Hi Chris,
The GSA will stop processing and discard the feeds file if it
encounters a control characters, etc. I highly recommend that you run
a xml parser like xmllint on the feeds xml files to make sure that
there are no unwanted control characters. You can get the latest
version of the xmllint from here :
http://xmlsoft.org/ or may be
other sources as well.
Cheers,
Thiru
