Since you're using perl I think you mean XML::Simple which is a
DOM-parser. You also mentioned LibXML and are considering SAX-parsing so
I assume you've only used DOM-parsing then? How about using an XML
reader, kind of like SAX but a whole lot cleaner and easier - something
like:

use XML::LibXML::Reader;

my $reader = XML::LibXML::Reader->new(location => $filename_or_uri);
while ( $reader->read ) {
    next unless $reader->name eq 'record' &&
                $reader->nodeType eq XML_READER_TYPE_ELEMENT;
    my $dom = XML::LibXML->load_xml( string => $reader->readOuterXml );
    ...do something with the record element's dom-tree...
}
