DTD for Address XML
<?xml version="1.0" encoding="UTF-8"?>
<!ELEMENT address (street+, city, state, zip)>
<!ELEMENT street (#PCDATA) >
<!ELEMENT city (#PCDATA) >
<!ELEMENT state (#PCDATA) >

4. DTD vs XSD contd..
• XSD for Address XML
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:fc="http://www.friendzcorp.com/OracleSoabook"
targetNamespace="http://www.friendzcorp.com/OracleSoabook">
<element name="address" type="fc:Address" />
<complexType name="Address">
<sequence>
<element name="name" type="string" />
<element name="street" type="string" />
<element name="city" type="string" />
<element name="state" type="string" />
<element name="zip" type="string" />
</sequence>
</complexType>
</schema> muraliksoa@gmailcom

5. • Address instance based on address XSD
<?xml version="1.0" encoding="UTF-8"?>
<addr:address
xmlns:addr="http://www.friendzcorp.com/
OracleSoabook">
<name>Murali</name>
<street>1st street</street>
<city>Hyderabad</city>
<state>Andhra Pradesh</state>
<zip>500045</zip>

7. Nested complex types:
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:fc="http://www.friendzcorp.com/OracleSoabook"
targetNamespace="http://www.friendzcorp.com/OracleSoabook" >
<element name="purchaseOrder" type="fc:PurchaseOrder" />
<element name="address" type="fc:Address" />
<complexType name="PurchaseOrder">
<sequence>
<element name="accountName" type="string" />
<element name="accountNumber" type="unsignedShort" />
<element name="shipAddress" type="fc:Address" />
<element name="billAddress" type="fc:Address" />
<element name="book" type="fc:Book" />
<element name="total" type="float" />
</sequence>
</complexType>
<complexType name="Address">
<sequence>
<element name="name" type="string" />
<element name="street" type="string" />
<element name="city" type="string" />
<element name="state" type="string" />
<element name="zip" type="string" />
</sequence>
</complexType>

8. Sample XSDs Contd..
Usage of Occurrence constraints:
<complexType name="Address">
<sequence>
<element name="name" type="string" />
<element name="street" type="string"
minOccurs="1" maxOccurs="2" />
<element name="city" type="string" />
<element name="state" type="string" />
<element name="zip" type="string" />
</sequence>
