r - Web scrape with rvest from a table that is not defined -


i trying table website : http://www.oddsportal.com/american-football/usa/nfl-2012-2013/results/

i want table in middle of page.

i tried different ways in vain.

library("rvest") library(dplyr)  url1 <- "http://www.oddsportal.com/american-football/usa/nfl-2012-2013/results/" table <- url1 %>%   read_html() %>%   html_nodes(xpath='//*[@id="tournamenttable"]') %>%    html_table(fill = t)

this not work because believe table not defined table.

i tried grab rows separately using:

 df <- mps1 %>%       html_nodes(css = "tr.odd.deactivate,tr.center.nob-border")

but obtains nothing.

any idea how can it?

thanks

based on previous questions people trying scrape site, table dynamically generated. far know, way deal pages use rselenium - automates browser.

after lot of trial , error, following code seems work (using chrome on windows 10)...

library(rselenium) library(rvest) library(dplyr)  url <- "http://www.oddsportal.com/american-football/usa/nfl-2012-2013/results/" rd <- rsdriver(port=4444l,browser="chrome") remdr <- rd$client  remdr$navigate(url)  page <- remdr$getpagesource() remdr$close() #you can leave open if doing several of these: close @ end  table <- page[[1]] %>%   read_html() %>%   html_nodes(xpath='//table[@id="tournamenttable"]') %>% #specify table there div same id   html_table(fill = t)  table <- table[[1]]  head(table)    american football» usa»nfl 2012/2013   american football» usa»nfl 2012/2013   american football» usa»nfl 2012/2013 american football» usa»nfl 2012/2013 american football» usa»nfl 2012/2013 american football» usa»nfl 2012/2013 1              03 feb 2013 - play offs                03 feb 2013 - play offs                03 feb 2013 - play offs              03 feb 2013 - play offs                                 1.00                                 2.00 2                                                                                                                                                                                           na                                   na 3                                23:30 san francisco 49ers - baltimore ravens san francisco 49ers - baltimore ravens                                31:34                                 1.49                                 2.71 4              28 jan 2013 - stars                28 jan 2013 - stars                28 jan 2013 - stars              28 jan 2013 - stars                                 1.00                                 2.00 5                                                                                                                                                                                           na                                   na 6                                00:00                              nfc - afc                              nfc - afc                                62:35                                 2.03                                 1.83   american football» usa»nfl 2012/2013 1                                  b's 2                                      3                                    9 4                                  b's 5                                      6                                    9

the odds coming out decimal numbers, unfortunately, can work that.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
