Oracle 10.2.0.4.0 query on partial xpath - sql

Question

I need to change the below query to be able to query any kind of tender item.
/Basket/CardTenderItem/Description
/Basket/CashTenderItem/Description
So
/Basket/WildcardTenderItem/Description
I have looked at various examples on but cannot them to bring back any results when running (happily admit to user error if can get working!)
SELECT
RETURN_ID
,SALE_ID,
,extractValue(xmltype(RETURNxml),'/Basket/CashTenderItem/NetValue')
,extractValue(xmltype(RETURNxml),'/Basket/CashTenderItem/Description')
FROM SPR361
WHERE return_id = '9999.0303|20170327224954|2063'

Answer 1

If you only want to match anything the ends with TenderItem, but doesn't have anything after that, you could be specific with substring checks:
SELECT
RETURN_ID
,SALE_ID
,extractValue(xmltype(RETURNxml),
'/Basket/*[substring(name(), string-length(name()) - 9) = "TenderItem"]/NetValue')
,extractValue(xmltype(RETURNxml),
'/Basket/*[substring(name(), string-length(name()) - 9) = "TenderItem"]/Description')
FROM SPR361
WHERE return_id = '9999.0303|20170327224954|2063'
If you never have any nodes with anything after that fixed string then #Shnugo's contains approach is easier, and in Oracle would be very similar:
...
,extractValue(xmltype(RETURNxml),
'/Basket/*[contains(name(), "TenderItem")]/NetValue')
,extractValue(xmltype(RETURNxml),
'/Basket/*[contains(name(), "TenderItem")]/Description')
I'm not sure there's any real difference between name() and local-name() here.
If a basket can have multiple child nodes (card and cash, or more than one of each) you could also switch to XMLTable syntax:
SELECT
s.RETURN_ID
,s.SALE_ID
,x.netvalue
,x.description
FROM SPR361 s
CROSS JOIN XMLTable(
'/Basket/*[contains(name(), "TenderItem")]'
PASSING XMLType(s.RETURNxml)
COLUMNS netvalue NUMBER PATH './NetValue'
, description VARCHAR(80) PATh './Description'
) x
WHERE s.return_id = '9999.0303|20170327224954|2063'
And it's overkill here maybe, but for more complicated tests you can use other XPath syntax, like:
CROSS JOIN XMLTable(
'for $i in /Basket/*
where contains($i/name(), "TenderItem") return $i'
PASSING XMLType(s.RETURNxml)
...

This is SQL-Server syntax and I cannot test, if this works with Oracle too, but I think it will. You can use XQuery function contains():
DECLARE #xml XML=
N'<root>
<abcTenderItem>test1</abcTenderItem>
<SomeOther>should not show up</SomeOther>
<xyzTenderItem>test2</xyzTenderItem>
</root>';
SELECT #xml.query(N'/root/*[contains(local-name(),"TenderItem")]')
only the elements with "TenderItem" in their names show up:
<abcTenderItem>test1</abcTenderItem>
<xyzTenderItem>test2</xyzTenderItem>
