Você pode me ajudar de como resolver alguma coisa aqui:
Malformed response: mismatched tag at line 23, column 2, byte 1413 at /usr/lib64/perl5/vendor_perl/XML/Parser.pm line 187. . The most common reason for malformed responses is illegal bytes in UTF-8 streams (e.g. the inclusion of Latin1 characters with codes>127 without creating proper UTF-8 mutli-byte sequences). You might find the utf8conditioner, found on the OAI tools page helpful for debugging.
My file looks like this
