extracting link with scrapy and selenium

Python

I am using selenium and scrapy to navigate to a table of data and I would like to extract the links/href to a csv file. so far everything i have tried doesn't seem to work and I'm unsure what to try or how to go about getting the links.

here's the important part of the table I am trying to extract the links/href from:

<tr class="even">

<td class="paddingColumnValue"> </td>

<td class="nameColumnValue"><a href="/m/app?service=external/sdata_details&sp=12812" class="sdata" title="Click here for additional details.">click</a></td>

<td class="amountColumnValue">$600,000.00</td>

<td class="myListColumnValue"><a href="" onclick="doMyListButton(this.firstChild.getAttribute('src'),this.name);myListHandler(this.name);return false;"  önmouseover="return true" name="12812"><img src="/m/images/add.gif" border="0" title="Click to add this to your list" name="A12812"></a></td>


</tr>

the closest I've gotten to actually getting data is with this code...(note table id = search_results)

import time
from scrapy.item import Item, Field
from selenium import webdriver
from scrapy.spider import BaseSpider
from scrapy.contrib.linkextractors.sgml import SgmlLinkExtractor
from scrapy.selector import HtmlXPathSelector

class ElyseAvenueItem(Item):
    link = Field()

class ElyseAvenueSpider(BaseSpider):
    name = "elyse"
    allowed_domains = ["domain.com"]
    start_urls = [
    'http://www.domain.com']
    
    def __init__(self):
        self.driver = webdriver.Firefox()

    def parse(self, response):
        self.driver.get(response.url)
        el1 = self.driver.find_element_by_xpath("//*[@id='headerRelatedLinks']/ul/li[5]/a")
        el1.click()
        time.sleep(2)
        el2 = self.driver.find_element_by_xpath("/html/body/form/table/tbody/tr[2]/td[2]/table/tbody/tr/td[3]/p[3]/a[1]")
        if el2:
            el2.click()
            time.sleep(2)
        el3 = self.driver.find_element_by_xpath("/html/body/form/table/tbody/tr[2]/td[2]/table[1]/tbody/tr/td[3]/a")
        if el3:
            el3.click()
            time.sleep(20)
            
        
            titles = self.driver.find_elements_by_class_name("sdata")
            items = []
            for titles in titles:
                item = ElyseAvenueItem()
                item ["link"] = titles.find_element_by_xpath("//*[@id='search_results']/tbody/tr[2]/td[2]/a")
                items.append(item)
                return item

output to csv:
selenium.webdriver.remote.webelement.webelement object="" at="" 0x03f16e90=""

thank you for the help. i can post more of my attempts and their output if that will help. Like I said, what i need is the href
