Can the use of Beautiful Soup with Scrapy increase the performance
well the answer is you should try to parse couple of pages with HtmlSelector then Using beautiful Soup. and find some stats.
2ndly most of people use beautiful Soup even lxml for parsing because they already used to for using this.
Scrapy basic motive is Crawling if you are not comfortable with Xpath you can go with beautiful Soup , lxml (although lxml package also support xpath) even Only Regex for Parsing.
I am doing crawling everything in scrapy.
I have seen that many people are using beautiful Soup for parsing.
I just wanted to know that is there any advantage in terms of speed , efficiency or more slectrors etc which help me in creating spiders and crawlers or scrapy alone should be enough for me
