Selecting data from XML

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
