c# - Selenium.NoSuchElementException with dynamic tables -

-

please me problem!

at moment, scraping website using selenium firefox driver in c#. data on website dynamically filled tables cover data concerning future dates.

while structure of table same both future , past dates, tables being updated during selenium call throw "nosuchelementexception" concerning iwebelements there.

these relevant copied xpaths tables. 1 past date, on works fine, , 1 on future date, on exception thrown. can see, identical.

xpath 18052015

/html/body/div[1]/div/div[2]/div[5]/div[1]/div/div[1]/div[2]/div[1]/div[7]/div[1]/table/tbody/tr[1]/td[1]/div/a[2]

xpath 05022016

/html/body/div[1]/div/div[2]/div[5]/div[1]/div/div[1]/div[2]/div[1]/div[7]/div[1]/table/tbody/tr[1]/td[1]/div/a[2]

using findelements(by.xpath(...)) function, use 2 foreach loops go through highlighted tr's , td's in xpath text in a[2] header. in both cases, dom in firefox firebug seems identical in both cases. difference have observed between 2 tables fact every few seconds, 1 concerning future date updates values (also resetting table when looked @ via firebug). here have relevant piece of code, important comment.

            foreach (var tr in table.findelements(by.xpath("div/table/tbody/tr")))             {                 foreach (var td in tr.findelements(by.xpath("td")))                 {                     if(td.getattribute("innerhtml").contains("some stuff"))                     {                         // part reached, condition satisfied. > x relevant value, assigned proper value when error thrown, still throws exception.                         x = td.findelement(by.xpath("div/a[2]")).getattribute("href").split('/')[4];                         bmid = getbookmakerid(bmname);                     }                     if(td.getattribute("class").contains("some other stuff"))                     {                      }                 }

has of had similar problems before , able solve them?

could add wait every steps call findelement? see example below:

iwait<iwebelement> wait = new defaultwait<iwebelement>(table); wait.timeout = timespan.fromseconds(5); wait.pollinginterval = timespan.frommilliseconds(300); locator = by.xpath("div/table/tbody/tr"); readonlycollection<iwebelement> rows;  wait.until(e => e.findelements(locator).count > 0); rows = table.findelements(locator);   foreach (var tr in rows) {      wait = new defaultwait<iwebelement>(tr);     wait.timeout = timespan.fromseconds(5);     wait.pollinginterval = timespan.frommilliseconds(300);     locator = by.xpath("td");     readonlycollection<iwebelement> cells;      wait.until(e => e.findelements(locator).count > 0);     cells = tr.findelements(locator);      foreach (var td in cells)     {         if (td.getattribute("innerhtml").contains("some stuff"))         {             // part reached, condition satisfied. > x relevant value, assigned proper value when error thrown, still throws exception.             wait = new defaultwait<iwebelement>(td);             wait.timeout = timespan.fromseconds(5);             wait.pollinginterval = timespan.frommilliseconds(300);             locator = by.xpath("div/a[2]");             iwebelement link2;              wait.until(e => e.findelements(locator).count > 0);             try             {                 link2 = td.findelement(locator);             }             catch (nosuchelementexception ex)             {                 throw new nosuchelementexception("unable find element, locator: \"" + locator.tostring() + "\".");             }             x = link2.getattribute("href").split('/')[4];             bmid = getbookmakerid(bmname);         }         if (td.getattribute("class").contains("some other stuff"))         {          }     } }

if still error, can debug test in visual studio easily.

stringtemplate - StringTemplate4 if conditional with length -

i need generate following kinds of code stringtemplate4: methodfoo0(connection conn); methodfoo1(connection conn, int arg1); methodfoo2(connection conn, int arg1, int arg2); etc. the "connection conn" part present passing method name , rest of arguments st template. template looks follows: <methodname>(connection conn, <args; separator=", ">); this works produces comma when there no arguments @ (except conn): methodfoo0(connection conn,); to eliminate comma tried using if conditional , length st4 function couldn't work although tried various combos following: <methodname>(connection conn <if (length(fieldsinfind) \> 0)>,<else><endif><fieldsinfind; separator=", ">) ... , others failed parsing-related error ( mismatched input ). in end, gave , resorted passing comma parameter template either "," or empty string "" based on pre-rendering logic. you check p
