How to not die

[BeHealthy]

I am using XML::RSS module to parse lots of RSS files in batch. However
if one of the RSS files has invalid format, then a die call is thrown
from the parser. Is there any way I can handle the die call, so that
the program can keep running by skipping the invalid RSS file?

Use a BLOCK-eval (not to be confused with STRING-eval):

eval {
# code that potentially dies
}
if ($@) {
print "Code died with message '$@'";
}

Wrap your code in a block eval() - not to be confused with a string eval().
eval() returns undef on failure, and you can check $@ for the message given
to die(). For instance:

# Not a complete program, obviously...
eval {
do_something();
} or {
warn $@ if $@;
}

Depending on do_something's return value, this might still execute the
or-branch. I'd rather write this as:

eval {
do_something();
1;
} or warn $@;
