under every "tecajnica" from witch I want to get "datum" as date I have more data,
first "tecaj" from witch I want to get "sifra" and under "tecaj" first I have "nakupni" from witch I want to get value of "nakupni" and second I have "prodajni" from witch I want to get value of "prodajni".
So the data I want would look like this:
For every "datum" I want "sifra", "nakupni" and "prodajni"
If I have in my xml file only one "datum" for "tecajnica" this is not a problem, I get this with this query:
SELECT     
extractValue(Value(d), 'tecajnica/.@datum','xmlns="http://www.bsi.si"') datum,
extractValue(VALUE(p), 'tecaj/.@sifra','xmlns="http://www.bsi.si"')     sval,
extractValue(VALUE(p), 'tecaj/nakupni','xmlns="http://www.bsi.si"') nakupni,
extractValue(VALUE(p), 'tecaj/prodajni','xmlns="http://www.bsi.si"') prodajni     
FROM     
Xml_tab x,
TABLE(XMLSequence(extract(x.xml, '/TecKomBS/tecajnica','xmlns="http://www.bsi.si"'))) d,
TABLE(XMLSequence(extract(x.xml, '/TecKomBS/tecajnica/*','xmlns="http://www.bsi.si"'))) p
but if I have xml file like example on top (with more dates), I get mix of all data in the xml file. So I get alot of wrong data!
I have tried some examples with Xqery but I gues I am doing something wrong.
Can you pleeease help me ?
Thanks for your time

Answer 1

I have tried also this, but I get error that doesn't mean nothing:
select xmlquery('for $i in $d/TecKomBS/Tecajnica where $i/.@datum eq
"2006-01-26" return $d/TecKomBS/Tecajnica/.@datum'
passing t.XML as "d" returning content)
from Xml_tab t
I get this:
SQL> /
passing t.XML as "d" returning content)
ERROR at line 2:
ORA-00907: missing right parenthesis
Can you help me please ?
