还是用xml的模板爬xml 来的直接。

TestItem in items.py:

class TestItem(scrapy.Item): id = scrapy.Field() name = scrapy.Field() description = scrapy.Field()

main:

from scrapy import log
from scrapy.contrib.spiders import XMLFeedSpider
from myproject.items import TestItem

class MySpider(XMLFeedSpider):
    name = 'example'
    start_urls = ['portfolio xii xml']
    iterator = 'xml' # This is actually unnecessary,since it's the default value
    itertag = 'PortfolioStatistics'  #Name of Parent Node

    def parse_node(self,response,node):
        item = TestItem()
        item['id'] = node.xpath('@_SalePosition').extract()  #Get Parent Node Attribute
        item['name'] = node.xpath('EquityStyle/EquityStyleCoreValue/StyleBox/text()').extract()  #Get son of grandson
        item['description'] = node.xpath('BondStatistics/EffectiveDuration/text()').extract() #Get Grandson
        return item

Output: [ {“description”: [“0.53”],“name”: [“6”],“id”: [“L”]} ]
