extracting all tags(duplicates also) with specified name from xmltype column in sql - sql

Question

i want to extract a tag from an xml and insert into another table.
this XML is having different name spaces hence i use local-name() to fetch the tag which i want.
but some times there are multiple tags with same name. hence its failing with EXACTFETCH RETURNS MULTIPLE NODES. when multiple tags are existed i want to consider both instead of ignoring the second occurence.
source_table(id, payload):
id : 10
payload :
<root>
<name>john</name>
<status>
<statuscode>1</statuscode>
<statusmessage>one</statusmessage>
<statuscode>2</statuscode>
<statusmessage>two</statusmessage>
</status>
</root>
i want to extract stauscode and message and insert into another table
destination_table(id,name,statuscode,message)
output
10,john,1,one
10,john,2,two
below is the query i used
select id,
extract(payload, '//*[local-name()="name"]'),
extract(payload, '//*[local-name()="statuscode"]'),
extract(payload, '//*[local-name()="statusmessage"]')
from source_table;
i can get first occurence or second occurence by specifying [1] or [2] but i need both the stauscodes to be displayed like below
10,john,1,one
10,john,2,two
any help here

Hope this is what you need: Just past this into an empty query window and execute. Adapt it for your needs:
This solution assumes, that the status codes are sorted (as in your example 1,2,...). If this could occur in random order, just ask again...
Short explanation: The CTE "NameAndCode" brings up the name and the statuscodes. The ROW_NUMBER-function give us the node's index. This index I use to fetch the right message.
One more hint: If you can change the XML's format, it would be better to make the message an attribut of statuscode or to have it as subnode...
DECLARE #xmlColumn XML='<root>
<name>john</name>
<status>
<statuscode>1</statuscode>
<statusmessage>one</statusmessage>
<statuscode>2</statuscode>
<statusmessage>two</statusmessage>
</status>
</root>';
WITH NameAndCode AS
(
SELECT #xmlColumn.value('(/root/name)[1]','varchar(max)') AS Name
,x.y.value('.','int') AS Statuscode
,x.y.query('..') XMLNode
,ROW_NUMBER() OVER(ORDER BY x.y.value('.','int')) AS StatusIndex
FROM #xmlColumn.nodes('/root/status/statuscode') AS x(y)
)
SELECT *
,XMLNode.value('(/status[1]/statusmessage[sql:column("StatusIndex")])[1]','varchar(max)')
FROM NameAndCode
