XML Data Model

For standard SA8250 operations, XML data consists of three

hierarchical components or nodes:

• Elements (data types)

• Attributes (subcategories of a data type or element)

• Text (specific data such as names, addresses, and quantities)

NOTE: We indented

XML commands for ease

of reading in this

document. However, the

leading spaces or tabs

are not significant.

The relevant content of an XML document is defined within these

three components. This example shows a block of incoming XML

text as received by the SA8250:

<name lastName="Smith" firstName="John"

initial="K"/>

<id eid=”12345678” jobClass=”System

Engineer”/>

<medicalCarrier>MedCo</medicalCarrier>

</benefits>

<street>13280 Evening Creek Dr</street>

<city>San Diego</city>

<state>California</state>

</address>

</employee>

Where:

•

employee, name, id, benefits, grade, address,

street, city, state,

and zip are elements of the XML

document.

•

lastName, firstName, and initial are attributes of the

name element.

•

eid and jobClass are attributes of the id element.

•

13280 Evening Creek Dr, San Diego, California,

and 92128 are text components of the street, city,

state,

and zip elements, respectively.

XML expressions configured in the SA8250 are matched against

items as shown above and routed for fulfillment according to server

assignments.
