Duplicate keys filtering in Dataweave - filter

Question

I have a requirement to read the 'Pronoun' value from the below XML data.
in this scenario wd:ID is the duplicate key and I need to read <wd:Value> attribute under <wd:Integration_Field_Override_Data> object which has <wd:ID> = 'Pronoun'
<?xml version="1.0" encoding="UTF-8"?>
<wd:Get_Workers_Response xmlns:wd="urn:com.workday/bsvc" wd:version="v33.0">
<wd:Response_Data>
<wd:Worker>
<wd:Worker_Data>
<wd:Worker_ID>1129</wd:Worker_ID>
<wd:User_ID>126</wd:User_ID>
<wd:Integration_Field_Override_Data>
<wd:Field_Reference>
<wd:ID wd:type="WID">916f7f9977422e610e634</wd:ID>
<wd:ID wd:type="Integration_Document_Field_Name" wd:parent_type="Integration_Document_Name" wd:parent_id="INT005 - OVERRIDE SERVICE - WORKER">Position as of Hire</wd:ID>
</wd:Field_Reference>
<wd:Value>0086186</wd:Value>
</wd:Integration_Field_Override_Data>
<wd:Integration_Field_Override_Data>
<wd:Field_Reference>
<wd:ID wd:type="WID">916f7f969d1b57422e610e734</wd:ID>
<wd:ID wd:type="Integration_Document_Field_Name" wd:parent_type="Integration_Document_Name" wd:parent_id="INT005 - OVERRIDE SERVICE - WORKER">Probation Period Outcome</wd:ID>
</wd:Field_Reference>
</wd:Integration_Field_Override_Data>
<wd:Integration_Field_Override_Data>
<wd:Field_Reference>
<wd:ID wd:type="WID">438411e0d12510b6d9a0000</wd:ID>
<wd:ID wd:type="Integration_Document_Field_Name" wd:parent_type="Integration_Document_Name" wd:parent_id="INT005 - OVERRIDE SERVICE - WORKER">Pronoun</wd:ID>
</wd:Field_Reference>
<wd:Value>He/They</wd:Value>
</wd:Integration_Field_Override_Data>
</wd:Worker_Data>
</wd:Worker>
</wd:Response_Data>
</wd:Get_Workers_Response>
I have added a below filtering logic to retrieve 'Pronoun' value however it may impact if they change the order while generating Pronoun ID.
Can you please help me with better approach to perform this action.
var pronounData = (worker.Worker_Data.*wd#Integration_Field_Override_Data filter((item, index) -> item.Field_Reference..*ID[1] == 'Pronoun')) default null
And retrieve pronoun value as
pronoun: pronounData[0].Value
Expected Output --> "He/They"

Answer 1

You can change the condition of the filter to check if the array of IDs contains the desired string.
Example:
%dw 2.0
output application/java
ns wd urn:com.workday/bsvc
---
(payload.wd#Get_Workers_Response.wd#Response_Data.wd#Worker.wd#Worker_Data
.*wd#Integration_Field_Override_Data
filter((item, index) -> item.Field_Reference..*ID contains 'Pronoun'))[0].wd#Value
Note that the default clause is redundant since the expression already returns null if the desired string is not found.
