Answer 1

您可以将lxml与xpath一起用于教程，请参阅http://lxml.de/tutorial.html

from lxml import etree
# Read the xml file.
root = etree.parse("movies.xml")
# get the movie element with the title test Room
elems = root.xpath("//movie[title/text()='Room']")
# for the child elments print the data recursing through other children
def printitems (elems):
    for i in elems:
        print("%s - %s" % (i.tag, i.text))
        printitems(i)

printitems (elems[0])

给出

title - Room
formattype - video
genre - Drama
released - 
   2015

rate - 

rottentomatoes - 94%
imbd - 8.2
