how to parse a string to spider from another script
You can override the start_requests() method in your spider to get the starting requests (which, by default, are generated using the urls in the start_urls attribute).
I am new to python and scrapy . 
I am running the scrapy-ctl.py from another python script using 
subprocess module.But I want to parse the 'start url' to the spider from 
this script itself.Is it possible to parse start_urls(which are 
determined in the script from which scrapy-ctl is run) to the spider? 
I will be greatful for any suggestions or ideas regarding this....:) 
Thanking in advance....
