用美麗的湯寫入xml

Question

這可能是一個真正愚蠢的問題，但我還沒有找到答案。 一旦我根據需要修改xml樹，我如何將它寫回到文件？

代碼：

workbook = open("C:\\Users\\rabdel.WINCMPT\\Documents\\Retail Footwear.twb") 
soup = BeautifulSoup(workbook) 

for dashboard in soup.findAll("dashboard"): 
    print dashboard["name"] 
    if dashboard["name"] == "S1": 
     dashboard.extract() 

for window in soup.findAll("window"): 
    print "class:",window["class"] 
    if "name" in [x[0] for x in window.attrs]: 
     print "name:",window["name"] 
     if window["name"] == "S1": 
      window.extract() 

Answer 1

最簡單的方法，得到輸出作爲一個字符串並寫入文件：

f = open(workbook.name, "w") 
f.write(soup.prettify()) 
f.close() 

Answer 2

從文檔：you can turn a Beautiful Soup document (or any subset of it) into a string with the str function, or the prettify or renderContents methods. You can also use the unicode function to get the whole document as a Unicode string.

然後只寫字符串到文件中，就像任何其他字符串。
