title: How to select tables in scrapy using selectors whose class id have spaces in it?
body: <p>I'm trying to select all the tables inside a division which has xpath similar to <code>//*[@id="mw-content-text"]/table[@class="wikitable sortable jquery-tablesorter"]</code>. But the selector doesn't returns any value. How can I get through those tags which have spaces in their id/class ?</p>
