I have already submitted a Stackoverflow question
(https://stackoverflow.com/questions/27115336/issues-looping-over-a-table-in-scrapy)
but I thought I'd ask here as well. I have a confusing situation with how
to loop a selector. The gist of my code is this.
rows = hxs.xpath('//table[@class="t1"]//tr')for row in rows:
cells = row.xpath('td').extract()
I grab a list of table rows, loop over that and get a list of row cells. The
preceding code does not work, I get a blank list. However, if instead of
looping over the selector I pick a selector from the SelectorList using an
index, it works no problem.
rows = hxs.xpath('//table[@class="t1"]//tr')
cells = rows[1].xpath('td').extract() #this works
So what am I doing wrong? I followed the docs section on Nested selectors and
that didn't help. There should be no difference between looping a selector and
indexing it.
