Hi Tom,
Yes, that worked nicely thank you. But I'm getting another error :)
I loaded the example records provided in the data/cite directory (I'm
using Postgres 8.4 as db backend) and when doing this query:


I get this:

Traceback (most recent call last):
 File "/var/www/apps/pycsw/trunk/csw.py", line 40, in <module>
 File "/var/www/apps/pycsw/trunk/server/server.py", line 243, in dispatch

 File "/var/www/apps/pycsw/trunk/server/server.py", line 926, in getrecords
 File "/var/www/apps/pycsw/trunk/server/profiles/apiso/apiso.py",
line 375, in write_record
   codeSpace = CODESPACE).text = val

 File "apihelpers.pxi", line 1293, in lxml.etree._utf8
TypeError: Argument must be string or unicode.

val is None in apiso.py. If I check for val in line 371, the records
are returned nicely. (Of course I don't know the implications of this
