Hi, I think the problem is that XERCES supports http://www.w3.org/2001/XMLSchema-instance and u are using 1999 version
I generated a new schema through XMLSPy tool. Just add the following line to ur xml at census tag xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:noNamespaceSchemaLocation="census1.xsd" Now your validation code should work. Baring that a occupant tag is not closed so, if u are catching Fatalerrors in your ErrorHandler it will generate the exception you. The new schema is pasted below: <?xml version="1.0" encoding="UTF-8"?> <!--W3C Schema generated by XML Spy v4.3 U (http://www.xmlspy.com)--> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; elementFormDefault="qualified"> <xs:complexType name="addressType"> <xs:sequence> <xs:element ref="number"/> <xs:element ref="street"/> <xs:element ref="city"/> <xs:element ref="province"/> </xs:sequence> </xs:complexType> <xs:element name="age"> <xs:simpleType> <xs:restriction base="xs:byte"> <xs:enumeration value="22"/> <xs:enumeration value="52"/> <xs:enumeration value="61"/> </xs:restriction> </xs:simpleType> </xs:element> <xs:element name="census"> <xs:complexType> <xs:sequence> <xs:element ref="censustaker"/> <xs:element name="address" type="addressType"/> <xs:element name="occupants" type="occupantsType"/> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="censustaker" type="xs:short"/> <xs:element name="city" type="xs:string"/> <xs:element name="firstname"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="Filbert"/> <xs:enumeration value="Floyd"/> <xs:enumeration value="Phylis"/> </xs:restriction> </xs:simpleType> </xs:element> <xs:element name="number" type="xs:short"/> <xs:complexType name="occupantType"> <xs:sequence> <xs:element ref="firstname"/> <xs:element ref="surname"/> <xs:element ref="age"/> </xs:sequence> <xs:attribute name="status" type="xs:string"/> </xs:complexType> <xs:complexType name="occupantsType"> <xs:sequence> <xs:element name="occupant" type="occupantType" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> <xs:element name="province" type="xs:string"/> <xs:element name="street" type="xs:string"/> <xs:element name="surname" type="xs:string"/> </xs:schema> Regards, Pavitra Jain -----Original Message----- From: Ramin Raybod [mailto:[EMAIL PROTECTED] Sent: Monday, April 29, 2002 9:22 AM To: xerces Subject: An example of schema Hi, I'm so new to xml schema and am reading Oreilly "Learning XML" e-book from "Safari Tech Books Online". There is an example of a schema at the end of chapter 5 of the book. I tried to validate it by xerces through a sample validation program called sax.SAXCount. It has too many errors like it is not a valid schema at all. I guess it is because of version used in this example - 1999. I compared this with another schema a sample coming with xerces set - 2001 version . Wow too much difference. How? Is there really no support for such schema mentioned in this book? or I have problems in using something? Anyway I have written the sample schema and the related xml doc here. Oh yes I had to add some additional code to XML file for linking to the schema file... I have deleted an attribute also... These are the differences I've made to the original example of the book :) Thanks Ramin --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
