Python 简单的scrapy XML spider语法错误

我只是想用scrapy制作一个简单的爬行器，从XML文件中获取数据。这就是我想到的：

from scrapy.contrib.spiders import XMLFeedSpider

class MySpider(XMLFeedSpider):
     name = 'testproject'
     allowed_domains = ['www.w3schools.com']
     start_urls = ['http://www.w3schools.com/xml/note.xml']
     itertag = 'note'

    def parse_node(self, response, node):
         to = node.select('to/text()').extract()
         from = node.select('from/text()').extract()
         heading  = node.select('heading/text()').extract()
         body  = node.select('body/text()').extract()

    def parse_node(self, response, node):
         log.msg('Hi, this is a <%s> node!: %s' % (self.itertag, ''.join(node.extract())))

        item = Item()
         item['to'] = node.select('to').extract()
         item['from'] = node.select('from').extract()
         item['heading'] = node.select('heading').extract()
         item['body'] = node.select('body').extract()
         return item

这是数据集：

当我尝试运行它时，不幸的是它不起作用。我认为这与我如何映射标签有关。这就是错误：

任何帮助都将不胜感激。

将word从更改为其他内容，在python中它是一个关键字

from是一个内置关键字，如from。。。进口将名称更改为其他名称将work@eLRuLL如果我的代码起作用，我就不会在这里了
