Get the Dynamic table data from gui in selenium webDriver -


i working on web based application testing selenium. on 1 page content dynamically loaded in table. want table data, geting "org.openqa.selenium.nullpointerelementexception" in line.

webelement table = log.driver.findelement(by.xpath(tablexpath));

i tried following complete code.

public int selectfromtable(string tablexpath, string comparevalue, int columnnumber) throws exception {     webelement table = log.driver.findelement(by.xpath(tablexpath));     list<webelement> rows = table.findelements(by.tagname("tr"));     int flag = 0;     (webelement row : rows) {         list<webelement> cells = row.findelements(by.tagname("td"));         if (!cells.isempty() && cells.get(columnnumber).gettext().equals(comparevalue)) {             flag = 1;             thread.sleep(1000);             break;         } else {             thread.sleep(2000);             flag = 0;         }     }     return flag; }

i calling above method like

string tablexpath = ".//*[@id='event_list']/form/div[1]/table/tbody/tr/td/div/table"; selectfromtable(tablexpath, eventtype, 3);

my html page like

<table width="100%">     <tbody style="overflow: auto; background-color: #ffffff">         <tr class="trodd">             <td width="2%" align="center">             <td width="20%" align="center"> account </td>             <td width="20%" align="center"> enter collection </td>             <td width="20%" align="center">             <td width="20%" align="center"> 10 </td>             <td width="20%" align="center"> 1 </td>         </tr>     </tbody>     <tbody style="overflow: auto; background-color: #ffffff">         <tr class="treven">             <td width="2%" align="center">             <td width="20%" align="center"> account </td>             <td width="20%" align="center"> resolved collection </td>             <td width="20%" align="center">             <td width="20%" align="center"> 10 </td>             <td width="20%" align="center"> 1 </td>         </tr>     </tbody> </table>

my solution similar case - wanted row number table, given column contains specific text.

// method searches in given column of table , return number of row // first value spotted (title row counts 0 row , // skipped). if no value found 0 returned. given column number // starts 1.  public integer gettablerownumberwithvalue(string tableid, string value,         integer columnnumber) {      webelement table = getdriver().findelement(by.id(tableid));     list<webelement> rows = table.findelements(by.tagname("tr"));      int j = 0;     int = 0;     (webelement row : rows) {         // skip title row counts 0 row.         if (i > 0) {             if (row.findelements(by.tagname("td")).get(columnnumber - 1)                     .gettext().equals(value)) {                 j = i;                 break;             }         }         i++;     }     return j; }

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
