\modulesynopsis{Iterate over a message object tree.}
|
|
|
|
Iterating over a message object tree is fairly easy with the
|
|
\method{Message.walk()} method. The \module{email.Iterators} module
|
|
provides some useful higher level iterations over message object
|
|
trees.
|
|
|
|
\begin{funcdesc}{body_line_iterator}{msg}
|
|
This iterates over all the payloads in all the subparts of \var{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
|
|
\method{readline()}, skipping over all the intervening headers.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{typed_subpart_iterator}{msg\optional{,
|
|
maintype\optional{, subtype}}}
|
|
This iterates over all the subparts of \var{msg}, returning only those
|
|
subparts that match the MIME type specified by \var{maintype} and
|
|
\var{subtype}.
|
|
|
|
Note that \var{subtype} is optional; if omitted, then subpart MIME
|
|
type matching is done only with the main type. \var{maintype} is
|
|
optional too; it defaults to \mimetype{text}.
|
|
|
|
Thus, by default \function{typed_subpart_iterator()} returns each
|
|
subpart that has a MIME type of \mimetype{text/*}.
|
|
\end{funcdesc}
