Simply use raise:

try:
    some_parsing_with_minidom(from_a_line)
except SAXParseException: # (1)
    # there are trouble in my file such as & instead of &
    # and other things which prevent correct parsing but
    # i don't know where and what cause my trouble
    print index_of_line, line
    raise #<- should be the one i intercept in (1) <- it is :-)
