How to assign an xpath query result to a variable

Question

I have a problem that I'm having trouble solving. I need to conditionally run a query based on the results of another query. Both are XPATH queries using extract. I can't seem to get it work as an IF...THEN; so I tried to assign a variable to the value of the query - lots of errors in SQL-Plus.
Here is a capsule of the queries:
This one validates the value of a state field from a table of the abbreviations. It works.
select 'Valid' from states where state =
(select extract(msg, '//RateRequest/*/SurveyAddress/StateCounty/text()').getStringVal()
from omnitest where mssgid = '300')
This one will check to see if the form is for a US address and is the one that needs to be conditional this doesn't work and I just left the If..Then statements in there for illustration. The query works fine by itself.
IF (select extract(msg, '//RateRequest/*/SurveyAddress/Country/text()').getStringVal()
from omnitest where mssgid = '300') = 'US' THEN
any help would be greatly appreciated.

Aanchal,
You said:
nothing happens and niether any error comesVery funny :-) Of-course no error comes -- because you "swallow" and ignore it in your code:
catch (SQLException sqlex) { }D'OH! (As Homer Simpson would say -- while slapping himself on the forehead!)
Try this instead:
catch (SQLException sqlex) {
  sqlex.printStackTrace();
}Good Luck,
Avi.
