XMLType extract method does not work if namespace attribute values are included

Question

In the example below, only the second row returns an ID from the extract function. The presence of an xmlns attribute appears to be the cause.

Hi Amarnath,
Thanks for looking into my issue.
When I started writing the dynamic custom approver group, I did not use FND_NUMBER and it didnt work. After that I checked it in the AME Implementation Guide which says
"Queries for number and currency attributes must select the number or currency
amount converted to a varchar2 by:
fnd_number.number_to_canonical"
So that should not be a problem.
Please correct me if I am wrong but Now I see two different possibilities :
1. The seeded variable :transactionId which is being passed to the query is not able to get the value. In other words, the transactionId is not being passed.
2. I am using wrong Attributes to identify the transaction which is being used in the Condition and that condition is used in a Rule. In this case, I am trying to identify that the Basic Person details are changed and I am using seeded attribute HR_IS_PERSON_BASIC_DETAILS_CHANGE_SS in condition.
Any feedback?
Appreciate all replies.
Thanks,
CAH
