It seems to me that this is the actual issue: 

SyntaxError: Failed to execute 'evaluate' on 'Document': The string '//tbody[@id='ContentPlaceHolder1_ContentPlaceHolder1_calExtStartDate_daysBody']/tr[2]/[td][1]' is not a valid XPath expression.

Have you validated your xpath expression? 

Kind regards,

Anne

Hi Anne yes I have evaluate my expression. it works when i check in the google built in developers tool. it was actually able to locate because it has id tags. but i was able to correct this issue. i need to go higher to its parent:

<parent element>

  -<table>

       <table>   <---- i was here, it corrected it when i pointed at the parent element. usually it words for me by just the id. for some reason it didnt.

          <element>

               

Thank you very much. I appreciate the help

I don't think `[td][1]` you had in the xpath is valid.

how do you iterate through the elements in the table. when i check my xpath in google chrome it was able to locate the element.

example: 

//div[@class='mainContainer']/table/tbody/tr/td[2]/div/div/div/div[@id='ContentPlaceHolder1_ContentPlaceHolder1_pnlPopup']/div[@class='popUpContent']/table/tbody/tr[5]/td[3]/div[@id='ContentPlaceHolder1_ContentPlaceHolder1_calExtStartDate_container']/div[@id='ContentPlaceHolder1_ContentPlaceHolder1_calExtStartDate_popupDiv']/div[@id='ContentPlaceHolder1_ContentPlaceHolder1_calExtStartDate_body']/div[@id='ContentPlaceHolder1_ContentPlaceHolder1_calExtStartDate_days']/table[@id='ContentPlaceHolder1_ContentPlaceHolder1_calExtStartDate_daysTable']/tbody[@id='ContentPlaceHolder1_ContentPlaceHolder1_calExtStartDate_daysBody']/tr/td

Datepicker search valid date
   ${countr} =  get element count  ${calendardatetable}/tr
   log  ${countr}
   ${countr}=  evaluate  ${countr}+ 1
   :FOR   ${i}   IN RANGE  1   ${countr}
   \  ${counttd}=  get element count   ${calendardatetable}/tr[${i}]/td
   \  Datepicker search td date   ${i}  ${counttd}

Datepicker search td date
    [Arguments]  ${ctri}  ${ctrx}
    log  ${ctri}
    log  ${ctrx}
    ${countx} =  get element count  ${calendardatetable}/tr[${ctri}]/td
    ${countx} =  evaluate  ${countx} + 1
    log  ${countx}
    :FOR   ${x}   IN RANGE  1  ${countx}
         \  ${classsttrib} =  get element attribute   ${calendardatetable}/tr[${ctri}]/td[${ctrx}]   class
         \  log   ${classsttrib}

I am trying to get the value of the class using get attribute. my test passed but was not able to get the attribute and it returns empty. pls see logs

thanks Pekka.

chris

Ugh

The error you receive is coming from Chrome, I would assume that if you change singe quote to double quote: 

//tbody[@id='ContentPlaceHolder1_ContentPlaceHolder1_calExtStartDate_daysBody']/tr[2]/[td][1]

to: 

//tbody[@id="ContentPlaceHolder1_ContentPlaceHolder1_calExtStartDate_daysBody"]/tr[2]/[td][1]

it might work better.

I've corrected my script. it passed but it was not able to get the attribute class.

Datepicker search td date
    [Arguments]  ${ctri}  ${ctrx}
    log  ${ctri}
    log  ${ctrx}
    ${countx} =  get element count  ${calendardatetable}/tr[${ctri}]/td
    ${countx} =  evaluate  ${countx} + 1
    log  ${countx}
    :FOR   ${x}   IN RANGE  1  ${countx}

         \  check that element exist  ${calendardatetable}/tr[${ctri}]/td[${ctrx}]
         \  ${classsttrib}=  SeleniumLibrary.Get Element Attribute   ${calendardatetable}/tr[${ctri}]/td[${ctrx}]  class
         \  log   ${classsttrib}


Select Datepicker Date
    [Documentation]     Select given day from datepicker
    [Arguments]     ${dateElem}     ${expectedMonthYear}    ${clickElement}
    Input Text  ${dateElem}    ${Empty}    # open the datepicker
    ${monthyear}=   Get Datepicker MonthYear
    :FOR    ${Index}    IN RANGE    1   31
    \   Run Keyword If  '${monthyear}' == '${expectedMonthYear}'   Exit For Loop
    \   Click Link    //*/div[@id='ui-datepicker-div']//*/a[contains(@class, 'ui-datepicker-prev')]
    \   ${monthyear}=   Get Datepicker MonthYear
    Click Link    ${clickElement}

i am trying to get know if the attribute of the element which is td that has a class='ajax__calendar invalid'] so that i will skip this and can select a valid date in the date picket.

my code now passed but returns empty

thanks for the help.
