1. 1. A per our business logic we have created rule(Xquery) and we are evaluating this with the help of evaluate method.

2 XQuery:

let $gReturnDataState := element{'ReturnDataState'} {''}

let $gSchA...................

for

$ReturnDataState at $currentReturnDataStatePos in if(....................

let $genSchA := false()

let $genAllRealTangibleProperty...........

<Evaluation><FieldEntry>

<Name>x:AllPropEndYrTotal</Name>

<Xpath>x:ReturnState/x:ReturnDataState/x:SchA/x:AllRealTangibleProperty/x:AllPropEndYrTotal</Xpath>

<Value>{$AllPropEndYrTotalData}</Value>

<NextValue></NextValue>

....................................

<NodeIsPresent></NodeIsPresent>

<HasChildNodes></HasChildNodes>

</FieldEntry></Evaluation>

Code:

XdmValue evaluations = evaluator.Evaluate();

3. For few rules XQuery execution takes greater than 30GB memory.
