Description Mark Jordan 2009-03-11 14:05:31 PDT

Harvesting MODS archives using harvest.php produces the following error:

"PHP Warning:  Invalid argument supplied for foreach() in /mnt/u0/var/www/html/chodarr-test/lib/pkp/classes/xml/XMLNode.inc.php on line 138"

Records are added but they are empty (more specifically, nothing is showing up in the browse list but a link to view record, and the record itself is empty.

The error message does not appear when harvesting via the web interface, but the result is the same -- empty records.

Harvesting DC and ETD-MS archives works as expected. The MODS archives (they are actually static repositories at http://harvesters.sfu.ca/static_repositories/) that are producing the error/not populating records posed no problems in Harvester 2.0.1.0 Harvester. The DC and ETD-MS archives I tested were not static repositories.
