Python package for extracting metadata, text, html and attachements from email messages.

Project description

emaildata is a python package for extracting content from email messages. It is a fork of the emailcontent package but adds from features.

emaildata features

emaildata extracts this types of contents from emails:

  • Extract metadata.
  • Extract text (plain text and html).
  • Extract attachments.

Extracting metadata

This feature was included from the metadata module of the emailcontent. This module was copied module, few methods of is MetaData class were removed, and the module was made more pylint friendly.

To extract metadata from an email message headers you create an instance of the MetaData class passing a message to the constructor. You can retrieve the metadata with the method to_dict. This can also be done using the method set_message:

import email
from emaildata.metadata import MetaData

message = email.message_from_file(open('message.eml'))
extractor = MetaData(message)
data = extractor.to_dict()
print data.keys()

message2 = email.message_from_file(open('message2.eml'))
extractor.set_message(message2)
data2 = extractor.to_dict()

Extracting text

The class Text in the text module have static methods for extracting text and html from messages:

import email
from emaildata.text import Text

message = email.message_from_file(open('message.eml'))
text = Text.text(message)
html = Text.html(message)

Extracting attachments

The method extract in the Attachment class returns an iterator with the decoded contents of the attachments of a message:

import email
from emaildata.attachment import Attachment

message = email.message_from_file(open('message.eml'))
for content, filename, mimetype, message in Attachment.extract(message):
    print filename
    with open(filename, 'w') as stream:
        stream.write(content)
    # If message is not None then it is an instance of email.message.Message
    if message:
        print "The file {0} is a message with attachments.".format(filename)

By default this method only iterates by the attachments with a filename. To retrieve all attachments you have to pass False as the second parameter (only_with_filename):

import email
import mimetypes
import uuid
from emaildata.attachment import Attachment

message = email.message_from_file(open('message.eml'))
for content, filename, mimetype, message in Attachment.extract(message, False):
    if not filename:
        filename = str(uuid.uuid1()) + (mimetypes.guess_extension(mimetype) or '.txt')
    print filename
    with open(filename, 'w') as stream:
        stream.write(content)
    # If message is not None then it is an instance of email.message.Message
    if message:
        print "The file {0} is a message with attachments.".format(filename)
