
<xsd:element name="title" type="xsd:string" />
<xsd:element name="author" type="authorName" />
<xsd:element name="price" type="xsd:decimal" />
</xsd:sequence>
<xsd:attribute name="genre" type="xsd:string" />
<xsd:attribute name="publicationdate" type="xsd:string" />
<xsd:attribute name="ISBN" type="xsd:string" />
</xsd:complexType>
<xsd:complexType name="authorName">
<xsd:sequence>
<xsd:element name="first-name" type="xsd:string" />
<xsd:element name="last-name" type="xsd:string" />
</xsd:sequence>
</xsd:complexType>
</xsd:schema>

and the xml file is:
<?xml version='1.0'?>
<!-- This file represents a fragment of a book store inventory database -->
<bookstore xmlns = "schema.xsd">
<book genre="autobiography" publicationdate="1981" ISBN="1-861003-11-0">
<title>The Autobiography of Benjamin Franklin</title>
<author>
<first-name>Benjamin</first-name>
<last-name>Franklin</last-name>
</author>
<price></price>
</book>
<book genre="novel" publicationdate="1967" ISBN="0-201-63361-2">
<title>The Confidence Man</title>
<author>
<first-name>Herman</first-name>
<last-name>Melville</last-name>
</author>
<price>11.99</price>
</book>
<book genre="philosophy" publicationdate="1991" ISBN="1-861001-57-6">
<title>The Gorgias</title>
<author>
<first-name>Sidas</first-name>
<last-name>Plato</last-name>
</author>
<price>9.99</price>
</book>
</bookstore>

when I did the validation, gave me a error saying that
Validation error: The 'schema.xsdrice' element has an invalid
value according to its data type.

I know it is because there is a empty element
<price></price>
in my xml file.
if there any solution to use so that the xml XmlValidatingReader can
recognize the null value?

Thanks.

Lynn

In the schema put the nillable true attribute on the price element like:

<xsd:element name="price" type="xsd:decimal" nillable="true"/>

and in the XML set the xsi:nil=true but you have to map the xsi namespace
first. Your new XML is:

<bookstore xmlns = "schema.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<book genre="autobiography" publicationdate="1981" ISBN="1-861003-11-0">
<title>The Autobiography of Benjamin Franklin</title>
<author>
<first-name>Benjamin</first-name>
<last-name>Franklin</last-name>
</author>
<price xsi:nil="true"></price>
</book>
<book genre="novel" publicationdate="1967" ISBN="0-201-63361-2">
<title>The Confidence Man</title>
<author>
<first-name>Herman</first-name>
<last-name>Melville</last-name>
</author>
<price>11.99</price>
</book>
<book genre="philosophy" publicationdate="1991" ISBN="1-861001-57-6">
<title>The Gorgias</title>
<author>
<first-name>Sidas</first-name>
<last-name>Plato</last-name>
</author>
<price>9.99</price>
</book>
</bookstore>

Thanks Zafar.
That works.
Is that possible that it can work without
xsi:nil attribute?

thanks.

It coudn't because then it will try to validate an empty value against the
data type xs:decimal, it will throw a validation error. If you want to
validate empty value for the price element, them you should have it typed as
xs:string and then put pattern restrictions on ONLY accept numbers and an
empty value.

HTH,

Hi Zafar,All
I am also facing null value problem.can you suggest me a solution.
in my wsdl file i have

<xsd:simpleType name="VehicleType" >
<xsd:annotation>
<xsd:documentation>Defines the available vehicle
types</xsd:documentation>
</xsd:annotation>
<xsd:restriction base="xsd:string">
<xsd:enumeration value="sedan"/>
<xsd:enumeration value="suv"/>
<xsd:enumeration value="van"/>
</xsd:restriction>
</xsd:simpleType>

<xsd:complexType name="Reservation">
<xsd:element maxOccurs="1" minOccurs="0" name="vehicleType"
type="xsd1:VehicleType" nillable="true"/>
</xsd:complexType>

And in my ws-application.xml file:

<mapping>
<schemaType>VehicleType</schemaType>
<javaType>....model.VehicleType</javaType>
<holder>....model.VehicleTypeHolder</holder>
</mapping>

I have placed nillble="true" in wsdl file.
But where can i place xsi:nil="true".
How can i give null.

Awaiting for your reply

siraj.
