scrapy xpath 正则如何使用？

Question

xpath的值是.//*[@id='site-list-content']/div[6]/div[3]/a/div
这种形式
其中div[6]是第六个值，想要在循环中获取没个div下的信息，正则要怎么写？
sites = sel.xpath('//*[@id="site-list-content"]')
items = []
i = 1
for site in sites:
item = DmozItem()
item['title'] = site.xpath('div|[6]div|3|/a/div/text()').extract()
