variable interpolation/parsing issue
times loop variable interpolation truncates XPath expressions containing ${!times}`

When using ${!times} inside an XPath locator, the generated XPath is sometimes truncated during execution.
Example intended XPath:
xpath
//*[@id=x‘birthday’]/div/div/span[${!times}]/a/span/b
Expected after substitution
//*[@id=‘birthday’]/div/div/span[3]/a/span/bActual behavior observed: after 2nd iteration (iteration 1 works as expected, iteration 2 onward is truncated)
//*[@id=‘birthday’]/div/div/span[3]/a/span (the /b is truncated)
or Command storeAttribute
//*[@id=‘birthday’]/div/div/span[4]/a/span@class
works on 1st iteration becomes truncated on 2nd iteration onward//*[@id=‘birthday’]/div/div/span[4]/a/span
I switched to the internal loop ${!loop} and the issue went away. The xpaths are not truncated.
When testing I added the xpaths to a variable and then expanded the variables during runtime, however the xpaths were still truncated on the 2nd iterations onward.

There are a few other instances where I use “times“ to iterate through xpaths where I get many #LNF returned but I haven’t analyzed those as the results were not critical and the erros were ignored. When I get a chance I’ll check to see if the same behavior is seen.
Summary
in this use case the xpath are getting truncated on the 2nd iterations whether using the raw xpath or by extrapilating the xpaths from a variable. Just curious if this is a bug.
BTW, I still have the nonworking code if you’d like to see that as well.
Thank you.
