passing selenium response url to scrapy

I am learning Python and am trying to scrape this page (http://ift.tt/1H1uQNP) for a specific value on the dropdown menu. After that I need to click each item on the resulted table to retrieve the specific information. I am able to select the item and retrieve the information on the webdriver. But I do not know how to pass the response url to the crawlspider.

driver = webdriver.Firefox()
driver.get('http://ift.tt/1H1uQNP')
more_btn = WebDriverWait(driver, 20).until(
     EC.visibility_of_element_located((By.ID, '_button_select'))
            )  
more_btn.click()

## select specific value from the dropdown
driver.find_element_by_css_selector("select#tabJcwyxt_jiebie >     option[value='teyaoxgrs']").click()
driver.find_element_by_css_selector("select#tabJcwyxt_jieci > option[value='d11jie']").click()
search2 = driver.find_element_by_class_name('input_a2')
search2.click()
time.sleep(5)

## convert html to "nice format"
text_html=driver.page_source.encode('utf-8')
html_str=str(text_html)

## this is a hack that initiates a "TextResponse" object (taken from the Scrapy module)
resp_for_scrapy=TextResponse('none',200,{},html_str,[],None)

## convert html to "nice format"
text_html=driver.page_source.encode('utf-8')
html_str=str(text_html)

resp_for_scrapy=TextResponse('none',200,{},html_str,[],None)

So this is where I am stuck. I was able to query using the above code. But How can I pass resp_for_scrapy to the crawlspider? I put resp_for_scrapy in place of item but that didn't work.

## spider 
class ProfileSpider(CrawlSpider):
name = 'pccprofile2'
allowed_domains = ['cppcc.gov.cn']
start_urls = ['http://ift.tt/1H1uQNP']    

def parse(self, resp_for_scrapy):

    hxs = HtmlXPathSelector(resp_for_scrapy)
    for post in resp_for_scrapy.xpath('//div[@class="table"]//ul//li'):
        items = []
        item = Ppcprofile2Item()
        item ["name"] = hxs.select("//h1/text()").extract()
        item ["title"] = hxs.select("//div[@id='contentbody']//tr//td//text()").extract()
        items.append(item)

    ##click next page      
    while True:
        next = self.driver.findElement(By.linkText("下一页"))
        try:
            next.click()
        except:
            break

    return(items)

Any suggestions would be greatly appreciated!!!!
