mime::parser::results5.18
MIME::Parser::Results(3) User Contributed Perl Documentation MIME::Parser::Results(3)NAME
MIME::Parser::Results - results of the last entity parsed
SYNOPSIS
Before reading further, you should see MIME::Parser to make sure that you understand where this module fits into the grand scheme of
things. Go on, do it now. I'll wait.
Ready? Ok...
### Do parse, get results:
my $entity = eval { $parser->parse(*STDIN); };
my $results = $parser->results;
### Get all messages logged:
@msgs = $results->msgs;
### Get messages of specific types (also tests if there were problems):
$had_errors = $results->errors;
$had_warnings = $results->warnings;
### Get outermost header:
$top_head = $results->top_head;
DESCRIPTION
Results from the last MIME::Parser parse.
PUBLIC INTERFACE
new Constructor.
msgs
Instance method. Return all messages that we logged, in order. Every message is a string beginning with its type followed by ": ";
the current types are "debug", "warning", and "error".
errors
Instance method. Return all error messages that we logged, in order. A convenience front-end onto msgs().
warnings
Instance method. Return all warning messages that we logged, in order. A convenience front-end onto msgs().
top_head
Instance method. Return the topmost header, if we were able to read it. This may be useful if the parse fails.
