Hello

I would like to read some values from XML code, I try to do some test sql query but not successfully.

The values what I need from xml are:
<currency>EUR</currency>
<amount>64.93</amount>



And there is a one example of xml:

 CREATE TABLE "XML_TAB" 
   (	"ID" NUMBER(10,0), 
	"FILENAME" VARCHAR2(100 BYTE), 
	"XML" "XMLTYPE"
   )

 Insert into XML_TAB (ID,FILENAME,XML) values ('1','2610748023_20120102.xml','<?xml version = ''1.0'' encoding = ''UTF-8'' standalone = ''no''?><?xml-stylesheet type="text/xsl" href="http://moja.tatrabanka.sk/ibanking/xsl/ikey-print.xsl"?>

Post what you already tried.
There are many examples in this forum to "extractvalue" from XML. (clue: this is a clue)

I tried to select these values from this query but not successfully:

select t2.X1_VALUE2,t.id, t.filename
from xml_tab t, 
     XMLTABLE(XMLNAMESPACES(default 'http://www.tatrabanka.sk/tb_types'),
                   'for $i in /*
                      return <dtp name="{$i/name()}">
                              {
                                for $j in $i/*
                                return $j
                              }
                             </dtp>'
                   passing t.xml
                   columns
X1_VALUE2 varchar2(50) PATH '/dtp/statement/movements/movement/code[@name]/text/text()'
  ) t2

There are several "amount" and "currency" nodes, how can we (and Oracle) know which one you want?

The values "amount" and "currency" nodes should be selected from all appearances.

I don't understand, this is not what you first posted.
What is the result you want from the data you gave?
What is the rule to select this result?

I first posted just about values:

<currency>EUR</currency>
<amount>64.93</amount>


And if somebody give me a right select how to do this then I use this one to another one values (as I wrote last).


Lets just talk about "amount" and "currency" nodes.

Simply select all values from "amount" and "currency" nodes.

The following are various different syntaxes for doing what you asked. The first is an older syntax. The second is a newer syntax and is what I recommend in this situation. The third, fourth, and fifth are similar to what you seem to be trying to do. I believe the third, fourth, and fifth syntaxes are intended for more complex things where there is more nesting of values and are unnecessarily overcomplicated for what you are trying to do here. I posted them only so you could see the difference and test them if you like.
