Variable in a selector (solutions from forum don't work)


Hello, I have a question about inserting a variable into selecter.

Here’s the original syntax with static values:
I need to use a variable (e.g. Row) instead of the static value 5. I tried to search all relevant posts here, but none of the suggested syntaxes worked. We tried several versions including:
<sap id = 'usr / lbl [43, ’ +Row+ ‘]’ />
<sap id = ‘usr / lbl [43, ‘" +Row+ "’]’ />
and several other variations but we get a syntax error most of the times and cannot continue. Often the problem seems to be that it does not recognice the variable as a variable.

In the case when we managed to get it to recognized it as a variable the robot ended with an error:

Cannot find the UI element corresponding to this selector: <wnd app='saplogon.exe' cls='SAP_FRONTEND_SESSION' title='Sledování vzájemných zápočtů (verze 2.11 build 18.10.2007)' /><sap id='usr/lbl[43,&quot;+ Row+&quot;]' />

What are we doing wrong? How should the syntax look like?

Thank you!!


Put it exactly as below directly in Selector property:
"<wnd app='saplogon.exe' cls='SAP_FRONTEND_SESSION' title='Sledování vzájemných zápočtů (verze 2.11 build 18.10.2007)' /><sap id='usr/lbl[43," + Row.ToString + "]' />"

Make sure you’re not using Selector editor, as it will encode the quotes for XML (hence the &quot; there).
Once you have the selector string as the expression, pressing the ... button will open the Expression editor which will work normally and not encode anything.


pressing the … button opens up the selector editor. I have the same problem- " changes to &quot. How to fix it?


I’m not sure if this is the best solution but what we did was create a variable to which we assigned a value equal to the selector that we wanted and than just put the variable as the only thing into the selector. It seems to work fine so far.

i tried so many ways to insert a variable in selector but it is not working, let see i’m upload error images. any one know another method or solution please let me know1method2method3method


Below is another way to add variable in selector:

  1. Assign the selector in a variable with a place holder {0}
    varSource = “”

  2. USe string.Format to assign the dynamic value
    varSelector = String.Format(varSource,“DynamicValue”)

  3. Assign the variable in selector property

Please let me know if this works.


lets try, dynamic value is Variable yes
