Answer 1

這裏是代碼，只需幾行：

from bs4 import BeautifulSoup as b 
with open("sample.xml", "r") as f: # opening xml file 
    content = f.read() 
soup = b(content, "lxml") 
authornames = ([values.find("authorname").text.replace("\n", ' ') for values in soup.findAll("author")]) 
print authornames 

輸出：

[u' Anouk van der Hoorn ', u' Kamal M. Aden ', u' Peter Jan van Laar ']
