?????? 一款名為 Beautiful Soup 的常用配套工具幫助 Python 程序理解 Web 站點中包含的臟亂“基本是 HTML” 內(nèi)容。是用Python寫的一個HTML/XML的解析器，它可以很好的處理不規(guī)范標(biāo)記并生成剖析樹(parse tree)。

使用 Beautiful Soup 從無序的內(nèi)容中生成整齊的數(shù)據(jù)

from glob import glob from BeautifulSoup import BeautifulSoupdef process():print "!MOVIE,DIRECTOR,KEY_GRIP,THE_MOOSE"for fname in glob('result_*'):# Put that sloppy HTML into the soupsoup = BeautifulSoup(open(fname))# Try to find the fields we want, but default to unknown valuestry:movie = soup.findAll('span', {'class':'movie_title'})[1].contents[0]except IndexError:fname = "UNKNOWN"try:director = soup.findAll('div', {'class':'director'})[1].contents[0]except IndexError:lname = "UNKNOWN"try:# Maybe multiple grips listed, key one should be in theregrips = soup.findAll('p', {'id':'grip'})[0]grips = " ".join(grips.split()) # Normalize extra spacesexcept IndexError:title = "UNKNOWN"try:# Hide some stuff in the HTML <meta> tagsmoose = soup.findAll('meta', {'name':'shibboleth'})[0]['content']except IndexError:moose = "UNKNOWN"print '"%s","%s","%s","%s"' % (movie, director, grips, moose)
