[EP-tech] Antwort: Re: {Disarmed} International characters in advanced search fail for XML-Export

Dear Adam,

because Jens is out of the office for a few days, I jump in.

I take one of the records that is found by the saved search and where there is a German umlaut in the creator's name (Krüger, G):

bin/export zora eprint XMLforCMS2 95663

just exports fine, and we obtain the expected XML:

<?xml version="1.0" encoding="utf-8" ?>

If we open the saved search with the "offending" umlaut (by clicking the link in the "Name of search" column), the search is execute and yields a result list.
You can then export the results by choosing an export plugin from the drop down menu. All export plugins (including XMLforCMS2) do work this way.


In the last column of the saved search table there is a special button that calls cgi/saved_search by passing savedsearch_id as parameter.
This button and the saved_search cgi script (seem to) have been extended by EPrints Services for us.

Jens has opened a support case with Justin to check this script - we assume that the problem is somewhere generated in the line

print $saved_search->make_searchexp->perform_search->export( $format );

when a "virtual" dataset is passed to the export plugin and there is an umlaut in the originating query.

This problem not only happens with the XMLforCMS2 export - it happens with any export format that is passed to the extended saved_search CGI script.

Best regards,

Martin

What happens if you export the record on the command line?
