Iterating over a message object tree is fairly easy with the Message.walk()
method. The email.Iterators module provides some useful higher level
iterations over message object trees.
-
| body_line_iterator( |
msg[, decode]) |
- This iterates over all the payloads in all the subparts of msg, returning the
string payloads line-by-line. It skips over all the subpart headers, and it skips over any
subpart with a payload that isn't a Python string. This is somewhat equivalent to reading
the flat text representation of the message from a file using readline(),
skipping over all the intervening headers.
Optional decode is passed through to Message.get_payload().
-
| typed_subpart_iterator( |
msg[, maintype[, subtype]]) |
- This iterates over all the subparts of msg, returning only those subparts
that match the MIME type specified by maintype and subtype.
Note that subtype is optional; if omitted, then subpart MIME type matching
is done only with the main type. maintype is optional too; it defaults to text.
Thus, by default typed_subpart_iterator() returns each
subpart that has a MIME type of text/*.
The following function has been added as a useful debugging tool. It should not be
considered part of the supported public interface for the package.
-
| _structure( |
msg[, fp[, level]]) |
- Prints an indented representation of the content types of the message object structure.
For example:
>>> msg = email.message_from_file(somefile)
>>> _structure(msg)
multipart/mixed
text/plain
text/plain
multipart/digest
message/rfc822
text/plain
message/rfc822
text/plain
message/rfc822
text/plain
message/rfc822
text/plain
message/rfc822
text/plain
text/plain
Optional fp is a file-like object to print the output to. It must be
suitable for Python's extended print statement. level is used internally.
