python - multiple download folders using Selenium Webdriver? -

-

i'm using selenium webdriver (in python) automate donwloading of thousands of files. want files saved in different folders. following code works, requires quitting , re-starting webdriver multiple times, slows down process:

some_list = ["item1", "item2", "item3"] # on 300 items on actual code item in some_list:     download_folder = "/users/myusername/desktop/" + item     os.makedirs(download_folder)     fp = webdriver.firefoxprofile()     fp.set_preference("browser.download.folderlist", 2)     fp.set_preference("browser.download.manager.showwhenstarting", false)     fp.set_preference("browser.download.dir", download_folder)     fp.set_preference("browser.helperapps.neverask.savetodisk", "text/plain")     browser = webdriver.firefox(firefox_profile = fp)      # bunch of code accesses site , downloads files      browser.close()     browser.quit()

so, @ every iteration have quit webdriver , re-start it, pretty innefficient. there better way this? apparently can't change firefox profile after webdriver instantiated (see this , this previous questions), perhaps there alternative i'm missing?

(mac os x 10.6.8, python 2.7.5, selenium 2.2.0)

no, don't think can it.

option one: specify different default directories 1 firefoxprofile

you can't. in opinion, issue firefox, not selenium. however, firefox limitation looks correct design me. browser.download.dir default download destination, if allows multiple directories, that's not "default" anymore.

option two: switch multiple firefoxprofile 1 driver instance

if not doing in firefox, can firefoxprofile switched same driver instance? far know, answer no. (you have done research on this)

option three: use normal non-selenium way downloading

if want avoid using auto-downloading approach , normal way (like auto-it etc.), falls in category of "how download files selenium , why shouldn’t". in case, code can simplified.

some_list = ["item1", "item2", "item3"] # on 300 items on actual code item in some_list:     download_folder = "/users/myusername/desktop/" + item     some_way_magically_do_the_downloading(download_folder)

i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution:

java - Why does my date parsing return a weird date? -

here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
