For example, my clob contains xml content as shown below
<?xml version="1.0"?>
<content>
<foo>bar</foo>
<bar>foo</bar>
</content>
When i print it using loop, struct of content is not well-formed.
Use XMLSerialize function:
with test_data as (
select
'<?xml version="1.0"?><content>
<foo>bar</foo><bar>foo</bar></content>' as x_data
from dual
)
select
xmlserialize(document xmltype(x_data) as clob indent size = 2) x_text
from test_data

Can you please help me out to fix the following?
I only required a person_number once eg. 1000142 but I'm getting 10001421000142 like this.
Because the values I have in XML cell have repeating number, so I only want to extract one unique person number.
select xmltype('<?xml version="1.0"?>
<ROWSET>
<ROW0> <PERSON_NUMBER>1000142</PERSON_NUMBER> <LOAN_1>25000</LOAN_1> <LOAN_2>26000</LOAN_2>
</ROW0>
<ROW0> <PERSON_NUMBER>1000142</PERSON_NUMBER> </ROW0> <LOAN_1>25000</LOAN_1> <LOAN_2>26000</LOAN_2>
</ROW0>
</ROWSET>').extract( '//PERSON_NUMBER/text()' ).getstringval() p#
from dual;
Based on your initial version of the question (where the XML is a valid with a single root element rather than a forest of elements), you can use:
select xmltype(
'<?xml version="1.0"?>
<ROWSET>
<ROW>
<PERSON_NUMBER>1000142</PERSON_NUMBER>
<PERSON_NUMBER>1000142</PERSON_NUMBER>
<LOAN_1>25000</LOAN_1>
<LOAN_2>26000</LOAN_2>
</ROW>
</ROWSET>').extract( '//PERSON_NUMBER[1]/text()' ) .getstringval() p#
from dual;
Which outputs:
P#
1000142

I have created a query to pull data from XML column of table however I am having issue when XML has list of data i.e.
Cola Brand has multiple code inside
See My query
select extract(cola_info, '/ns2:cola/coke/bottleCode', 'xmlns:ns2="http://myColaStaticInfo.com"') as op;
Output is something like
I would like to have highlighted content one after another and not together in one column.
Any idea!!!
MY XML look like this
<?xml version="1.0" encoding="ISO-8859-15" standalone="yes"?>
<ns2:cola xmlns:ns2="http://myColaStaticInfo.com">
<coke>
<code>Bottle_2829</code>
<label>Mirinda</label>
</coke>
<coke>
<code>Bottle_2830</code>
<label>Mirinda</label>
</coke>
<coke>
<code>Bottle_2831</code>
<label>Mirinda</label>
</coke>
</ns2:cola>
XMLTable is probably your best choice for this. Especially since extract has been deprecated.
with example_data as (select xmltype('<?xml version="1.0" encoding="ISO-8859-15" standalone="yes"?>
<ns2:cola xmlns:ns2="http://myColaStaticInfo.com">
<coke>
<code>Bottle_2829</code>
<label>Mirinda</label>
</coke>
<coke>
<code>Bottle_2830</code>
<label>Mirinda</label>
</coke>
<coke>
<code>Bottle_2831</code>
<label>Mirinda</label>
</coke>
</ns2:cola>') as xml from dual)
-- query
select bottle_coke
from example_data e
cross join XMLTABLE(XMLNAMESPACES('http://myColaStaticInfo.com' as "ns2"),
'/ns2:cola/coke'
PASSING e.xml
COLUMNS
bottle_coke XMLTYPE PATH 'code'
) xt;
Output:
<code>Bottle_2829</code>
<code>Bottle_2830</code>
<code>Bottle_2831</code>
I am trying to update an element which is inside a clob column in oracle DB.
First challenge I am facing is that my clob xml has 2 namespaces and I am not able to get that working .
<?xml version="1.0"?>
<esbmsg:EsbMessage xmlns:esbmsg="http://www.test.com/esb/message/1.0">
<esbmsg:Body>
<Transaction xmlns="http://test.com">
<test-element>
<finalElement>false</finalElement>
</test-elemen>
</Transaction>
</esbmsg:Body>
</esbmsg:EsbMessage>
select x.* from cc_messagehistory y
cross join xmltable(
xmlnamespaces('http://www.test.com/esb/message/1.0' as "esbmsg",
'http://test.com ' ),
'/esbmsg:EsbMessage'
passing xmltype.createxml(y.payload)
factext varchar2(10) path '/esbmsg:EsbMessage/esbmsg:Body/Transaction/test-element/finalElement'
) x;
ORA-19102: XQuery string literal expected
19102. 00000 - "XQuery string literal expected"
*Cause: The string literal containing the XQuery expression was missing.
*Action: Specify the XQuery expression as a string literal. Error at Line: 64 Column: 99
The immediate cause of the ORA-01902 is that you missed the default keyword:
xmlnamespaces('http://www.test.com/esb/message/1.0' as "esbmsg",
default 'http://test.com'),
I've removed the extra space at the end of the URI, which would cause problems later. But you are also missing the columns keyword, and you can simplify the conversion of the CLOB value to an XMLType.
Putting that together, and with a CTE to supply your (corrected) sample XML:
-- CTE for sample data
with cc_messagehistory(payload) as (
select to_clob('<?xml version="1.0"?>
<esbmsg:EsbMessage xmlns:esbmsg="http://www.test.com/esb/message/1.0">
<esbmsg:Body>
<Transaction xmlns="http://test.com">
<test-element>
<finalElement>false</finalElement>
</test-element>
</Transaction>
</esbmsg:Body>
</esbmsg:EsbMessage>') from dual
)
-- actual query
select x.*
from cc_messagehistory y
cross join xmltable (
xmlnamespaces (
'http://www.test.com/esb/message/1.0' as "esbmsg",
default 'http://test.com'
),
'/esbmsg:EsbMessage'
passing xmltype(y.payload)
columns factext varchar2(10)
path '/esbmsg:EsbMessage/esbmsg:Body/Transaction/test-element/finalElement'
) x;
FACTEXT
----------
false
For the update you could do something like:
update cc_messagehistory y
set payload = XMLSerialize(document
XMLQuery('declare default element namespace "http://test.com"; (: :)
declare namespace esbmsg="http://www.test.com/esb/message/1.0"; (: :)
copy $i := $xml modify (
for $j in $i//esbmsg:EsbMessage/esbmsg:Body/Transaction/test-element/finalElement
return replace value of node $j with $new
)
return $i'
passing xmltype(y.payload) as "xml",
'true' AS "new"
returning content
)
indent size=2
)
where xmlexists('declare default element namespace "http://test.com"; (: :)
declare namespace esbmsg="http://www.test.com/esb/message/1.0"; (: :)
$xml//esbmsg:EsbMessage/esbmsg:Body/Transaction/test-element/finalElement[text()="false"]'
passing xmltype(y.payload) as "xml");
which transforms that source CLOB into:
<?xml version="1.0"?>
<esbmsg:EsbMessage xmlns:esbmsg="http://www.test.com/esb/message/1.0">
<esbmsg:Body>
<Transaction xmlns="http://test.com">
<test-element>
<finalElement>true</finalElement>
</test-element>
</Transaction>
</esbmsg:Body>
</esbmsg:EsbMessage>

please help me
Your XML document has a namespace, so you either need to wildcard the nodes in your XMLTable call, or - preferably - supply the same namespace information and prefixes:
-- CTE for sample data
with tb_test (xml1) as (select '<?xml version="1.0" encoding="UTF-8"?>
<ns0:testata xmlns:ns0="http://siete">
<ns0:product>
<ns0:YEAR>2019</ns0:YEAR>
<ns0:PERIOD>1</ns0:PERIOD>
</ns0:product>
<ns0:product>
<ns0:YEAR>2019</ns0:YEAR>
<ns0:PERIOD>2</ns0:PERIOD>
</ns0:product>
</ns0:testata>' from dual
)
-- actual query
select x.year
from tb_test t
cross join xmltable(
xmlnamespaces('http://siete' as "ns0"),
'/ns0:testata/ns0:product'
passing xmltype(t.xml1)
columns year number path 'ns0:YEAR'
) x;
YEAR

2019
2019
I have a column that gives me lines like this:
<?xml version="1.0" encoding="UTF-8"?>
<xSettings>
<systemPropertyName>BLALBLA</systemPropertyName>
<minimumAmount>198.00</minimumAmount>
<closingAmount>198.00</closingAmount>
<useThisSetting>true</useThisSetting>
<SystemStep dayAfterPrevious="0">
<System SystemService="1" minimumAmount="450.00" />
</SystemStep>
<SystemStep dayAfterPrevious="8">
<message />
</SystemStep>
<SystemStep dayAfterPrevious="3">
<block />
</SystemStep>
<SystemStep dayAfterPrevious="1">
<message />
</SystemStep>
<SystemStep dayAfterPrevious="7">
<message />
</SystemStep>
</xSettings>
All numbers in it are variable and the BLA BLA is variable too. What I want is a select that only gives me
<minimumAmount>198.00</minimumAmount>
though this would be eve better:
198.00
basically, I can't figure out how to use regexp_substr to find a specific string , then return a number just after that may be from 1 to 4 digits and has two decimals after.
Do not use regular expressions to parse XML data - use a proper XML parser:
SELECT x.minimumAmount
FROM your_table t,
XMLTable(
'/xSettings',
PASSING XMLType( t.your_column )
COLUMNS minimumAmount NUMBER(5,2) PATH './minimumAmount'
) x
Or
SELECT TO_NUMBER(
EXTRACTVALUE( XMLType( your_column ), '/xSettings/minimumAmount' )
) AS minimumAmount
FROM your_table
XML data should not be queried using regular expressions, but here:
select
regexp_substr(col, '<minimumAmount>(.*)</minimumAmount>',1,1,null,1) minimum_amount
from your_table;
One other way is to use regexp_replace like this:
select
regexp_replace(col, '.*<minimumAmount>(.*)</minimumAmount>.*','\1') minimum_amount
from your_table;
