hi all,
I've inserted xml file :

<?xml version="1.0"?>
<document xmlns:s1="urn:myorg/s1" xmlns="urn:myorg"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<id num="111-222-333-4444"/>
<title>zzzzzz</title>
......................

to a table:

CREATE TABLE "temp".tempxml
(
record xml
)

I can get it using:
select * from temp.tempxml

but, I can't get any values using xpath. ex:

select (xpath('/document/title/text()', record ))[1] from temp.tempxml

am I doing it right?

thanks.
