  3. XML Document in Word • Let's have a look at this XML document called “Simple.xml” • XML document has a root element persons. • The “persons” element contains 1 child element “person”. • “person” appears twice and contain name, address, city, and country elements. Tariq Aziz, Dammam Community College

  4. XML Document in Notepad <?xml version="1.0" encoding="ISO-8859-1"?> <persons xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="simple.xsd"> <person> <name>Ola Nordmann</name> <address>Langgt 23</address> <city>4000 Stavanger</city> <country>Norway</country> </person> </persons> Tariq Aziz, Dammam Community College

  5. XML Document • The line above: xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" tells the XML parser that this document should be validated against a schema. • The line: xsi:noNamespaceSchemaLocation="simple.xsd" specifies WHERE the schema resides (here it is in the same folder as "simple.xml"). Tariq Aziz, Dammam Community College

  6. Create XML Schema • Open a file in Notepad and name it “Simple.xsd” • To create the schema we could simply follow the structure in the XML document and define each element as we find it. • We will start with the standard XML declaration followed by the xs:schema element that defines a schema <?xml version="1.0" encoding="ISO-8859-1" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> ... ... </xs:schema> Tariq Aziz, Dammam Community College

  7. Create XML Schema[2] <?xml version="1.0" encoding="ISO-8859-1" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> ... ... </xs:schema> • In the schema above we use the standard namespace (xs), • The URI associated with this namespace is the Schema language definition, which has the standard value of http://www.w3.org/2001/XMLSchema. Tariq Aziz, Dammam Community College

  8. Complex Type • Next, we have to define the “persons" element. • This element contains other elements, therefore we consider it as a complex type. • The child elements of the “person" element is surrounded by a xs:sequence element that defines an ordered sequence of sub elements <xs:element name="persons"> <xs:complexType> <xs:sequence> ... ... </xs:sequence> ... </xs:complexType> </xs:element> Tariq Aziz, Dammam Community College

  9. SML Schema <?xml version="1.0" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="persons"> <xs:complexType> <xs:sequence> <xs:element name="person"> <xs:complexType> <xs:sequence> <xs:element name="title" type="xs:string" /> <xs:element name="note" type="xs:string" /> <xs:element name="quantity" type="xs:positiveInteger" /> <xs:element name="price" type="xs:decimal" /> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> Tariq Aziz, Dammam Community College
