应该很明显我需要提取哪个链接。

Answer 1

@OP，如果你的邮箱格式总是一样的，

f=open("emailfile")
for line in f:
    if "confirm your submission" in line:
        print f.next().strip()        
f.close()

Answer 2

如果你要处理带有超链接的HTML邮件，可以使用HTMLParse这个库，这样会更简单快捷。

import HTMLParser
class parseLinks(HTMLParser.HTMLParser):
    def handle_starttag(self, tag, attrs):
        if tag == 'a':
            for name, value in attrs:
                if name == 'href':
                    print value
                    print self.get_starttag_text()

someHtmlContainingLinks = ""
linkParser = parseLinks()
linkParser.feed(someHtmlContainingLinks)

这个解决方案只有在源内容不是HTML的时候才有效。

def extractURL(self,fileName):

    wordsInLine = []
    tempWord = []
    urlList = []

    #open up the file containing the email
    file = open(fileName)
    for line in file:
        #create a list that contains each word in each line
        wordsInLine = line.split(' ')
        #For each word try to split it with :
        for word in wordsInLine:
            tempWord = word.split(":")
            #Check to see if the word is a URL
            if len(tempWord) == 2:
                if tempWord[0] == "http" or tempWord[0] == "https":
                    urlList.append(word)

    file.close()

    return urlList
