Hi all

I have a field with XML data in a database. A tag occurs several times in XML. How can I read this out so that each element is displayed in a column? With extractvalue i don't get any further because the element occurs several times.

XML:
<Cdtr>

<Nm>Mustername</Nm>

<PstlAdr>

<AdrLine>Testadresse</AdrLine>

<AdrLine>1234 Ort</AdrLine>

</PstlAdr>

</Cdtr>

Desired result:
Nm | AdrLine1 | AdrLine 2
Mustername | Testadresse |1234 Ort

Thanks for your reply!

Welcome to the forum.
Please read the OraFAQ Forum Guide and How to use [code] tags and make your code easier to read.
Make sure that lines of code do not exceed 100 characters when you format.

Many thanks for your fast reply! In my XML is a Namespace. How does your query work with a namespace? Here the original XML:

XMLTABLE takes a first parameter XMLNAMESPACES.

sorry, i am not able to define the namespace correctly. How exactly does that have to be done?

Well, I don't know, I admit I have never use XMLTABLE with namespaces.
This works:
SQL> with
  2  data as (
  3    select '<?xml version="1.0" encoding="UTF-8"?>
  4            <Document>
  5              <FIToFICstmrCdtTrf>

  7                  <Cdtr>
  8                    <Nm>Mustername</Nm>
  9                      <PstlAdr>
 10                        <AdrLine>Testadresse</AdrLine>
 11                        <AdrLine>1234 Ort</AdrLine>

 18           )
 19   select x.nm,
 20          max(decode(y.pos, 1, y.addr)) Addr1,
 21          max(decode(y.pos, 2, y.addr)) Addr2
 22   from data,
 23        xmltable('/Document/FIToFICstmrCdtTrf/CdtTrfTxInf/Cdtr' passing xmltype(data)
 24                 columns
 25                   nm    varchar2(20) path '/Cdtr/Nm',
 26                   addrs xmltype      path '/Cdtr/PstlAdr/AdrLine'

 36   group by x.nm
 37  /

no rows selected
Maybe because I have no access to namespace?
