A common case of such circumstances is when an expression only accesses the previous array index, such as maintaining a running sum of an array of integers. The following schema describes this, but provides a hint that only one previous array index is needed by an expression:
| Code Block | ||
|---|---|---|
| ||
<xs:element name="arr" maxOccurs="unbounded" dfdlx:previousArrayIndiciesRequired="1">
<xs:complexType>
<xs:sequence>
<xs:element name="int" type="xs:int" ... />
<xs:element name="runningSum" type="xs:int"
dfdl:inputValueCalc="{
if (dfdl:occursIndex() eq 1)
then ../int
else ../int + ../../arr[dfdl:occursIndex() - 1]/runningSum
}" />
</xs:sequence>
</xs:complexType>
</xs:element> |
