If I have a XML like this
<?xml version="1.0" encoding="UTF-8"?>
<Errors>
<Error code="CLIN102" validFrom="1980-02-23"/>
<Error code="CLIN103" validFrom="1980-02-23" validTo="2012-01-01"/>
</Errors>
can I write a query that will output the columns names and values like this?
code;validFrom;validTo
------------------------------
CLIN102;1980-02-23;
CLIN103;1980-02-23;2012-01-01
Thank you

You should be able to do it with some xpath expressions. It probably
won't be fast or pretty. Consider using PL/Python, PL/perl, PL/Java, or
something like that to do the processing and return the resultset.
