XML Data Services

Change in Mindset

- 9 -

We focus on the “Data”.

Read and Write the “Data” with different parsers.

XML complicates the Business logic.

Validate XML using XML Schema (XSD).

XML Parsing

<?xml version="1.0"?>

<xsd:schema>

<xsd:element name="dsCustomer">

<xsd:complexType>

<xsd:sequence>

<xsd:element name="eCustomer" minOccurs="0" maxOccurs="unbounded“ >

<xsd:complexType>

<xsd:sequence>

<xsd:element name="CustNum" type="xsd:int" nillable="true" />

<xsd:element name="Name" type="xsd:string" nillable="true" />

<xsd:element name="Phone" type="xsd:string" nillable="true” />

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