html - xpath finds element in developers console but not in scrapy.response -

-

i'm trying scrape price first ticket here page using xpath:

'.//*[@class="price"]/text()'

this works in developer's console, not when run in scrapy shell using response.xpath. have tried following in shell:

'.//*[@class="initial"]/div[@class="price"]/text()'

and

'//*[@id="tvb901769989"]/div[1]/div[4]' (although don't think id property can used in shell this).

is there wrong xpaths i've used, or there thing different way page works? appreciated. thanks!

this happens because checking @ different requests, page see doesn't have information need inside file, gets dynamically, in case from: www.vividseats.com/javascript/tickets.shtml?productionid=1771684

there can check prices on json format, think 1 item:

{    "s":"section 111",    "r":"8-22",    "q":"4",    "p":"692.00",    "i":"vb782041491",    "d":"111",    "n":"zone seating. seller committing procure these tickets upon receipt of order. after place order , order confirmed, guarantee tickets within listed zone  or section listed or 1 comparable , receive these tickets in time event or  money back. orders exceeding 4 tickets may split different rows within requested  zone or section.",    "f":"0",    "l":"section 111",    "g":"0",    "e":"0",    "h":"07/21/15",    "t":"0",    "v":"",    "c":"84352",    "z":"1",    "rhdn":"0",    "ind":"0",    "sd":"0" }

where p contains price.
