Not able to reference value of variable in Robot Framework

Question

In Robot Framework, I want to reference the value of a variable, I had set earlier. But when I reference the value by:

xpath= //*[text()=\${uid}]

I do not get the value of the variable uid but instead, I get an error

InvalidSelectorException: Message: invalid selector: 
Unable to locate an element with the xpath expression //*[text()=${uid}] because of the following error:
SyntaxError: Failed to execute 'evaluate' on 'Document': 
The string '//*[text()=${uid}]' is not a valid XPath expression.

It just takes the uid as the part of the XPath instead of referencing it. As you can see, I tried to escape the $ sign by adding a backslash (\), but it doesn't do anything. It is not even shown in the expression shown in the error.

If anyone has any solution, kindly share them.

Answer 1

Have you tried putting the variable in double quotes?

//*[text()="${uid}"]

Answer 2

Here is one approach to call the XPath with dynamic value.

1.Create one python file name ConfigVariables.py

uid="test" 
my_Xapth='xpath=//*[text()=\''+uid+'\']'

Save this file.

2.Import this file in .robot file under the setting keyword.

 *** Settings ***
 Variables ../Variables/ConfigVariables.py

Now try to call my_Xapth variable in the test case, I hope this should work.
