Hi Pragya,

try below sample code

let $sorting :=<a> <sorting>

<columnAlias>Currency</columnAlias>

</sorting>

<columnAlias>AgreementType</columnAlias>

</sorting>

<columnAlias>CollectionNo</columnAlias>

</sorting></a>

let $results :=

<title>Currency</title>

<title>AgreementType</title>

<title>CollectionNo</title>

</columns>

<Currency>US dollar</Currency>

</result>

<Currency>Pound sterling</Currency>

</result>

</result>

</results>

</report>

return if($sorting/sorting/sort) then

for $each in $results//results/result

order by $each/AgreementType descending , $each/CollectionNo ascending

return $each (: modify as per your business requirement :)

else $results

Hi,

I need to sort the $results based on element columnAlias in $sorting.

for eg :

In the below scenario, I want to first sort the $results with AgreementType(desc) and then with CollectionNo(asc).If there is not <sort> element in $sorting/sorting then do not use that element <columnAlias> for sorting.

Moreover the elements in $sorting & $results will be dynamic and not fixed.

let $sorting :=<a> <sorting>

<columnAlias>Currency</columnAlias>

</sorting>

<columnAlias>AgreementType</columnAlias>

</sorting>

<columnAlias>CollectionNo</columnAlias>

</sorting></a>

let $results :=

<title>Currency</title>

<title>AgreementType</title>

<title>CollectionNo</title>

</columns>

<Currency>US dollar</Currency>

</result>

<Currency>Pound sterling</Currency>

</result>

</result>

</results>

</report>

Thanks

Pragya
