NAME
Mail::MboxParser::Mail::Body - rudimentary mail-body object
SYNOPSIS
use Mail::MboxParser;
[...]
# $msg is a Mail::MboxParser::Mail
my $body = $msg->body(0);
# or preferably
my $body = $msg->body($msg->find_body);
for my $line ($body->signature) { print $line, "\n" }
for my $url ($body->extract_urls(unique => 1)) {
print $url->{url}, "\n";
print $url->{context}, "\n";
}
DESCRIPTION
This class represents the body of an email-message. Since emails can have multiple MIME-parts and each of these parts has a body it is not always easy to say which part actually holds the text of the message (if there is any at all). Mail::MboxParser::Mail::find_body will help and suggest a part.
METHODS
- as_string
-
Returns the textual representation of the body as one string. Decoding takes place when the mailbox has been opened using the decode => 'BODY' | 'ALL' option.
- as_lines
-
Sames as as_string() just that you get an array of lines.
- signature
-
Returns the signature of a message as an array of lines. Trailing newlines are already removed.
$body->error returns a string if no signature has been found.
- extract_urls
- extract_urls (unique => 1)
-
Returns an array of hash-refs. Each hash-ref has two fields: 'url' and 'context' where context is the line in which the 'url' appeared.
When calling it like $mail->extract_urls(unique => 1), duplicate URLs will be filtered out regardless of the 'context'. That's useful if you just want a list of all URLs that can be found in your mails.
$body->error() will return a string if no URLs could be found within the body.
- quotes
-
Returns a hash-ref of array-refs where the hash-keys are the several levels of quotation. Each array-element contains the paragraphs of this quotation-level as one string. Example:
my $quotes = $msg->body($msg->find_body)->quotes; print $quotes->{1}->[0], "\n"; print $quotes->{0}->[0], "\n";This should print the first paragraph of the mail-body that has been quoted once and below that the paragraph that supposedly is the reply to this paragraph. Perhaps thus:
> I had been trying to work with the CGI module > but I didn't yet fully understand it. Ah, it is tricky. Have you read the CGI-FAQ that comes with the module?Mark that empty lines will not be ignored and are part of the lines contained in the array of $quotes->{0}.
So below is a little code-snippet that should, in most cases, restore the first 5 paragraphs (containing quote-level 0 and 1) of an email:
for (0 .. 5) { print $quotes->{0}->[$_]; print $quotes->{1}->[$_]; }Since quotes() considers an empty line between two quotes paragraphs as a paragraph in $quotes->{0}, the paragraphs with one quote and those with zero are balanced. That means:
scalar @{$quotes->{0}} - DIFF == scalar @{$quotes->{1}} where DIFF is element of {-1, 0, 1}.
Unfortunately, quotes() can up to now only deal with '>' as quotation-marks.
