Python：使用基于事件驱动的SAX解析XML(3)

class MovieHandler( xml.sax.ContentHandler ):
  def __init__(self):
      self.CurrentData = ""
      self.type = ""
      self.format = ""
      self.year = ""
      self.rating = ""
      self.stars = ""
      self.description = ""

# 元素开始事件处理
  def startElement(self, tag, attributes):
      self.CurrentData = tag
      if tag == "movie":
        print "*****Movie*****"
        title = attributes["title"]
        print "Title:", title

# 元素结束事件处理
  def endElement(self, tag):
      if self.CurrentData == "type":
        print "Type:", self.type
      elif self.CurrentData == "format":
        print "Format:", self.format
      elif self.CurrentData == "year":
        print "Year:", self.year
      elif self.CurrentData == "rating":
        print "Rating:", self.rating
      elif self.CurrentData == "stars":
        print "Stars:", self.stars
      elif self.CurrentData == "description":
        print "Description:", self.description
      self.CurrentData = ""

# 内容事件处理
  def characters(self, content):
      if self.CurrentData == "type":
        self.type = content
      elif self.CurrentData == "format":
        self.format = content
      elif self.CurrentData == "year":
        self.year = content
      elif self.CurrentData == "rating":
        self.rating = content
      elif self.CurrentData == "stars":
        self.stars = content
      elif self.CurrentData == "description":
        self.description = content
 
if ( __name__ == "__main__"):
 
  # 创建一个 XMLReader
  parser = xml.sax.make_parser()
  # turn off namepsaces
  parser.setFeature(xml.sax.handler.feature_namespaces, 0)

# 重写 ContextHandler
  Handler = MovieHandler()
  parser.setContentHandler( Handler )
 
  parser.parse("movies.xml")

执行结果:
