Pythonを使用してメールをメールトレイルから分離する

Question

私は電子メール関連のPoCでPythonを使用しています。システムはメールトレイルを含むメールを受信します。個々のメールをメールトレイルから分離して処理したかったのです。問題は、私はそれを行うための正しいコードやライブラリを取得していないです。誰でも助けてください。

------順列をたくさんした後----- 編集、私は、コードを次のようになってきました。

startMsgPatter= 
re.compile((\W*ORIGINAL\s*MESSAGE|\W*FROM\s*:|\W*ON.*WROTE\s*:)") 
def sperateEmails(callDesc): 
    itr = startMsgPatter.finditer(callDesc) 
    blockStart = 0 
    emails = [] 

    while True: 
     m = next(itr,None) 
     if not m: 
      break 
     blockEnd = m.start() 
     if blockStart >= blockEnd: 
      continue 
     emailPart = callDesc[blockStart:blockEnd] 
     emails.append(emailPart) 
     blockStart = blockEnd 
     emails.append(callDesc[blockStart:len(callDesc)]) 
    return emails 

私は動作していますが、メールの開始と終了を示すパターンを見つけて更新する必要があります。私のように、このメールトレイルは特定のパターンに従うべきです。誰もこのパターンの大部分を考慮してコードを書いていますか？それを共有してください。

Answer 1

あなたが機能分割を（使用することができます）

例：

"first mail separator second mail".split(" separator ") 

はoutpoutます：

を[ "最初のメール"、 "第二のメール"]

あなたはどのセパ使用するrator。セパレータは結果から削除されますが、必要に応じて後で再適用することができます。すべてのメッセージが文字列

"---------------ORIGINAL MESSAGE------------------" 

または

"FROM" 

で分離されているようなあなたの場合には

、私がこのような第二に、最初の1とのあなた最初のスプリットことを示唆しているようです：

all = [] # Splitted messages will be stored here 
# mail_trail is the content of your mail trail 
sep = mail_trail.split("---------------ORIGINAL MESSAGE------------------") 
for msg in sep: 
    sep2 = msg.split("FROM") 
    if len(sep2) == 2: # has splitted 
     sep2[1] = "FROM" + sep2[1] # reappend the FROM since you need it 
    all.extend(sep2) # Add the messages in the array 

これは適切なトラックに置く必要があります。
