select (xpath('/chassis-inventory/chassis/serial-number/text()',
       data_xml,
       ARRAY[ARRAY['junos',
'http://xml.juniper.net/junos/9.6R4/junos-chassis']]
      )) from xml_test;

Can anyone suggest how I would go about getting the serial-number with xpath?



http://www.postgresql.org/docs/9.1/static/functions-xml.html#FUNCTIONS-XML-PROCESSING - see "mydefns".

This will work:

select xpath(
    '/junos:chassis-inventory/junos:chassis/junos:serial-number/text()',
    data_xml,
    ARRAY[ARRAY['junos', 'http://xml.juniper.net/junos/9.6R4/junos-chassis']]
)
from xml_test;



cheers, Filip
