Mike, I tried both of your suggested fixes (changing Name to LocalName, and running the updated patch), but no luck. I still get no error messages in the error log, but the program silently fails to print a report. If I manually remove the "mx:" namespace strings from all the tags, I can process the files with no problem. (So one quick fix would be to simply run these records through a quick search and replace routine.)
Regarding the problem name authority files. They're all available on the web from OCLC's experimental name authority service, at http://alcme.oclc.org/eprintsUK/index.html You enter an author name (I entered "Robert Benchley"). Then I clicked on the first link at http://errol.oclc.org/laf/n50-7168.html Finally, I clicked on the second link ("XML Record") to get this link: http://errol.oclc.org/laf/n50-7168.MarcXML All of these have the "mx:" namespace notation in their tags. - Chris
