Delete parent node based on its child node value in XML

Question

I have an xml like this:
<UPLOAD_REQUEST>
     <CUSTOMER_DETAIL>
     <NAME>Smith</NAME>
     <AGE>20</AGE>
     <GENDER>M</GENDER>
     </CUSTOMER_DETAIL>
     <CUSTOMER_DETAIL>
     <NAME>Nikita</NAME>
     <AGE>35</AGE>
     <GENDER>F</GENDER>
     </CUSTOMER_DETAIL>
</UPLOAD_REQUEST>
I want to delete CUSTOMER_DETAIL node where name = 'nikita' from xml. Also note that there is no identification number for CUSTOMER_DETAIL node.
I was trying to do it like this:
UPDATE request_xml
SET request= deleteXML(request, '/UPLOAD_REQUEST/CUSTOMER_DETAIL')
WHERE extractvalue(request, '/UPLOAD_REQUEST/CUSTOMER_DETAIL/NAME') = 'Nikita';
It gives error "*EXTRACTVALUE returns value of only one node*"
Final output should be
<UPLOAD_REQUEST>
     <CUSTOMER_DETAIL>
     <NAME>Smith</NAME>
     <AGE>20</AGE>
     <GENDER>M</GENDER>
     </CUSTOMER_DETAIL>
</UPLOAD_REQUEST>
Can anyone please help me how to do this?

Answer 1

Add a predicate in the XPath expression :
UPDATE request_xml
SET request = deleteXML(request, '/UPLOAD_REQUEST/CUSTOMER_DETAIL[NAME="Nikita"]')
;
