Oracle XMLtable giving cross joined data - sql

Question

I have written a Oracle XML sql and it is giving output like below. I have given the whole code below from creating table to sql below for your quick help.
output: (WRONG)
ID, NAME
1 name1
1 name2
2 name1
2 name2
Want to make output like below (Required Output):
ID, NAME
1 name1
2 name2
Code:
CREATE TABLE XML_TBL
( "INSTANCE_DETAIL_XML" "SYS"."XMLTYPE"
);
SET DEFINE OFF;
Insert into XML_TBL (INSTANCE_DETAIL_XML) values ('<?xml version="1.0" encoding="UTF-8" standalone=''yes''?>
<driXML>
<sDet>
<cols>
<col>
<id>1</id>
<name>name1</name>
</col>
<col>
<id>2</id>
<name>name2</name>
</col>
</cols>
</sDet>
</driXML>
');
I tried the below sql, you may modify it or create a new one using it:
Select XT_ID.id
, XT_NAME.name
FROM xml_tbl XT
join XMLTABLE
('/driXML' PASSING XT.INSTANCE_DETAIL_XML COLUMNS
id_XML XMLType PATH 'sDet/cols/col/id'
, name_XML XMLType PATH 'sDet/cols/col/name'
) RI_XML on 1=1
join XMLTABLE('/id' PASSING RI_XML.id_XML COLUMNS ID number PATH '.') XT_ID on 1=1
join XMLTABLE('/name' PASSING RI_XML.name_XML COLUMNS NAME varchar2(50) PATH '.') XT_NAME on 1=1
;

Answer 1

You can just directly extract the id and name in the first XMLTABLE and if you descend through the hierarchy so that the path is '/driXML/sDet/cols/col' then each row from the XMLTYPE will be one col element and the id and name will correlate to that.
Oracle Setup:
CREATE TABLE XML_TBL( INSTANCE_DETAIL_XML ) AS
SELECT XMLTYPE( '<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<driXML>
<sDet>
<cols>
<col>
<id>1</id>
<name>name1</name>
</col>
<col>
<id>2</id>
<name>name2</name>
</col>
</cols>
</sDet>
</driXML>' ) FROM DUAL;
Query:
SELECT id,
name
FROM xml_tbl XT
CROSS JOIN XMLTABLE(
'/driXML/sDet/cols/col'
PASSING XT.INSTANCE_DETAIL_XML
COLUMNS
id NUMBER PATH 'id',
name VARCHAR2(50) PATH 'name'
);
Output:
ID | NAME
-: | :----
1 | name1
2 | name2
