Hi all, I just wanted to share a (MariaDB) SQL report that I wrote for finding bib records with invalid XML characters: select biblionumber from biblio_metadata where metadata REGEXP '[^\\x{0009}\\x{000A}\\x{000D}\\x{0020}-\\x{D7FF}\\x{E000}-\\x{FFFD}\\x{1000 0}-\\x{10FFFF}]+'; Newer versions of Koha strip invalid character from the XML so that you can fix your records. I figure this report is very valuable when coupled with that functionality. In fact, I just advised a library today to use them together to fix up some bad data in their catalogue. -- On a related note, I've noticed that you can have a record with good bib XML but invalid item XML, and you won't notice until your record fails to be indexed. So I'm planning on writing a report for that too. I'm thinking it might be good to add these reports to core Koha, so that people can find and fix their own metadata problems. What do people think?
